Focus and scope

Experimental, theoretical, and applied articles on all aspects of plant, algae, and fungi biology and evolution are welcome. The submitted manuscript or its essential content must not have been previously published or be under consideration for publication elsewhere. Contributions should be substantial, written in high-quality English, and demonstrate general interest. Manuscripts reporting on locally specific aspects are discouraged unless the implications of the results are broad. Manuscripts with agronomic subjects are expected to contain a substantial amount of basic plant biology.

Editorial Policy

Open Science Compliance

Open Science Compliance Form: https://wp.scielo.org/wp-content/uploads/Open-Science-Compliance-Form_en.docx

The Open Science movement proposes guidelines for collaborative, shared, and public scientific practice. ABB adopts a series of practices, such as the policy of open access, the code of good practices for editors, and the use of social networks for the dissemination of published works. Additionally, it requires precise indication of the role of each author in articles with multiple authors and encourages the sharing of data sets for analysis, instruments, statistical analysis scripts, pipelines, and additional materials, made available in open online repositories. ABB also encourages the publication of preprint articles on public platforms, such as SciELO Preprints, bioRxiv, and Preprints, so that, if necessary, they can be openly discussed before being published. As a consequence, articles communicating research should indicate and reference the availability of the underlying content used in the research and the obtained results.

ABB offers authors and reviewers options for opening the peer review process, with or without the identification of their names. Authorization for the disclosure of names can be provided by authors at the time of article submission and by reviewers when filling out the Open Science Compliance Form: https://wp.scielo.org/wp-content/uploads/Open-Science-Compliance-Form_en.docx.

Ethics in Publication

The submission of an article implies that the work described has not been previously published (except in the form of an abstract, published lecture, or academic thesis). The article will first be evaluated for compliance with the journal’s guidelines and then analyzed by similarity verification software by the technical staff.

Digital Preservation

This journal follows the standards defined in the Digital Preservation Policy Program of the SciELO Program.

Editorial Policy

Preprints

Acta Botanica Brasilica encourages the publication of preprint articles on public platforms such as SciELO Preprints, bioRxiv, and Preprints so that, when appropriate, they can be openly discussed before formal publication. A preprint is defined as a manuscript ready for submission to a journal and deposited on reliable preprint servers before or concurrently with journal submission. This practice, along with continuous publication, serves as mechanisms to expedite research communication. The use of preprints is optional and at the discretion of the authors. If a preprint is published, its DOI should be identified in the submission process.

Peer Review Process

All authors will receive an email confirming the submission of the manuscript, along with the corresponding reference number. The editorial board will assess adherence to general instructions, such as format and linguistic appropriateness, and perform a similarity check. The Editor-in-Chief, in association with the editorial board, will evaluate the manuscript’s alignment with the journal’s scope and audience, as well as its quality, relevance, and contribution, and decide on its suitability for peer review. Manuscripts that do not adhere to the format will be returned to the authors. Manuscripts passing the initial editorial evaluation are sent to at least two anonymous reviewers who have 30 days to provide their reviews. The name of the editor or editors responsible will be published in the final version of the manuscript.

ABB is committed to editorial transparency and adheres to quality standards. For peer-review information disclosure, we follow the guidelines suggested by SciELO, which offer three options for advancing openness. The first option is to publish the name or names of the editors responsible for the evaluation in the final article. The second option is to give reviewers the choice to directly communicate with the corresponding author with or without revealing their identities. The third option is to offer the choice to publish approval reviews of articles with or without identifying the reviewers. Reviews constitute a new type of literature in the SciELO methodology and receive similar treatment to research articles. The ABB journal adopts Single-Blind peer review.

Open Data

Valuing the scientific principles of openness, transparency, and reproducibility, Acta Botanica Brasilica encourages the sharing of all datasets used in the analyses, including statistical analysis codes (scripts and pipelines), other codes, methods, and additional materials in open online repositories such as SciELO data, Figshare, and OSF, if they cannot be published in the article itself. This information should be indicated in the manuscript.

The deposition of nucleotide sequences, including raw reads from high-throughput sequencing, is mandatory in repositories such as GenBank (http://www.ncbi.nlm.nih.gov/genbank), NCBI SRA – Sequence Read Archive (https://www.ncbi.nlm.nih.gov/sra), and/or others like Genome Sequence Archive (GSA – http://bigd.big.ac.cn/gsa).

Specimen vouchers of any organisms should preferably be deposited in collections that share their data through the Global Biodiversity Information Facility (GBIF).

Fees

The journal charges a fee of R$ 800 (eight hundred Brazilian reais) per article accepted for publication. There is no submission or evaluation fee.  Authors will be required to pay the fee upon receipt of the acceptance letter for publication. Members of the Brazilian Botanical Society (Sociedade Botânica do Brasil – SBB), are exempt from fees for one article per year, provided it does not exceed 12 in the final PDF. For SBB members, if the manuscript exceeds the 12-page limit, an additional fee of R$ 15 per extra page in the final PDF will be applied. To become a member of the SBB, please visit https://www.botanica.org.br/. We emphasize that, as a journal maintained by a scientific society supported mainly by memberships, we are unable to waive the article fee, even for corresponding authors residing in low- and middle-income countries and territories.

Ethics and Misconduct, Correction and Retraction Policy

With the purpose of ensuring integrity and ethical editorial conduct, promoting the identification of practices such as plagiarism, academic dishonesty, duplicate publication, any other fraudulent methods, and potential ethical violations, we strongly recommend that authors consult the COPE website, where guidelines on research ethics for authors and editors are available.

Authors must ensure that data obtained, analyzed, or interpreted from other publications are clearly referenced and that the intellectual work of other authors is acknowledged and properly cited.

Regarding authorship, only those who have actively and substantially contributed to all stages of the research and article preparation should be identified as authors. No researcher who has fully participated in the research and writing of the article should be omitted. It is essential that authors carefully review the list and order of authors before submitting their manuscripts and provide the final list of authors at the time of submission. Authors should provide in the manuscript body a description of each author’s contribution following the criteria of the Contributor Roles Taxonomy – CrediT (see author instructions). Changes to authorship during the evaluation or after acceptance of the text will not be permitted. After submission, the Editor-in-Chief and/or the editorial board may request formal clarifications regarding the participation of the listed authors. Upon receipt of these clarifications, the Editor-in-Chief, together with the editorial board, will make decisions regarding the appropriate procedures concerning the manuscript.

Any article already published and identified as having misconduct will remain indexed in the journal’s database as retracted. Retraction of an article consists of documenting the reason for retraction, properly referenced and communicated by the author, editor, or other authorized agent, and published in the journal. Partial retraction may occur when misconduct applies only to a specific part of the article without compromising the entire published research. The retraction registration process is initiated upon receipt of a formal communication to the Editor-in-Chief, who will notify SciELO. This communication must include the retraction text, explaining the reasons for retracting the article.

Errors not involving misconduct will be corrected through errata. The journal will publish corrections or retractions as soon as possible. Any additions or modifications to the submitted text can only be made before manuscript acceptance and must be approved by the Editor-in-Chief.

The Editor-in-Chief will only consider changes to the text under exceptional circumstances after manuscript acceptance. During the evaluation of the change request, the publication of the manuscript will be suspended.

Policy on Conflict of Interest

Conflict of interest can be of a personal, commercial, political, academic, or financial nature. Conflicts of interest may arise when authors, reviewers, or editors have interests that could influence the drafting or evaluation of manuscripts. When submitting the manuscript, authors are responsible for acknowledging and disclosing any financial or other conflicts of interest that may have influenced the work. If there is, even potentially, a conflict of interest, the author(s) must inform it in a separate document signed and attached to the submission platform. For more information see: Disclosure of Financial and Non-Financial Relationships and Activities, and Conflicts of Interest.

Reviewers should inform editors about any conflicts of interest that may influence the manuscript’s analysis and should declare themselves disqualified to review it if such conflicts occur. They should consider all types of conflicts of interest before evaluating the manuscript, including work relationships with the authors, such as participation or previous participation in joint research projects, scientific collaboration with research groups, mentoring relationships with the authors, or financial interest in the project related to the manuscript. Additionally, editors should avoid making decisions about manuscripts that may conflict with their own interests, such as those submitted by authors from their departments, research collaborators, or relatives.

Adoption of similarity software

Acta Botanica Brasilica considers plagiarism an unacceptable practice. As part of its initiatives to promote academic integrity and prevent plagiarism in its publications, it adopts the Crossref Similarity Check service provided by iThenticate for all submitted manuscripts before sending them for peer review. Similarity will be considered when the software indicates long texts, with more than 30%, suggesting plagiarism. If plagiarism is detected, authors will be notified, and formal explanations will be requested regarding any doubts, issues, and/or obscure points that may arise from the manuscript’s similarity assessment. Once the results and any clarifications are received, the Editor-in-Chief, in conjunction with the Executive Editors and, if necessary, the Editorial Board, will decide on the procedures regarding the manuscript. If duplication is confirmed, the article will be rejected.

Ethics Committee, authorizations, and permissions

Authors must attach a statement of approval from the ethics committee of the institution responsible for approving the research. Licenses, permissions, and authorizations for access to genetic heritage, access to traditional knowledge associated with genetic heritage, collection of biological material outside and inside protected areas, indigenous lands, quilombola territories, and other traditional peoples and communities’ territories, as well as registration in the National System for Management of Genetic Heritage and Associated Traditional Knowledge (SisGen), in the case of work with native species of Brazil, are the responsibility of the authors and must be explicitly cited in the published articles.

Copyright

Authors of articles published by Acta Botanica Brasilica retain the copyright of their works, licensing them under the Creative Commons Attribution CC-BY 4.0 license, which allows articles to be reused and distributed without restriction, provided that the original work is correctly cited.

Intellectual Property and Terms of Use

Responsibility of the website:

The website reserves the right to make normative, orthographic, and grammatical changes to the originals to maintain the standard language usage while respecting the authors’ style.

Author’s responsibility:

Authors retain all rights to their works, with their reprinting, deposit, or partial or total republication subject to indicating the first publication in the journal through the CC-BY license. The original source of publication must be cited. Authors are solely responsible for the data, concepts, and opinions presented in the articles, as well as the accuracy of the documents and bibliographic references.

All content of the journal and articles published by Acta Botanica Brasilica, unless specified otherwise, are licensed under the Creative Commons Attribution License: CC-BY https://br.creativecommons.org/licencas/.

Authors of articles published by Acta Botanica Brasilica retain the copyright of their works, licensing them under the Creative Commons Attribution License, which allows articles to be reused and distributed without restriction, provided that the original work is correctly cited.

Guidelines for manuscript preparation and submission

Manuscripts should be submitted electronically through the website https://mc04.manuscriptcentral.com/abb-scielo.

Submissions must be made exclusively in English. Authors are responsible for ensuring the quality of the English language in their manuscripts. The editorial board will evaluate the language adequacy upon submission, and if deemed inappropriate, the manuscript may be rejected. Starting from April 1, 2024, authors for whom English is not their first language must compulsorily provide certificates of review by a specialized scientific translator in the English language, whether native or not, at the time of manuscript acceptance. This step is mandatory to enhance the clarity of academic content, ensuring it is fully understandable to journal editors and reviewers. The certificate attesting to proficiency in the English language must be submitted within a maximum of two week after acceptance. Accepted manuscripts will only be sent for editing and subsequent publication after the submission of the English review certificate. It is important to note that language verification does not guarantee publication acceptance. Authors are responsible for covering all costs associated with such services.

Please never create a new account if you are already registered.

If you are unable to access our web-based submission system, please contact the editorial assistant ([email protected]).

Cover Letter

All manuscripts must be submitted with a cover letter, which should include an approximately 80-word summary of the scientific strengths of the article that the authors believe qualify it for consideration by Acta Botanica Brasilica. The cover letter should also include a statement that the manuscript reports unpublished work and is not under active consideration for publication elsewhere, nor has it been accepted for publication, nor has it been published in whole or in part (except in abstract form).

If the authors have opted to submit a preprint version of the manuscript, this should be presented in the cover letter, along with the DOI of the preprint.

Manuscript Preparation

All manuscripts must strictly adhere to the following guidelines:

• Use Times New Roman font, size 12.
• Double-space between lines.
• Margins should be 25 mm wide.
• Set the paper size to A4 (210 x 297 mm).
• All pages must be numbered sequentially.
• Each line of text should be numbered, starting with line 1 at the top of each page.

 

Acceptable file formats are .doc, .docx, and .rtf. Adobe® PDF (.pdf) files will not be accepted. When applicable, the manuscript file should include a list of figure captions and table headers at the end. The article file should not contain illustrations or tables, which should be submitted in separate files. All tables should be submitted in a single file. Do not include the field code.

The first page should indicate the type of article (Original Articles, Review Articles, Viewpoints, Methods, or Scientific Notes) and provide a complete, concise, and informative title. The full names of all authors must be provided, with complete affiliation including institutions and the Orcid number of each author. Only one corresponding author should be indicated with an asterisk and should always be the submitting author. The address should be concise and in English, including institution, postal code, city, state, and country. Do not translate laboratory, department, and university. Titles and positions should not be mentioned. This information is followed by the corresponding author’s email address.

The second page should contain a structured Abstract not exceeding 200 words, in a single paragraph, without references. The Abstract should outline the essential content of the manuscript, especially the results and discussion, highlighting the relevance of the main findings.

The Abstract should be followed by five to ten keywords. Note that essential words from the title should be repeated in the keywords.

Original articles should be divided into sections presented in the following order:

• Introduction
• Materials and Methods
• Results
• Discussion
• Acknowledgments
• Authors’ Contributions
• Conflict of Interest
• References
• Table and Figure Captions
• Supplementary Data (if applicable)

 

Materials, methods, and results should be clear and concise. The Discussion section should avoid extensive repetitions of the results and should end with some conclusions. This section may exceptionally be combined with results (Results and Discussion), but we recommend that authors consult the Editorial Board for a preliminary assessment.

Algae, fungi, and/or plant names should be written out in full in the abstract and again in the main text for each organism upon first mention, but the genus is only necessary for the first species in a list within the same genus (e.g., Hymenaea stigonocarpa and H. stilbocarpa). The authority of the scientific name (e.g., L., Mill., Benth.) is required only in the Materials and Methods section. Use the International Plant Names Index (www.ipni.org) for correct plant names. Cultivars or varieties should be added to the scientific name (e.g., Solanum lycopersicum ‘Jumbo’).

According to SciELO Brasil guidelines, authors are required to include in the Materials and Methods section a reference to voucher specimens or reference material, along with their respective voucher numbers, for all organisms involved or examined in the study. Reference material should be deposited or stored in registered collections accessible to the public. Failure to present voucher specimens will result in manuscript rejection. Voucher specimens of any organisms should preferably be deposited in collections that share their data through the Global Biodiversity Information Facility (GBIF).

The deposition of nucleotide sequences, including raw reads from high-throughput sequencing, is mandatory in repositories such as GenBank (http://www.ncbi.nlm.nih.gov/genbank), NCBI SRA – Sequence Read Archive (https://www.ncbi.nlm.nih.gov/sra), and/or others like Genome Sequence Archive (GSA – http://bigd.big.ac.cn/gsa).

When relevant, authors should cite in the Materials and Methods section all licenses, permissions, and authorizations for accessing genetic resources or traditional knowledge associated with genetic resources, collecting biological material inside and outside conservation units, protected areas, indigenous lands, quilombola territories, and other traditional peoples and communities’ territories, as well as registration in the National System for Management of Genetic Heritage and Associated Traditional Knowledge (SisGen), in the case of work with native species from Brazil. In cases where applicable, statements of approval from the ethics committee of the institution responsible for approving the research should be submitted as a separate file in the submission system.

Abbreviations should be avoided, except in common cases (see recent editions), and all terms, including scientific names, should be written out in full when used to start a sentence. Unconventional abbreviations should be explained upon their first mention.

 

Units of Measurement: Acta Botanica Brasilica adopts the International System of Units (SI). For volume, use cubic meters (e.g., 1 × 10^–5 m3) or liter (e.g., 5 μL, 5 mL, 5 L). For concentrations, use μM, μmol L^–1, or mg L^–1. For size and distance, use meters (cm, mm, μm, etc.) and be consistent throughout the manuscript.

Numbers up to nine should be written out in full unless they are measurements. All numbers above ten should be numerals unless they are at the beginning of sentences.

For Short Communications, it is important to note that the editorial guidelines applicable to original articles must be strictly followed. In general, the main difference between original articles and scientific notes lies in the absence of subsections in the text and the limited space for illustrations in the latter. Although it is possible to present figures and tables, it is important to respect the limit of five printed pages for the manuscript (supplementary material can be included if necessary). After the abstract (as described for original articles), the text should be presented in a single section, without subheadings, followed by acknowledgments and references.

Citations and References

For citations, the journal adopts a bibliographic format adapted from the American Psychological Association (APA) style, as outlined below. Citations in the text should take the form of Silva (2012) or Ribeiro & Furr (1975) or (Mayer & Wu, 1987a; b; Gonzalez, 2014; Sirano, 2014; Smith et al., 2018) and be arranged chronologically. Articles with three or more authors, even on the first mention, should be abbreviated with the first author’s name followed by et al., always italicized (e.g., Simmons et al., 2014). If two different authors have the same surname and the article has the same publication year, indicate the initials (e.g., JS Santos, 2003). Only refer to articles as ‘in press’ if they have been accepted for publication in a named journal; otherwise, use the term ‘unpublished data’, indicating the initials and surname of the person in question (e.g., RA Santos, unpublished data).

References should be arranged in alphabetical order according to the surname(s) of the author(s). When the same author(s) has/have two or more listed articles, these articles should be grouped in order of year. Letters ‘a’, ‘b’, ‘c’, etc., should be appended to the date of works with the same citation in the text. Provide the DOI of all articles, including those ‘in press’ and preprints, whenever possible.

In references, for articles with six authors or fewer, provide the names of all authors. For articles with seven authors or more, provide only the names of the first six authors, followed by et al. Citation of the DOI (Digital Object Identifier) is encouraged for all references for which it is available.

Acknowledgments should preferably be less than 80 words. Be concise: “We thank…” is preferred over “The present authors would like to express their gratitude to…”. Funding information should be included in this section, including sponsor names and contract numbers (if applicable), along with explanations of the role of these sources.

The following example should be followed:

We thank the Microscopy Center (UFMG) for providing equipment and technical support for experiments involving electron microscopy. We also thank J.S. Santos for their assistance with statistical analyses. This work was funded by a research grant from the National Council for Scientific and Technological Development – CNPq (identification number).

Authors’ Contribution

After the acknowledgments, authors should include a section specifying the contribution of each author to the work, following the taxonomy structure of the CRediT Contributor Roles (https://credit.niso.org/). The taxonomy is a framework that identifies and defines the different roles played by contributors in a project, providing a standardized way to recognize their contributions. For example, in the context of a research project, someone who primarily participated in conceptualization would have conceived the initial idea of the project, outlining its scope and objectives. Meanwhile, someone involved in data collection and organization would be responsible for Data Curation, ensuring the quality and accessibility of the data used. These roles, such as “Conceptualization” and “Data Curation,” among others listed, are essential for understanding who contributed in what way to the work performed. The taxonomy facilitates appropriate credit attribution to each contributor based on their specific responsibilities throughout the project.

Conflicts of Interest

Authors should include a section in the manuscript declaring no conflicts of interest (personal, scientific, commercial, political, or financial) in the submitted manuscript. Otherwise, a letter should be sent directly to the Editor-in-Chief.

Preparation of Figures, Tables, and Supplementary Material

Digital Assets

All figures (photographs, maps, drawings, graphs, diagrams, etc.) and tables should be cited in the text in ascending order. Figure citations in the text should appear in abbreviated form and uppercase (e.g., Fig. 1, Fig. 2A-D, Fig. 3A, Figs. 3A, 4C, Tab.1).

The maximum dimensions of individual figures should be 170 × 240 mm. The width of an individual component can be either 170 mm or 85 mm, without exception, while the height can be ≤ 240 mm. For continuous-tone images (e.g., photographs), provide TIFF files with 300 dpi. More complex drawings, such as detailed botanical illustrations, will not be redrawn and should be provided in TIFF files at 600 dpi.

Grouping related graphs or images into a single figure (a panel) is strongly encouraged. When a block of illustrative material consists of multiple parts, each part should be labeled with sequential uppercase letters in the order of their citation in the text (A, B, C, etc.). The letters identifying individual images should be placed within white circles in the lower right corner. To separate grouped images, authors should insert white frames (1mm thick). Individual images (not grouped into panels) should be identified with sequential Arabic numerals in the order of their citation in the text (Fig. 1, Fig. 2, Fig. 3, etc.), presented in the same manner, with letters identifying individual images, as described for panels above. The number identifying a grouped figure (e.g., Fig. 2) should not be inserted into the panel but referenced only in the figure caption and text (e.g., Fig. 2A-C). Scale bars, when necessary, should be positioned in the lower right corner of the figure. The units of the scale bar should be provided at the end of the figure caption or, when a figure contains multiple scale bars with different units, above each bar. Details within a figure can be indicated with arrows, letters, or symbols, as appropriate.

Due to our policy of inclusion for colorblind and visually impaired individuals, we recommend the use of a perceptually uniform color map, such as viridis or cividis; avoid red, especially in combination with green; check your figure in grayscale or fully desaturated; choose a color palette that works for everyone; use features such as shapes and line textures to eliminate color ambiguity.

Tables should be preceded by titles, indicated with sequential Arabic numerals (Table 1, 2, 3, etc.; do not abbreviate). Tables should be created using the Table function in Microsoft Word™. Columns and rows should be visible, although no dark lines should be used to separate them. Horizontal rules should only be used at the top (below the title) and bottom (below the final row) of the table. Do not use fills, shading, or colors in tables. All tables should be submitted in a single file.

Supplementary Documents

When appropriate, supplementary data may be submitted as Supplementary Files, which will be published online and made available as links. This may include figures, tables, or other additional materials necessary to fully document the research contained in the article or to facilitate readers’ understanding of the work. Supplementary materials are linked to the main article page and can be cited using the same DOI as the article.

Supplementary Materials should be provided in .doc or .docx format appropriate for text and tables and .tiff format at 300dpi for figures and graphs. The full title of the article and the names of the authors should be included in the header. All supplementary figures and tables should be referenced in the body of the manuscript as “Table S1” and/or “Figure S1”.

Acta Botanica Brasilica intends to maintain Supplementary Materials files but does not guarantee their permanent availability. The journal reserves the right to remove Supplementary Materials from a published article in the future.

In line with scientific principles of openness, transparency, and reproducibility, Acta Botanica Brasilica encourages the sharing of all datasets used in the analysis, including analysis scripts, other codes, methods, and additional materials in open online repositories such as SciELO data, Figshare, and OSF, if they cannot be published within the article itself. This information should be indicated in the manuscript.
