The journal considers contributions that present the results of original research in genetics, molecular biology, evolution and related scientific disciplines. Manuscripts presenting methods and applications only, without an analysis of genetic data, will not be considered.
It is a fundamental condition that submitted manuscripts have not been published or are not under consideration for publication elsewhere. With the acceptance of a manuscript for publication, the publishers acquire full and exclusive copyright for all languages and countries.
Manuscripts considered in conformity with the scope of the journal, as evaluated by the Editor, are reviewed by an Associate Editors and two or more external reviewers. Acceptance by the Editor is based on the quality of the work as substantial contribution to the field and on the overall presentation of the manuscript.
The official abbreviation for Genetics and Molecular Biology is Genet. Mol. Biol.
GMB articles published since 2009 are also indexed at PubMed Central and available in full text version at: http://www.ncbi.nlm.nih.gov/pmc/journals/1440/.
Back issues of earlier titles (Brazilian Journal of Genetics and Revista Brasileira de Genética) are hosted at GMB’s own site: http://www.gmb.org.br
Membership to the Brazilian Society of Genetics entitles subscription to Genetics and Molecular Biology.
For nonmembers and institutions, the annual subscriptions rates (four issues/year) are informed at the journal’s website http://www.gmb.org.br.
Submission of papers
1. Manuscripts have to be submitted through our online submission platform:
2. For submission the following instructions must be observed:
Failure to adhere to these guidelines can delay the handling of your contribution and manuscripts may be returned before being reviewed.
Special attention should be given to the structuring of the manuscript and correct language usage. These are important factors in the smooth running of the editorial and peer-review process, and can result in faster publication.
3. Categories of Contribution
The following elements must start on a new page and be ordered as they are listed below:
a) The Title Page must contain: a concise and informative title; the authors’ names (first name at full length); the authors’ institutional affiliation, including department, institution, city, state or province, and country; different affiliations must be indicated with superscript Arabic numbers; a short running title of up to 35 characters (including spaces); up to five key words; the corresponding author’s name, full postal, email address and ORCID ID.
b) The Abstract must be a single paragraph that does not exceed 200 words and summarizes the main results and conclusions of the study. It should not contain references.
c) The text must be as succinct as possible. Text citations: articles should be referred to by authors’ surnames and date of publication; citations with two authors must include both names separated by “and”; in citations with three or more authors, name the first author and use et al. List two or more references in the same citation in chronological order, separated by semi-colons. When two or more works in a citation were published in the same year, list them alphabetically by the first author surname. For two or more works by the same author(s) in a citation, list them chronologically, with the years separated by commas. (Example: Freire-Maia et al., 1966a, 1966b, 2000). Only articles that are published or in press should be cited. In the case of personal communications or unpublished results, all contributors must be listed by initials and last name (et al. should not be used). Numbers: In the text, numbers nine or less must be written out except as part of a date, a fraction or decimal, a percentage, or a unit of measurement. Use Arabic numerals for numbers larger than nine. Do not start a sentence with an Arabic numeral. Binomial Names: Latin names of genera, species and infraspecific taxa must be printed in italics; we also recommend to present names of orders or families in the Title and/or when first mentioned in the text. URLs for programs, data or other sources should be listed in the Internet Resources Section, immediately following the References Section, not in the text.
The text includes the following elements:
Introduction - Description of the background that led to the study.
Material (or Subjects) and Methods - Details relevant to the conduct of the study. Statistical methods should be explained at the end of this section.
Results - Undue repetition in text and tables should be avoided. Statistical analyses should be presented as complete as possible, i.e. not only P-values should be shown, but also all other test variables required for full appreciation of the results. Comments on relevance of results are appropriate but broader discussion should be part of the Discussion section.
Discussion - The findings of the study should be placed in context of relevant published data. Ideas presented in other publications should not be discussed solely to make an exhaustive presentation.
Some manuscripts may require different formats appropriate to their content.
d) The Acknowledgments must be a single paragraph that immediately follows the discussion and includes references to grant support.
e) Conflict of Interest: Any possible conflict of interest must be disclosed here. If there is none, please state: The authors declare that there is no conflict of interest that could be perceived as prejudicial to the impartiality of the reported research.
f) Authors Contributions: The contributions of each author must be specified here; identify authors by their initials. The style of this section may be as follows:
<author initials> conceived and the study, <author initials> conducted the experiments (detail if necessary), <author initials> analyzed the data, <author initials> wrote the manuscript, <author initials> (other contributions if applicable), all authors read and approved the final version.
In case of doubts concerning contribution definitions, we suggest to consult the CRediT taxonomy at https://casrai.org/credit.
g) The References Section: Only articles that are published or in press should be included in this section. Works submitted for publication but not yet accepted, personal communications and unpublished data must be cited within the text. “Personal communication” refers to information obtained from individuals other than the authors of the manuscript being submitted; “unpublished data” refers to data produced by at least one of the authors of the manuscript under consideration. Works of restricted circulation (e.g., theses not available in public databases, congress abstracts not published in regular journals or public databases) should not be listed in this section.
References must be ordered alphabetically by the first author surname; references with the same first author should be ordered as follows: first, as single author in chronological order; next, with only one more co-author in alphabetical order by the second author; and finally followed by references with more than two co-authors, in chronological order, independent of the second author surnames. In references with more than 10 authors only the first ten should be listed, followed by et al. Use standard abbreviations for journal titles as suggested by NCBI (http://www.ncbi.nlm.nih.gov/journals/) or Thomson Reuters Web of Science.

i) Tables: Formats for tables are Word or RTF in Windows platform. They must be prepared with the table tool (do not use space bar or tabulator) and must be numbered consecutively in Arabic numerals). A concise title should be provided above the table. Each column should have a title in the box head. Footnotes typed directly below the table should be indicated in lowercase superscript letters. Tables that are to appear in the printed version must be saved in Word format and not as figures, so that they can later be fitted during typesetting. Each table must be saved and uploaded as a separate file.
j) Figures: Formats for figures are TIFF or JPEG. They must be numbered consecutively using Arabic numerals. Figures in Word, PowerPoint or Excel format cannot be published. Only sequence data can be presented in Word format. Journal quality reproduction will require resolution yielding 300 dpi for grayscale and color figures. These resolutions refer to the output size of the file, that being the size in which it will appear printed in the journal; if it is anticipated that images will be enlarged or reduced, the resolutions should be adjusted accordingly. Figures composed of several elements should be sent as a single panel, obeying the print size definitions of the journal (single or two columns width). Scanned figures should not be submitted. Color illustrations are accepted and will be reproduced free of chrge in the electronic and printed versions. Figure legends must be included at the end of the main text file and should be typed on a new page. When uploading, identify each illustration by the first author name and the number of the respective figure. Each figure/panel must be saved and uploaded as a separate file.
k) Nomenclature: Taxonomic names should be in accordance with current international standards. For rules concerning gene names and gene symbols, please see separate Instruction form.
l) Sequences may appear in text or in figure. DNA, RNA and protein sequences equal to or greater than 50 units must be entered into public databases and accession numbers must be provided upon acceptance of the article. Failure to do so will inadvertently delay publication.
m) Data access: reference should be made to availability of detailed data and materials used for reported studies.
n) Ethical issues: Reports of experiments on live vertebrates must include a statement in the text that the institutional review board approved the work and the protocol number must be provided. For experiments involving human subjects, authors must also include a statement that informed consent was obtained from all subjects. If photos or any other identifiable data are included, a copy of the signed consent must be uploaded during manuscript submission. In any case, a letter (in English) indicating the approval by the respective Ethics Committee must be included in the submission. The letter should be preferentially Institutional and should confirm the protocol number of the approval.
o) Supplementary Material: Data that the authors consider of importance for completeness of a study, but which are too extensive to be included in the main text, can be submitted as Supplementary Material, in a separated file, but together with the main paper. In case a manuscript contains such material, it should be appropriately identified within the text file. Supplementary material in tables should be identified as Table S1, Table S2, etc., in case of figures they should be named accordingly, Figure S1, Figure S2. In addition, a list of this material should be presented at the end of the manuscript text file, containing the following statement:
3.2 Short Communications
Short Communications present brief observations that do not warrant full-length articles. They should not be considered preliminary communications. They should be 15 or fewer typed pages in double spaced 12-point type, including literature cited, include an Abstract no longer than five percent of the paper’s length, but no further subdivision, with introduction, material and methods, results and discussion in a single section and without headers. Up to four items (tables and/or figures) may be submitted. The title page and reference section format is that of a full-length Research Article. For Supplementary Material see instructions in item 3.1.n
3.3 Genome Insight
Genome Insight is for focused papers, usually of approximately 1500 words (up to four tables or figures), that publish new genome data as they become submitted to GenBank. This section is the premier forum to deliver that information directly to the genome community in a rapid and efficient publication of the genome. Data must be related to a complete (or nearly complete) and fully annotated genome for prokaryote or viruses, but a draft may be accepted for an eukaryote genome. While the focus of Genome Insight is necessarily involved in novel sequences, the manuscript must contain specifically novel biological, evolutive, biotechnological and/or metabolic insights revealed by data. The work may provide comparative analyses of previously published genomes that contain a substantial and novel insight of broadest biological and genetic significance.
Submitted manuscript must contain an abstract, which should be a brief report on the organism as well as its relevance and the main insight revealed by the genome. The text (approximately 1500 words- excluding abstract, references and acknowledgements) should not contain subdivisions, but must contain the rational for the selection of such organism as well as organism information (including taxonomy, natural habitat, phylogenetic position, eventual pathogenicity, symbiotic, biotechnological use, etc), methodology (genome sequencing and assembly; reference number at GenBank), genome relevance (which should indicate the main insights revealed by the data analysis and main conclusions. Acknowledgements and References (up to 20 references) headings should be included. Figure Legends should be provided at the end of the manuscript.
Metagenome, transcriptome as well as epigenome data may also be considered for publication, but prior submission of the abstract to the Editor is necessary.
Note: The title page, abstract and reference section format is that of a full-length Research Article. For Supplementary Material see item 3.1.n. in our Instructions to Authors.
3.4 Letters to the Editor
Relate or respond to recent published items in the journal. Discussions of political, social and ethical issues of interest to geneticists are also welcome in this form.
3.5 Review Articles
Review Articles are welcome. The Editor must be contacted prior to submission. Please, provide an Abstract and a list of your recent publications in the area.
3.6 Book Reviews
Publishers are invited to submit books on Genetics, Evolution and related disciplines, for review in the journal. Aspiring reviewers may propose writing a review.
3.7 History, Story and Memories
These are accounts on historical aspects of Genetics relating to Brazil.
4. Articles accepted for publication
Once an article is accepted, the Editorial Office will send it to copy editor for language and technical corrections. If major corrections were proposed, the manuscript with the highlighted corrections will be returned to the corresponding author for approval. The final version approved by the authors must be free of any text/correction markings when returned to the Editorial Office.
After typesetting, page proofs will be sent to the corresponding author. Changes made to page proofs, apart from typesetting errors, will be charged to the authors. Notes added in proof require Editorial approval.
Together with the proofs, a form of consent to publish and transfer of copyright is sent to the corresponding author, who will have sign this form, also on behalf of any co-authors, and send it by e-mail to the Editorial Office.
5. Availability of articles and deposition in databases
Article copies are provided as PDF-files. Authors may deposit these in their personal or institutional homepage, as well as in public databases.
6. Publication charge
