Abstract

Due to the significant ecological, economic, and medicinal potential of roncador (Mouriri guianensis Aubl.), it is essential to understand the genetic diversity and distribution of this species, especially as no study has been conducted on its genetic composition. Therefore, the study aimed to evaluate the genetic diversity and structure in natural populations of roncador using ISSR molecular markers. Genetic analyses were performed on roncador populations occurring naturally in the state of Mato Grosso, Brazil, in four locations: Rio Cuiabá (Barão do Melgaço), Rio São Lourenço (Poconé), and Rio Jauru (Cáceres) in the Pantanal Biome, and Rio Sepotuba (Cáceres) in the Amazon. For molecular characterization, eight ISSR primers were selected, resulting in 127 amplified fragments (98% polymorphism). AMOVA showed greater genetic diversity among populations (52%). The highest diversity indices were found for the Rio Jauru population (H=0.28; I=0.41, and P%=71.65). UPGMA clustering analysis formed five distinct genetic groups based on collection locations, while Bayesian analysis formed two groups according to biomes. Principal Coordinates Analysis corresponded with UPGMA and Bayesian clustering, isolating the Rio Sepotuba population (Amazon). ISSR molecular markers revealed genetic diversity among roncador individuals, highlighting population structuring among different collection locations and biomes, suggesting the importance of conserving native populations of the Amazon and Mato Grosso Pantanal.

Ethical Guidelines for Journal Publication

The Ciência e Natura journal is committed to ensuring ethics in publication and quality of articles. 

Conformance to standards of ethical behavior is therefore expected of all parties involved: Authors, Editors, Reviewers, and the Publisher.

In particular, 

Authors: Authors should present an objective discussion of the significance of research work as well as sufficient detail and references to permit others to replicate the experiments. Fraudulent or knowingly inaccurate statements constitute unethical behavior and are unacceptable. Review Articles should also be objective, comprehensive, and accurate accounts of the state of the art. The Authors should ensure that their work is entirely original works, and if the work and/or words of others have been used, this has been appropriately acknowledged. Plagiarism in all its forms constitutes unethical publishing behavior and is unacceptable. Submitting the same manuscript to more than one journal concurrently constitutes unethical publishing behavior and is unacceptable. Authors should not submit articles describing essentially the same research to more than one journal. The corresponding Author should ensure that there is a full consensus of all Co-authors in approving the final version of the paper and its submission for publication.

Editors: Editors should evaluate manuscripts exclusively on the basis of their academic merit. An Editor must not use unpublished information in the editor's own research without the express written consent of the Author. Editors should take reasonable responsive measures when ethical complaints have been presented concerning a submitted manuscript or published paper.

Reviewers: Any manuscripts received for review must be treated as confidential documents. Privileged information or ideas obtained through peer review must be kept confidential and not used for personal advantage. Reviewers should be conducted objectively, and observations should be formulated clearly with supporting arguments, so that Authors can use them for improving the paper. Any selected Reviewer who feels unqualified to review the research reported in a manuscript or knows that its prompt review will be impossible should notify the Editor and excuse himself from the review process. Reviewers should not consider manuscripts in which they have conflicts of interest resulting from competitive, collaborative, or other relationships or connections with any of the authors, companies, or institutions connected to the papers.
