Abstract

Phytopathogenic fungi are a group of organisms that cause diseases in plants through disturbances in their cellular metabolism. They have major impacts on agriculture, accounting for 8 - 40% of the losses in world agricultural production. Meanwhile, microalgae synthesize a wide variety of allelopathic chemicals and can be used for different biocidal purposes, including antifungal. The objective of this study was to review the antifungal activity of microalgal extracts and their compounds against phytopathogenic fungi. This systematic review of the literature was conducted using SciELO, PubMed, and Periódicos Capes (Scopus). Following the search, 25 articles published in English and Portuguese were selected. Several publications will be recorded from 2015 to 2022. Eight microalgal phyla (Bacillariophyta, Chlorophyta, Cyanobacteria, Haptophyta, Miozoa, Ochrophyta, Prasinodermatophyta, and Rhodophyta) were detected, with Chlorophyta and Cyanobacteria having the highest number of registered publications. The most tested species of phytopathogenic fungi were Aspergillus niger and Botrytis cinerea. Regarding the categorized inhibition classification for the assays, high inhibition was observed in 31.26% of the trials. Studies performed with cyanobacterial species showed a higher proportion of high inhibition (41.36%) of phytopathogens. Given the high degree of biodiversity of microalgae and their wide range of associated bioactive molecules, this is a vast field to explore for novel biopesticides with antifungal potential.

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.
