“…(named LG by authors) were tested against this same fungus and LP was the most potent among the tested compounds, with EC50 of 5058 mg L -1 , 4872 mg L -1 and 3617 mg L -1 , after 48 h, 72 h and 120 h, respectively. In contrast, the LG was the lowest active, with EC50 of 13982 mg L -1 , 9449 mg L -1 and 5635 mg L -1 after 48 h, 72 h and 120 h against the same fungus [42].…”

Lectins were discovered first in plants and later in other living things, and nowadays it is known that they are present in almost all many life forms. These proteins can bind to specific carbohydrates, which make them perform a number of biological activities and can be used as tools in the study of glycoconjugate structures present on the cell surface, being effective in medical research. Plant lectins, leguminosae lectins particularly, are among the most studied plant proteins. They are very versatile molecules, which show several interesting biological properties. Thus, the present paper reviewed the advances about the leguminosae lectins biological properties studies in the last ten years, taking into account their possible applications in the fields of Clinical Microbiology, Pharmacy and Cancerology through a search in the electronic databases, providing opportunity to exchange information about the theme. Leguminosae lectins can neutralize pathogenic organisms, be they viruses, prokaryotes and eukaryotes, in addition carcinogenic cells, besides decreasing oxidative stress, conditions which increases the possibility of alternative substances for the design of new drugs to be used in current therapeutic, expanding the possibilities of diseases cure. HIGHLIGHTS Leguminous lectins are proteins found in various parts of leguminous plants. Leguminous lectins are versatile in the carbohydrate binding specificity. Leguminous lectins have antimicrobial, antioxidant and antiproliferative features. Leguminous lectins are promising molecules for the design of new drugs.

“…Available references indicated that Phaseolus vulgaris lectin is effective against some pathogenic bacteria and fungi such as Staphylococcus aureus, Streptococcus mutants, Pseudomonas aeruginosa and Candida albicans (Hamed, Einas et al, 2017). Also, Glycine max lectin is effective against some pathogenic fungi such as Fusarium oxysporum and Rhizoctonia solani (Mohsen, Soad et al , 2018). While Moringa oleifera lectin has antifungal effect against some fungi such as Aspergillus niger, A. flavus , Candida albicans (Ayirezang et al, 2020 andSantos et al, 2021).…”

Eight lectins, four of which were used in pure forms, i.e. lectins of white bean seeds, red bean (Adzuki) seeds, pea seeds and lentil seeds. The other four were used in crude forms for the first time, i.e. lectins of white bean seeds, soybean seeds, moringa seeds and orchid tree seeds. All plant lectins tested in vitro against the growth of three fungi that cause strawberry fruit-rot, i.e. Botrytis cinerea, Corynespora cassiicola and Alternaria alternata. The crude lectin exhibited high ability to inhibit radial growth of these fungi compared with the pure lectin, this may be due to the presence of other effective compounds besides lectins in the extract. There was congruence in the general effect of both tested crude and pure lectins on fungal growth, where Botrytis growth was the most affected by any used lectin. Moringa crude lectin was high efficient in inhibiting the radial growths with 80.00%, 71.33% and 53.00%, respectively. Postharvest spraying of strawberry fruits with crude lectins succeeded in reducing soft-rot severity compared to control under laboratory conditions outside refrigerators. Fungal treating in vitro with crude lectins was consistent with postharvest fruit treating, where moringa crude lectin showed high soft-rot inhibition efficiency (70.40, 66.28 and 30.93%). The results indicated possibility of exploiting crude plant lectins to discourage postharvest fruit-rot and it is tempting to repeat the experiment on plants in the greenhouse and then in the field if the necessary quantities of lectins are available when lectin production gene is transferred to a fast-developing microorganism.

“…Chitin in cell wall of fungi might be the target of antifungal lectins. Several plant lectins have antifungal activities against Fusarium species (Mohsen et al, 2018). Nikitina et al (2017) recently reviewed lectins from mycelia and fruiting bodies of basidiomycetes.…”

Background: Biological control for cereal diseases caused by mycotoxigenic fungi is part of the alternative methods to be developed to secure food and feed production, recognizing the negative effects these fungi have on crop yield and their potential production of mycotoxins. Objective: Update recent knowledge about the potential of mushroom-forming fungi as biological control agents of mycotoxigenic fungi species, acting as antagonists on crop debris, as source of active extracts with antifungal and/or antimycotoxin properties and as detoxifying agents in solid-state fermentation processes of contaminated cereals. Methods: A literature review of the published works was carried out, the main topics were analyzed, as well as the species with the greatest potential of biological control agents of mycotoxingenic fungi. Results and conclusions: Mushroom forming fungi could be used as antagonists on crop debris or grains, as sources of active extracts with antifungal and/or antimycotoxin properties, and as detoxifying agents. An integration of these three potentials gives rise to an environment friendly process for production of both safe grains and edible mushrooms.
