Role of the Global Fitness Regulator Genes on the Osmotic Tolerance Ability and Salinity Hazard Alleviation of Trichoderma asperellum GDFS 1009 for Sustainable Agriculture
Abstract:Velvet family proteins are global regulators of fungal growth and development. Here, we reported the role of Vel1 and Lae1 from T. asperellum in osmotic tolerance. Deletion of the Vel1 and Lae1 genes led to the retardation of vegetative mycelial growth under saline conditions. The strain carrying the overexpression locus of the Vel1 and Lae1 genes was highly resistant to oxidative stress by upregulating the enzymes and genes involved in antioxidant activity. Major physiological changes in the cell wall and vac… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
