LysM effectors play a relevant role during the plant colonization by successful phytopathogenic fungi, since they enable them to avoid either triggering of defense mechanisms or their attack effects. Tal6, protein from Trichoderma atroviride, is capable binding complex chitin. However, until now its biological function not completely known, particularly participation in plant-Trichoderma interactions. We obtained T. atroviride Tal6 null mutant and overexpressing strains determined played this Trichoderma-plant interaction mycoparasitism. effector protects hyphae chitinases chitin fungal cell wall, increases fungus mycoparasitic capacity, modulates activation system. These results show that beneficial fungi also employ improve association with plants.

Phytopathogenic fungi decrease crop yield and quality cause huge losses in agricultural production. To prevent the occurrence of diseases insect pests, farmers have to use many synthetic chemical pesticides. The extensive these pesticides has resulted a series environmental ecological problems, such as increase resistant weed populations, soil compaction, water pollution, which seriously affect sustainable development agriculture. This review discusses main advances research on plant-pathogenic terms their pathogenic factors cell wall-degrading enzymes, toxins, growth regulators, effector proteins, fungal viruses, well application biocontrol agents for plant diseases, weeds. Finally, further studies resources with better effects can help find new beneficial microbial that control diseases.

Because of the need to provide food for growing population, agricultural activity is faced with huge challenge counteracting negative effects generated by adverse environmental factors and diseases caused pathogens on crops, while avoiding pollution due excessive use agrochemicals. The exploitation biological systems that naturally increase plant vigor, preparing them against biotic abiotic stressors also promote their growth productivity represents a useful viable strategy help face these challenges. Fungi from genus Trichoderma have been widely used in agriculture as biocontrol agents because mycoparasitic capacity ability improve health protection phytopathogens, which makes it an excellent symbiont. mechanisms employed include secretion effector molecules secondary metabolites mediate beneficial interaction plants, providing tolerance stresses. Here we discuss most recent advances understanding this opportunistic symbiont agent promoter.

Abstract Fusarium stalk rot (FSR) caused by graminearum (FG) significantly affects the productivity of maize grain crops. Application agrochemicals to control disease is harmful environment. In this regard, use biocontrol agent (BCA) an alternative agrochemicals. Although Trichoderma species are known as BCA, selection host-pathogen specific essential for successful field application. Hence, we screened a total 100 isolates against FG, selected harzianum (CCTCC-RW0024) greenhouse experiments and studied its effect on changes rhizosphere microbiome FSR. The strain CCTCC-RW0024 displayed high antagonistic activity (96.30%), reduction (86.66%), biocontrol-related enzyme gene expression. root colonization was confirmed eGFP tagging qRT-PCR analysis. Pyrosequencing revealed that exogenous inoculation in increased plant growth promoting acidobacteria (18.4%), decreased 66% also growth. addition, metabolites could interact with pathogenicity related transcriptional cofactor FgSWi6, thereby contributing inhibition.
