Trichoderma applications on strawberry plants: a proteomic analysis of treated vs control plants

Many Trichoderma spp. are successful plant beneficial microbial inoculants due to their ability to act as biocontrol agents with direct antagonistic activities to phytopathogens, and as biostimulants capable of promoting plant growth. This work investigates the effects of treatments with three selected Trichoderma (strains T22, TH1 and GV41) to strawberry plants on the productivity and proteome of the formed fruit. Proteomic analysis of fruits,harvested from the plants previously treated with Trichoderma and control plants was performed by using a TMT-based protein quantification strategy. Bioinformatic analysis of the differential proteins accumulation in fruits, harvested from the treated plants, revealed a central network of interacting molecular species, that demonstrated the modulation of different plant physiological processes following the microbial inoculation.
