Mechanism of Drought Tolerance in Plants Using Trichoderma spp.

Jane Chepsergon | Dr. Lizzy Mwamburi ^[2] | Maritim Kipkemboi Kassim

Abstract: Drought is a major stress limiting the increase in the demand for food crops yet the world population is rapidly growing. Trichoderma spp. has been found to be associated with almost all natural ecosystems. They exist either in the rhizosphere or on plant roots. They form a symbiotic relationship with the host plant. In the existence of the relationship, the proteome and transcriptome of plants change as a consequence of the interaction of Trichoderma metabolites or plant colonization. Alleviation of damage by reactive oxygen species (ROS), Water-use efficiency and Secretion of phytohormonal analogues are the three mechanisms employed by the fungi in enhancing plant growth under drought stress. Globally, studies clearly reveal that, the use of Trichoderma spp. under drought stress can effectively augment plant growth.
