Abstract
Trichoderma spp. are isolated from various ecological habitats and known to produce various enzymes and secondary metabolites with agriculture and industrial importance. Trichoderma spp. are applied as biological control agents (BCAs) to battle a wide array of plant diseases. The function of BCA is enabled through involvement of various mechanisms (mycoparasitism, release of antibiotic metabolites or enzymes, nutrient competition) and direct interactions of Trichoderma spp., plants, or pathogenic organism (induced plant immunity or resistance). The secondary metabolites or enzymes of Trichoderma are known to directly inhibiting the plant pathogenic organisms, while its elicitors trigger the plant immunity toward biotic stress. Trichoderma elicitors are directly or indirectly combat the plant disease either inhabiting the plant pathogenic microbes or activating the plant immunity related pathways, although several studies presented the mechanism of Trichoderma elicitors and plant interactions. Still the complete mechanism of Trichoderma elicitors in contest to BCAs is uncovered. Moreover, it is essential to gain the current status of Trichoderma elicitors and BCA potentials for the development of future research. Therefore, the present chapter reviews the recent updates on elicitor proteins from Trichoderma in BCAs and summarizes the key points and future directions.
