Trichoderma asperellum GD040 upregulates defense-related genes and reduces lesion size in Coffea canephora leaves inoculated with Colletotrichum cairnsense

Rui Wang et al.

Summary: Coffee anthracnose is a worldwide disease that has adversely affected coffee growers' profits. This study identified Colletotrichum cairnsense as a pathogen causing coffee anthracnose and discovered Trichoderma asperellum GD040 as an effective antagonist with strong inhibition and mycoparasitism abilities. The application of T. asperellum GD040 spore suspension through root irrigation effectively reduced lesion size on coffee leaves caused by C. cairnsense. Transcriptomic analysis revealed the up-regulation of 175 genes, including disease-resistance genes and genes associated with pathways such as plant-pathogen interaction and phenylpropanes biosynthesis, in coffee treated with T. asperellum GD040. Furthermore, qRT-PCR analysis demonstrated the significant up-regulation of key resistance genes and growth hormone synthesis-related genes in coffee leaves treated with T. asperellum GD040, indicating its potential for inducing host resistance against anthracnose. These findings provide valuable insights into the antagonistic mode and molecular mechanisms underlying Trichoderma-mediated control of coffee anthracnose.
