CgNis1's Impact on Virulence and Stress Response in <i>Colletotrichum gloeosporioides</i>.

ABSTRACT: Pepper anthracnose caused by Colletotrichum gloeosporioides infection is an important fungal disease and represents a serious threat to pepper yield and quality. At present, the pathogenic molecular mechanism of C. gloeosporioides is not very clear. In our study, we characterized the function of C. gloeosporioides CgNis1, a homolog of Magnaporthe oryzae MoNis1. We found that the ∆Cgnis1 mutant reduced the growth rate and was defective in conidiation. Although the rate of appressorium formation was unaffected, the germ tube was found to be abnormal. CgNis1 was shown to be involved in the H₂O₂ stress response and maintaining cell membrane permeability. The pathogenicity assays performed in this study indicated that the deletion of CgNI
