摘要
Sclerotinia sclerotiorum is a destructive necrotrophic plant pathogen with global distribution. Although S. sclerotiorum has been studied extensively, substantial research on aspects of the pathogen's ability to cause disease is still needed. Bax inhibitor-1 protein functions as a suppressor of programmed cell death and is involved in the response to biotic and abiotic stress in animals, plants and yeast. In this study, we functionally characterized a putative Bax inhibitor-1 protein, Ss-Bi1, from S. sclerotiorum. Ss-Bi1 is predicted to contain a BAX inhibitor-1-like super family domain and shows significant homology with many BAX inhibitor-1 proteins. High expression levels of Ss-Bi1 were observed in hyphae under various stresses. Targeted silencing of Ss-Bi1 resulted in reduced virulence in host plants. Ss-Bi1 gene-silenced strains were more sensitive to heat stress and ER stress than the wild-type strain. The results suggest that Ss-Bi1 encodes a putative BAX inhibitor-1 protein that is required for full virulence of S. sclerotiorum. (C) 2015 Elsevier Ltd. All rights reserved.
