Abstract

Ustilaginoidea virens, which causes rice false smut (RFS), is one of the most detrimental rice fungal diseases and poses a severe threat to rice production and quality. Effectors in U. virens often act as a group of essential virulence factors that play crucial roles in the interaction between host and the pathogen. Thus, the functions of individual effectors in U. virens need to be further explored. Here, we found a small secreted hypersensitive response-inducing protein UVI_02019870 was highly conserved in fungi. Furthermore, we performed Y2H and BiFC assay to demonstrated UVI_02019870 interacted with OsCPL1, which was predicted as a chloroplast precursor to regulate chloroplast signaling pathways. Our data provide a theory for gaining an insight into the molecular mechanisms underlying the UVI_02019870 virulence function.
