摘要
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.
