主　　题：Phytopathogen Virulence factor Transcriptome reprogramming Agrochemical Pesticide Rice 

摘      要：Bacteria equipped with virulence systems based on highly bioactive small molecules can circumvent their host s defense *** employing this strategy are currently threatening global rice *** the present study,variations in the virulence of the highly destructive Barkholderiaplantarii were observed in different rice-producing *** environment-linked variation was not attributable to any known host-related or external ***-occurrence analyses indicated a connection between reduced virulence and 5-Amino-l,3,4-thiadiazole-2-thiol(ATT),a non-bactericidal organic ***,which accumulates in rice plants during metabolization of specific agrochemicals,was found to reduce virulence factor secretion by *** up to 88.8%and inhibit pathogen virulence by hijacking an upstream signaling *** assessment of the newly discovered virulence inhibitor resulted in mechanistic insights into positive effects of ATT accumulation in plant *** of virulence alleviation were deciphered by integrating high-throughput data,gene knockout mutants,and molecular interaction ***,a histidine protein kinase in a two-component system that regulates virulence factor secretion,is likely the molecular target antagonized by *** findings provide novel insights into virulence modulation in an important plant-pathogen system that relies on the host s metabolic activity and subsequent signaling interference.
