Latest results indicate that the invasion of pathogenic microorganisms can activate the jasmonic acid defense mechanism of plant hosts. At the same time, pathogenic microorganisms can sense jasmonic acid and manipulate the jasmonic acid signal transduction pathways of plant hosts, thus enhancing their own pathogenicity. In this review, we first briefly describe the biosynthesis and signalling pathways of jasmonic acid, followed by an overview of the research progress on the multiple functions of jasmonic acid in the interaction of various pathogenic bacteria, fungi, and viruses with plant hosts. These findings will provide insights in understanding the roles of jasmonic acid in the interaction between pathogenic microorganisms and plant hosts.展开更多
