In recent years, it has been revealed that ATA is a new signaling molecule and has effects on microbial physiology. In this review, we first briefly outlined the relationship between ATA and tryptophan synthesis in Escherichia coli and Saccharomyces cerevisiae. We then summarized the metabolic network and biological functions of ATA in Pseudomonas aeruginosa, as well as the progress of ATA in regulating the physiology of Ralstonia solanacearum. Finally, we summarized the latest results describing the roles of ATA in other microorganisms and proposed that ATA may play a role in interkingdom communication.展开更多

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
