Abstract:

Jasmonic acid (JA) and its methyl ester are plant-specific signaling molecules that play important roles in many aspect of plant growth and development processes, such as mechanical damage resistance, metabolism regulation and induction of defense-related gene expression. In this review, we summarize the regulatory mechanism for JA biosynthesis and the current knowledge of JA signaling pathway, and finally, the problems remained to be studied and the possible research directions in this field are proposed.

Key words: jasmonic acid; biosynthesis; regulation; signaling pathway
