Abstract: Being sessile,plants are always challenged by a variety of environmental stresses,including herbivorous insect attack and microbial pathogen infection. To defend themselves against these stresses,plants have evolved sophisticated and highly regulated defense system,such as activation of biosynthesis of plant hormones that regulate defense-related gene expression and secondary metabolite production. Intriguingly,many herbivorous insects and microbial pathogens have been found to employ distinct strategies to evade,overcome,or even manipulate plants' defense system to facilitate their exploitation of host plants. Jasmonate,an important class of lipid-derived plant hormone,regulates multiple aspects of plant growth and development and also plays crucial roles in plant responses to diverse biotic and abiotic stresses. In recent years,the biosynthesis,signal transduction and biological functions of jasmonate have been extensively studied,and significant progresses have been achieved. In this review,we provide a overview of jasmonate biosynthesis regulation and signaling transduction pathway. We also discuss the mechanisms of jasmonate action in plant biotic stress responses and summarize the various strategies used by herbivorous insects or microbial pathogens to hijack jasmonate pathway. This review would be helpful for an in-depth understanding of jasmonate-mediated interactions of plants with pathogenic organisms.

Key words: jasmonate, plant, biotic stress, plant-pathogen interaction
