Abstract:

Higher plants often encounter environmental stresses during their life cycle. Plants have developed a powerful inducible defense system to defend against a diversity of attackers. The plant defense system depends largely on the inducible expression of a vast array of defense genes. The expression of many frontline defense response genes is controlled by jasmonates. As a vital defense-related hormone, jasmonates mediate plant defense against herbivorous insects and necrotrophic pathogens. Meanwhile, jasmonates have also emerged as an essential growth regular to control diverse aspects of plant development process, such as stamen maturation, root growth, anthocyanin accumulation and senescence. We have used molecular, genetic, biochemical and genomic approaches to study molecular basis for jasmonate action in regulation plant development and defense.
