The plant floral scent methyl jasmonate (MeJA) has been identified as a vital cellular regulator that mediates diverse developmental processes and defense responses against biotic and abiotic stresses. The pleiotropic effects of MeJA have raised numerous questions about its regulation for biogenesis and mode of action. Characterization of the gene encoding jasmonic acid carboxyl methyltransferase has provided basic information on the role(s) of this phytohormone in gene-activation control and systemic long-distance signaling. Recent approaches using functional genomics and bioinformatics have identified a whole set of MeJA-responsive genes, and provide insights into how plants use volatile signals to withstand diverse and variable environments.
植物花香成分茉莉酸甲酯（MeJA）已被确认为一种重要的细胞调节因子，它介导多种发育过程以及对生物和非生物胁迫的防御反应。MeJA的多效性引发了许多关于其生物合成调控和作用模式的问题。茉莉酸羧基甲基转移酶编码基因的表征为这种植物激素在基因激活控制和系统性长距离信号传导中的作用提供了基本信息。最近使用功能基因组学和生物信息学的方法已经鉴定出了一整套MeJA响应基因，并为植物如何利用挥发性信号来抵御多样且多变的环境提供了见解。
