Abstarct: Over the years, jasmonates (JAs) have become recognized as one of the main plant hormones that regulate stress responses by activating defense programs and the production of specialized metabolites. High JA levels have been associated with reduced plant growth, supposedly as a result of the reallocation of carbon sources from primary growth to the biosynthesis of defense compounds. Recent advances suggest however that tight regulatory networks integrate several sensing pathways to steer plant metabolism, and thereby drive the trade-off between growth and defense. In this review, we discuss how JA influences primary metabolism and how it is connected to light-regulated processes, nutrient sensing and energy metabolism. Finally, we speculate that JA, in a conceptual parallelism with adrenaline for humans, overall boosts cellular processes to keep up with an increased metabolic demand during harsh times.

近年来，茉莉酸已成为公认的主要的植物激素之一，它通过激活防御程序和特异的代谢物调控逆境反应。较高的茉莉酸水平与植物生长减慢有关，这可能是由于碳源从初级生长重新分配到防御化合物的生物合成 。然而，最近研究表明，紧密的调控网络整合几个感知途径来引导植物新陈代谢，从而推动生长和防御之间的权衡。该综述讨论了茉莉酸是如何影响初级代谢和光照调控过程、营养感知和能量代谢联系在一起的。最后，该综述推测在 茉莉酸在概念上与人类肾上腺素类似，总体上促进了细胞过程，以满足逆境时期的新陈代谢需求。
