茉莉酸及其衍生物是衍生自亚麻酸的氧脂素信号化合物。茉莉酸在自然和黑暗诱导的衰老过程中积累，但这些化合物的增加对于这些衰老过程的开始或进展并不重要。在这里，我们报告说，在自然和黑暗诱导衰老的茉莉酸水平的增加不会触发茉莉酸信号。此外，我们提供的证据表明，茉莉酸的生产可能会导致暗诱导衰老过程中的膜周转。
Jasmonic acid and derivatives are oxylipin signaling compounds derived from linolenic acid. Jasmonates accumulate during natural and dark-induced senescence but the increase in these compounds is not essential for the initiation or progression of these senescence processes. Here we report that during natural and dark-induced senescence the increase in jasmonate levels does not trigger jasmonate signaling. Furthermore we provide evidence that jasmonate production might result from membrane turnover during dark-induced senescence.
