摘 要:

褪黑素是一种色氨酸衍生物。植物中褪黑素可参与植株的生长与发育, 生物与非生物胁迫应答, 成熟与衰老。根据近年来研究进展, 本文重点对植物中褪黑素的生物合成途径及其调控植物响应干旱、盐害、高温和重金属胁迫的机理进行归纳总结; 同时, 对今后植物中褪黑素可能的研究方向进行预测。

Abstract:

Melatonin is a derivative of tryptophan. It is involved in plant growth and development, biotic and abiotic stress response, and plant maturity and senescence. This paper mainly presents the research progress of plant melatonin biosynthetic pathway and the mechanism of melatonin-regulated plant stress responses to drought, salt, high temperature and heavy metal in recent years. Meanwhile, we propose the possible research direction of plant melatonin in future.

Key words: melatonin; stress response; biosynthetic pathway; abiotic stress
