新型植物激素——系统素

Systemin:A New Plant Hormones

系统素最初是指在番茄叶片中发现的与植物防卫反应相关的1种含18个氨基酸的多肽信号,现已成为植物伤害生理研究领域的热点。概述了植物系统素的结构特点、前体及其在伤信号转导中的作用等方面的研究进展,并展望了系统素今后的研究方向。

Systemin is initially a peptide signal with 18 amino acids related to plant defense responses found in tomato leaf.It has become the research focus of physiological damages.The research progress on the structure of systemin,precursor and roles in wound signal transduction is introduced,and the directions for further study are suggested.
