植物激素与芥子油苷在生物合成上的相互作用

植物激素在植物的生长发育中起着关键性作用，芥子油苷是一类重要的次生代谢物质。植物激素与芥子油苷之间存在复杂的相互作用。生长素与吲哚类芥子油苷在生物合成上存在着相互作用。植物防卫信号分子与芥子油苷之间也存在相互作用，茉莉酸强烈诱导吲哚类芥子油苷生物合成相关基因CYP7982和CYP7983的表达，从而诱导吲哚-3-甲基芥子油苷和N-甲氧吲哚-3-甲基芥子油苷等吲哚类芥子油苷的生成，水杨酸和乙烯则能轻度诱导4-甲氧吲哚-3-甲基芥子油苷的生成。植物防卫信号转导途径相互作用以精细调节不同种类吲哚类芥子油苷的生成。

Interactions between Phytohormones and Second Metabolite Glucosinolates

Phytohormones play essential role in plant development, and glucosinolate is a group of important secondary metabolite, the complex interactions exist between phytohormones and glucosinolates at the level of biosynthesis. Aunxin and indole glucosinolates interact at the level of biosynthesis and metabolism. Plant defense signaling molecules can induce the biosynthesis of specific glucosinolates. Jasmonic acid highly induces the expression of indole glucosinolates biosynthetic genes CYP79B2 and CYP79B3, and thus leads to an increase in total indole glucosinolate contents. Specifically, the biosynthesis of indole-3-ylmethyl glucosinolate and N-methoxyindole-3-ylmethyl glucosinolate were highly induced after JA treatment, whereas 4-methoxyindole-3-ylmethyl glucosinolate was slightly induced by salicylic acid and ethylene. The cross talks exist between different plant defense signal transduction pathways to regulate the biosynthesis of indole glucosinolates.
