摘要
反式-2-己烯醛是绿色植物释放的一种小分子挥发性物质,在调节植物生长发育和抵抗各种环境胁迫中发挥重要作用。已有研究表明,反式-2-己烯醛可抑制植物根系生长,具有较高的抑菌和抗虫活性,也可以作为植物间的"信使"来传递防御信号。该文系统综述了反式-2-己烯醛的生物合成、代谢途径及其在生物胁迫防御反应中的重要作用,提出了研究中存在的问题及未来的研究方向和建议,以期为深入揭示反式-2-己烯醛的作用机理提供参考。
As a small molecule volatile compound released by green plants,trans-2-hexenal plays a vital role in regulating plant growth and resistance to various environmental stresses.Studies have shown that trans-2-hexenal exhibits obvious inhibition on growth of plant root,and defense against bacterial infection and herbivorous feeding.Furthermore,it also displays a‘messenger’role in transmitting defense signals among plants.This paper reviewed trans-2-hexenal biosynthesis,metabolism pathway and its important role in defense response to biotic stress,also discussed the current problems in this research field and suggestions for future research,which would be helpful to illustrate defense or growth mechanism in plant response to trans-2-hexenal.
