光肩星天牛咬食复叶槭后植物体内诱导的信号传导
The induced signal transduction in Acer negundo after feeding-damaged by Anoplophora glabripennis
【摘要】 研究与分析表明光肩星天牛咬食复叶槭后,植物体内茉莉酸(JA)含量和脱落酸(ABA)含量在短时间内增加,而水杨酸含量则减少,JA和ABA是抵抗伤害反应的信号传递物质,因此JA和ABA的增加表明该植物存在防御信号传导.
【Abstract】 The levels of jasmonic acid(JA) and abscisic acid(ABA) increased,while the level of salicylic acid (SA) decreased after ashleaf maple(Acer negundo L.) was damaged by Anoplophora glabripennis.JA and ABA were the signal chemicals to defend the damage.The increased content of JA and ABA showed that the signal transduction was induced after feeding-damage.
