简介:jasmonic酸(JA)小径是昆虫folivory导致的主要signal-transduction小径。在jasmonate小径(18:0或16:0-oxylipin线路)影响的变异的植物被学习在在Arabidopsis位于导致的防卫下面的互连的signal-transduction小径上估计JA和它的oxylipin中介12-oxophytodienoic酸(OPDA)和dinor-OPDA(dnOPDA)的效果。我们oxylipinjasmonatesdnOPDA,OPDA和JA举办的数据表演在防卫发信号的不同角色在由咀嚼咬毛虫Pierisrapae喂以后导致了。Jasmonic酸,并且不OPDA或dnOPDA,主要发信号混合物为防卫相关的基因LOX2(Lipoxygenase2)的正式就职被要求,OPR3(12-Oxophytodienoatereductase3),ACX1(Acyl-CoAoxidase1)并且PAL1(本氨基丙酸ammonia-lyase1)。监视PAL1抄本层次清楚地在P之上显示出JA的那累积。喂的rapae导致水杨酸酸小径的正式就职。而且,JA是为P要求的主要发信号混合物。防卫相关的基因HPL1的导致rapae的表示(Hydroperoxidelyase1)。jasmonatednOPDA也影响HPL分支的正式就职,还它的效果对JA的效果对抗。我们这些jasmonates可以被用来调整Arabidopsis的数据表演导致草食动物的回答以从oxylipin小径的HPL分支。
