摘　　要：长素的信号转导是一个复杂的网络系统,在信号的感知上,除了存在ABP1介导的膜上感知途径外,还有其他的感知途径。G蛋白参与诱导生长素信号的胞内传递,生长素信号转导的第二信使包括离子型第二信使、磷酯酶A2、脂活化蛋白激酶、MAPK和PINOIND等。AUX/IAA蛋白的泛素化降解在生长素反应中发挥关键性作用,ARF和AUX/IAA蛋白相互作用调节生长素响应基因的转录。Auxin signal transducation is a complex net-work system. There might exist other routes for auxin perception, besides the well-known ABP1 mediated perception pathway on the membrane. The G protein is involved in inducing the transfer of auxin signal in the cell, and the secondary messengers of auxin signaling include H+-ATPase, phospholipase A2, lipid-activated protein kinase, mitogen-activated protein kinase(MAPK) and the protein kinase PINOIND. The degradation of AUX/IAA protein by ubiquitination plays essential role in auxin response, and the interaction between ARF and AUX/IAA protein regulates the transcription of auxin-response genes.
