摘要
促分裂原活化蛋白激酶(mitogen-actived protein kinase,MAPK)是一类受胞外刺激、通过MAPK级联反应(MAPKKK-MAPKK-MAPK)而激活的丝氨酸/苏氨酸蛋白激酶。MAPK级联途径是真核生物中广泛存在且高度保守的信号转导途径,通过蛋白质磷酸化作用将上游信号级联放大传递至下游应答分子。该途径在植物应对各种生物与非生物胁迫以及激素信号转导过程中起关键作用。本文着重介绍MAPK级联途径激酶结构特点及其信号转导途径在园艺作物逆境胁迫中的应答反应,以期为该领域的相关研究提供参考。
Mitogen-activated protein kinase （MAPK） is one kind of serine/threonine protein kinase, which acti- vated by extracellular stimulation through the MAPK cascade （MAPKKK-MAPKK-MAPK）. MAPK cascade pathway widely exist in eukaryotes organism and highly conserved. They participate in plant responses to vari- ous biological stress, abiotic stress and hormone signal conditions through the protein phosphorylation signal cascade amplifier to downstream response. This paper focuses on the structural characteristics of MAPK cas- cade kinase structure in plants and its response of signal transduction pathway under adversity stress in horti- cultural crop. The purpose is to provide some references for relevant researches in this field.
