摘要:

促分裂素原活化蛋白激酶(mitogen-activated protein kinases,MAPK、MPK 或MK)级联是一种广泛存在于真核生物中的信号传导途径。同动物和酵母类似,植物细胞的MAPK 级联也是由MAPKKK (MEKK, MKKK),MAPKK (MEK,MKK),MAPK 三个级别的激酶对其下游蛋白的磷酸化构成的,最终对细胞生长、发育及抗性等过程中的效应分子进行调控。本文介绍了番茄目前的测序情况,以及番茄(Lycopersicon esculentum)MAPK(LeMAPK,LeMPK)的研究进展,根据MAPK 序列在进化过程中的保守性,用模式植物拟南芥(Arabidopsis thaliana)MAPK(AtMAPK,AtMPK)基因序列在番茄的转录序列中搜索,得到18 个LeMAPK 条目,其中两条是新的LeMAPK,并与AtMAPK 进行比对和归类。

Abstract:

The plant mitogen-activated protein kinases (MAPK) pathwaqys transduce a large variety of external signals, leading to a wide range of cellular responses, including growth, differentiation, stress reactions. In this review, we emphasized recent findings on the MAPK involvement related to stress tolerance in tomato (Lycopersicon esculentum MAPK, LeMAPK). According to the conservation of the MAPK sequences in different plants, we blasted the candidate LeMAPKs with the Arabidopsis (Arabidopsis thaliana) MAPK (AtMAPK, AtMPK) sequences and got 18 LeMAPKs with two new sequences. The sequences of LeMAPKs and AtMAPKs were alignmented. In addition, the potential LeMAPKs were primarily documented by informatic analysis, which were divided into five groups based on the phylogenetic analysis.
