摘要:

丝裂原活化蛋白激酶(MAPK)是一类高度保守的丝氨酸/苏氨酸(Ser/Thr)蛋白激酶,广泛存在于真核生物中级联反应途径。植物MAPK具有相对保守的11个亚结构域,均为Ser/Thr蛋白激酶发挥其催化作用所必需的元件,其表达受活性氧、一氧化氮、激素等调控。MAPK可磷酸化多种底物,包括转录因子、蛋白激酶和细胞骨架相关蛋白等,在调控植物响应逆境(盐分、干旱、极端温度、重金属等)胁迫中起重要作用。本研究对植物MAPK家族的发现、分类与结构、调控机制及其响应各种非生物胁迫等方面的研究成果加以综述,并对未来研究方向进行展望,以期为农作物抗逆性遗传改良提供理论依据和基因资源。

Abstract:

Mitogen-activated protein kinase (MAPK) is a highly conserved serine/threonine (Ser/Thr) protein kinase, occurring widely in eukaryotic intermediate reaction pathways. Plant MAPK has 11 relatively conserved sub-domains, which are all essential elements for Ser/Thr protein kinase to play its catalytic role, and its expression is regulated by reactive oxygen species, nitric oxide and hormones. MAPK phosphorylates a variety of substrates including transcription factors, protein kinases and cytoskeleton related proteins, and plays an important role in regulating plant response to abiotic stresses (salt, drought, extreme temperature, and heavy metals). In this review, we summarize the results of research on the discovery of plant MAPK family members, their structure and classification, regulatory mechanisms, and their roles in response to various abiotic stresses. We also propose directions for future research. The information in this review provides a theoretical basis and identifies genetic resources for the genetic improvement of crops to produce new, stress-resistant varieties.
