摘要:

稻瘟菌(Magnaporthe oryzae)是典型的植物致病菌,其侵染过程依赖多种信号通路参与调控,包括环化腺苷酸(cAMP)信号通路、丝裂原活化蛋白激酶(mitogen-activated protein kinase,MAPK)信号通路和Ca2+信号通路。最新研究发现,除了cAMP信号通路和MAPK信号通路,Ca2+信号通路在稻瘟菌的生长发育、孢子萌发、侵染结构形成和致病性方面也具有重要作用。结合这些信号通路及其相关基因和蛋白研究,综述了调控稻瘟菌致病性相关发育的信号传递分子机理,旨在为稻瘟菌致病机理的研究提供新的线索。

Abstract:

Magnaporthe oryzae is a typical plant pathogen. Its infection processes are mediated by a variety of signal pathways including cAMP, mitogen-activated protein kinase (MAPK) and Ca2+ signal pathways. The latest research discovered that apart from cAMP and MAPK signal pathways, Ca2+ signal pathway also played an important role in M. oryzae hyphal growth, sporulation, germination, appressorium formation and phytopathogenicity. The molecular mechanism of infection processes related signal transduction of M. oryzae were reviewed based on studying these signal pathways and the related genes and proteins, aiming at providing new clues for investigating M. Oryzae pathogenisis.

Key words: Magnaporthe oryzae, Ca2+ signaling pathway, calmodulin, Ca2+/calmodulin- dependent protein kinase, calcineurin
