与其他真核生物一样，有丝分裂原活化蛋白激酶级联反应在真菌病原体对宿主和环境信号的响应中发挥重要作用。一般来说，丝裂原活化蛋白激酶（MAPK）是通过丝裂原活化蛋白激酶（MEK）磷酸化保守的苏氨酸-x-酪氨酸（TXY）基序激活的，而丝裂原活化蛋白激酶（MEKK）又激活了丝裂原活化蛋白激酶（MEKK）。出芽酵母酿酒酵母有5条MAPK通路，分别调控交配、侵入性生长、细胞壁完整性、渗透调节和子囊孢子形成。除了子囊菌发生特异性MAPK （sporulation-specific mitogen-activated protein kinase, Smk1）外，其他的酵母MAPK在植物致病性子囊菌中保守表达，调控不同的感染和发育过程，这是本文综述的重点。在植物致病担子菌中，MAPKs仅在麦氏黑穗病菌中得到了很好的表征。
Like in other eukaryotic organisms, mitogen-activated protein (MAP) kinase cascades play important roles in response to host and environmental signals in fungal pathogens. In general, mitogen-activated protein kinase (MAPK) is activated by phosphorylation at the well-conserved threonine-x-tyrosine (TXY) motif by mitogen-activated protein kinase (MEK), which is in turn activated by mitogen-activated protein kinase (MEKK). The budding yeast Saccharomyces cerevisiae has five MAPK pathways that regulate mating, invasive growth, cell wall integrity, osmoregulation, and ascospore formation. Except for ascosporogenesis-specific MAPK sporulation-specific mitogen-activated protein kinase (Smk1), other yeast MAPKs are conserved in plant-pathogenic ascomycetes to regulate different infection and developmental processes, which is the focus of this review. In phytopathogenic basidiomycetes, MAPKs have only been well characterized in Ustilago maydis.
