ABSTRACT

A novel homolog of laeA, a global regulatory gene in filamentous fungi, was identified from Pyricularia oryzae. A deletion mutant of the homolog (PoLAE2) exhibited lowered intracellular cAMP levels, and decreased appressorium formation on non-host surface; the decrease was recovered using exogenous cAMP and IBMX, indicating that PoLAE2 deletion affected the cAMP signaling pathway.

在稻瘟病菌中，laLAA同源物PoLAE2在腹膜形成和cAMP信号转导中的功能。

摘要

从稻瘟病菌中鉴定出一种新型的laeA同源物，一种全球性丝状真菌调控基因。同源物的缺失突变体（PoLAE2）显示出降低的细胞内cAMP水平，并减少了非宿主表面上的ress形成。使用外源性cAMP和IBMX恢复了下降，表明PoLAE2缺失影响了cAMP信号通路。
