In this study, we used as a biological model to report the role of StuA in phytopathogenic fungi. Our findings indicated that StuA is required for toxin (ACT) biosynthesis and fungal virulence. In addition, StuA physically interacts with PacC. Disruption of or led to decreased expression of seven toxin biosynthetic genes (ACCT) and toxin production. PacC could recognize and bind to the promoter regions of and . Our results revealed a previously unrecognized (StuA-PacC)→ACTTR module for the biosynthesis of ACT in , which also provides a framework for the study of StuA in other fungi.
在本研究中，我们以 为生物模型，报道了 StuA 在植物病原真菌中的作用。研究结果表明，StuA 是毒素（ACT）生物合成和真菌毒力所必需的。此外，StuA 与 PacC 发生物理相互作用。破坏 或 导致七个毒素生物合成基因（ACCT）和毒素产生的表达下降。PacC 可以识别并结合 和 的启动子区域。我们的结果揭示了一个以前未被识别的（StuA-PacC）→ACTTR 模块，用于 ACT 在 中的生物合成，这也为在其他真菌中研究 StuA 提供了一个框架。
