MAPK Pathways Coordinate Stress Adaptation by Mobilizing Specialized Gene Modules in Entomopathogenic Fungus Beauveria bassiana

Shuaishuai Huang, Hailing Fan, Chenhua Zhu, Mei Li et autres

Mitogen-activated protein kinase (MAPK) cascades are critical for fungal development, stress adaptation. and virulence. However, their dynamic and stress-specific regulatory networks in entomopathogenic fungi remain largely unresolved. This study systematically investigates the roles of all three key MAPKs—BbHog1, BbSlt2, and BbMpk1—in insect …

The siderophore-iron transporter BbMirB is required for the fungal pathogen Beauveria bassiana to repress insect immunity and promote proliferation during colonization of hemocoel

Chenhua Zhu, Qi Liu, Yuhan Chen, Fangfang Tian et autres

ABSTRACT Nutritional immunity plays a vital role in limiting the proliferation of microbial pathogens in vertebrates and invertebrates. During coevolution with their hosts, pathogens have developed tactics to counteract the host nutritional immunity by acquiring iron via s iderophore- i ron t …

The AreA Nitrogen Catabolite Repression Activator Balances Fungal Nutrient Utilization and Virulence in the Insect Fungal Pathogen Beauveria bassiana

Zhibing Luo, Qiyan Chen, Su Yufeng, Shasha Hu et autres

In many fungi, the AreA GATA-type transcription factor mediates nitrogen catabolite repression affecting fungal development and, where applicable, virulence. Here, we investigated the functions of AreA in the fungal entomopathogen and plant endophyte Beauveria bassiana using knockdown of gene expression. The antiAreA …
