Pathogenic fungi: leading or led by ambient pH?

abstract：:The fungus Parastagonospora nodorum is the causal agent of Septoria nodorum blotch of wheat (Triticum aestivum). The interaction is mediated by multiple fungal necrotrophic effector-dominant host sensitivity gene interactions. The three best-characterized effector-sensitivity gene systems are SnToxA-Tsn1, SnTox1-Snn1 ...
