Ste12 transcription factor homologue CpST12 is down-regulated by hypovirus infection and required for virulence and female fertility of the chestnut blight fungus Cryphonectria parasitica.

Abstract excerpt

A putative homologue of the Saccharomyces cerevisiae Ste12 transcription factor was identified in a series of expressed sequence tag-based microarray analyses as being down-regulated in strains of the chestnut blight fungus, Cryphonectria parasitica, infected by virulence-attenuating hypoviruses. Cloning of the corresponding gene, cpst12, confirmed a high level of similarity to Ste12 homologues of other...
