TaPIMP2, a pathogen-induced MYB protein in wheat, contributes to host resistance to common root rot caused by Bipolaris sorokiniana

Abstract MYB transcription factors (TFs) have been implicated in various biology processes in model plants. However, functions of the great majority of MYB TFs in wheat (Triticum aestivum L.) have not been characterized. The soil-borne fungal pathogens Bipolaris sorokiniana and Rhizoctonia cerealis...
