Comprehensive analysis of pathogen-responsive wheat NAC transcription factors: new candidates for crop improvement.

ABSTRACT: Wheat NAC (TaNAC) transcription factors are important regulators of stress responses and developmental processes. This study proposes a new TaNAC nomenclature and identified defense-associated TaNACs based on the analysis of RNA-sequencing datasets of wheat tissue infected with major fungal pathogens. A total of 146 TaNACs were pathogen-responsive, of which 52 were orthologous with functionally characterized defense-associated NACs from barley, rice, and Arabidopsis, as deduced via phylogenetic analysis. Next, we focused on the phylogenetic relationship of the pathogen-responsive TaNACs and their expression profiles in healthy and diseased tissues. Three subfamilies ("a," "e," and "f") were significantly enriched in pathogen-responsive TaNACs, of which the majority were responsive to at le
