Two recently duplicated maize NAC transcription factor paralogs are induced in response to Colletotrichum graminicola infection.

ABSTRACT:

Background

NAC transcription factors belong to a large family of plant-specific transcription factors with more than 100 family members in monocot and dicot species. To date, the majority of the studied NAC proteins are involved in the response to abiotic stress, to biotic stress and in the regulation of developmental processes. Maize NAC transcription factors involved in the biotic stress response have not yet been identified.

Results

We have found that two NAC transcription factors, ZmNAC41 and ZmNAC100, are transcriptionally induced both during the initial biotrophic as well as the ensuing necrotrophic colonization of maize leaves by the hemibiotrophic ascomycete fungus C. graminicola. ZmNAC41 transcripts were also induced upon infection with C. graminicola mutants that a
