The target gene of tae-miR164, a novel NAC transcription factor from the NAM subfamily, negatively regulates resistance of wheat to stripe rust.

ABSTRACT: microRNA (miRNA) participates in various physiological and biochemical processes in plants by regulating corresponding target genes. NAC [NAM (no apical meristem), ATAF (Arabidopsis transcription activation factor) and CUC (cup-shaped cotyledon)] transcription factors, usually as the targets of miR164, play important roles in the regulation of plant development and responses to abiotic and biotic stresses. In a previous study, the target gene of tae-miR164 in wheat was sequenced through degradome sequencing. In this study, we isolated the full-length cDNA of the candidate target gene, which is a NAC transcription factor gene in the NAM subfamily, and designated it as TaNAC21/22 after bioinformatics analysis. The interaction between TaNAC21/22 and tae-miR164 was confirmed experimentally thr
