TaARR1, a cytokinin response regulator gene in Triticum aestivum, is essential in plant N starvation tolerance via regulating the N acquisition and N assimilation

Plant N starvation response is closely associated with the N signaling components that involve transduction of the low-N cues. In this study, we functionally characterized TaARR1, a cytokinin (CK) response regulator gene in Triticum aestivum, in mediating the N starvation adaptation in plants. TaARR1 harbors two conserved domains specified by plant ARR family members; subcellular localization analysis indicated its target onto nucleus after...
