Abstract excerpt
Drought is a major constraint on global wheat productivity. Although the phytohormone abscisic acid (ABA) is a well-established regulator of drought responses, its regulatory mechanisms in wheat remain unclear. Here, we identify the abscisic acid-, stress- and ripening-induced (ASR) transcription factor TaASR4-3D as a negative regulator of drought tolerance in wheat. Constitutive overexpression of TaASR4-3D...
