Tuber mustard BjuFIP gene negatively regulates plant sensitivity to abscisic acid.

ABSTRACT: Tuber mustard (Brassica juncea var. tumida) is an economically important vegetable crop, with its tumorous stem serving as the primary raw material for Fuling mustard production. However, multiple abiotic stress during growth often leads to significant yield losses. As a vital hormone for plant stress adaptation, abscisic acid (ABA) plays essential roles in stress responses. However, despite the agricultural importance of tuber mustard, no studies have yet reported on ABA related functions in this crop. In this study, we identified the F-box protein gene BjuFIP as a key regulator in ABA signaling. BjuFIP was ubiquitously expressed across all tissues and significantly upregulated by ABA treatment.
