Therefore, this study aimed to elucidate the function of MYB50 under ABA signaling. Our experiments demonstrated that ABA treatment reduced MYB50 expression and promoted the degradation of MYB50 protein. This degradation alleviates the inhibitory effects of MYB50 on root growth. Furthermore, ABA differentially regulates MYB50 compared with ABI5, another key transcription factor involved in root growth under ABA signaling, suggesting that ABA uses distinct regulatory pathways for root growth.
