Cytokinin response factor 1 acts as a negative regulator of cytokinin-mediated developmental pathways in Arabidopsis.

Planta - 11 Mar 2026

Mandal Drishti, Chakraborty Swarnavo, Nag Chaudhuri Ronita

Abstract excerpt

MAIN CONCLUSION: CRF1 functions as a negative regulator of cytokinin signaling in Arabidopsis at least in part by antagonizing ARR12-dependent SHY2 transactivation, thereby influencing primary root growth, rosette development, and leaf senescence. Cytokinin Response Factors (CRFs) are members of the AP2/ERF family of transcription factors that act downstream of the two-component cytokinin signaling pathway to...
