Uncovering the role of ABI2 as a key regulator of flowering time in Arabidopsis.

Plant signaling & behavior - 31 Dec 2026

Ali Akhtar, Zareen Shah, Park Junghoon, Yun Dae-Jin

Abstract excerpt

Abscisic acid (ABA) is a fundamental regulator of plant development, growth, and drought adaptation, and it modulates the transition to flowering. However, the molecular mechanisms by which ABA delays flowering remain unclear. Recently, ABA INSENSITIVE 2 (ABI2), a core component of the ABA signaling pathway, was reported to positively regulate floral transition in Arabidopsis. The expression of floral repressors...
