AFB2 — Arabidopsis thaliana

Summary

AT3G26810, also known as AFB2 (auxin signaling F-box 2) in Arabidopsis thaliana, encodes an F-box domain-containing protein and exhibits auxin receptor activity, auxin binding, NEDD8 transferase activity, and ubiquitin-like protein transferase activity. The gene is associated with plant growth, cell activation, SCF complex assembly, and responses to nitrate, cyclopentenone, and IBA stimulus. AFB2 is linked to numerous traits including seedling cotyledon size, root shape, root branching, root hair density, adventitious root number, leaf margin serration, leaf curling, leaf vein morphology, floral organ number, petal size, phototropism, shade avoidance, heat stress response, osmotic stress tolerance, biomass yield, and molybdenum content. The protein localizes to the nuclear SCF complex and ubiquitin ligase complex, and participates in auxin signaling pathways involving AUX/IAA degradation and ARF regulation.
