AFB2 — Pisum sativum

Summary

PsAFB2 (PSAT3G094360) on chromosome 3LG5 encodes an auxin signaling F-box protein with auxin receptor activity, auxin binding, IP6 binding, transcription cis-regulatory region binding, and DNA-binding transcription factor activity. It is associated with SCF-dependent proteasomal ubiquitin-dependent protein breakdown, auxin signaling, and regulation of jasmonic acid-mediated signaling. The gene is linked to lateral root morphogenesis, primary root development, geotropism, embryonic pattern specification, stamen development, vascular tissue pattern formation, defense response to insects, and responses to nitrate, red and far-red light, herbicides, and cyclopentenone. It localizes to the nucleus, cytoplasm, SCF complex, and plant-type vacuole. Associations include seedling cotyledon size, phototropism, adventitious rootless, petiole length, herbicide sensitivity, auxin sensitivity, flowering time, seed development, and abiotic stress response traits. Studies of related genes in other species link the family to auxin sensitivity, lateral root formation, salt and drought tolerance, and plant growth regulation.
