ABI4 — Brassica juncea

Summary

BjABI4 (BJUB06G53030S) on Indian mustard chromosome B06 encodes a protein with an AP2/ERF domain that binds DNA and transcription cis-regulatory regions. It is associated with numerous biological processes including hexokinase-dependent signaling, retrograde response, regulation of triglyceride catabolic process, cuticle anabolism, actin cytoskeleton organization, and anisotropic cell growth. The gene has been connected to a wide range of agronomically important traits such as yield, seed protein content, seed color, anthocyanin content, flowering time, disease tolerance, drought tolerance, oxidative stress response, low temperature stress response, lateral root number and length, root thickness, stomatal opening, petal length, and trichome morphology. It localizes to the nucleus, cytoplasm, plasmalemma, and endoplasmic reticulum. Studies of related genes in other species link the family to seed maturation, oil accumulation, seed vigor, and abscisic acid responsiveness.
