ABI4 — Brassica juncea

Summary

BJUB08G40920S (BjABI4) on chromosome B08 encodes a DNA-binding transcription factor with an AP2/ERF domain, capable of sequence-specific DNA binding, transcription cis-regulatory region binding, and protein complex binding. It is associated with regulation of triglyceride catabolic process, hexokinase-dependent signaling, retrograde response, plastid organization, cuticle anabolism, and actin cytoskeleton organization. The gene has been linked to numerous agronomic traits including yield, seed protein content, seed color, endosperm storage protein content, flowering time, lateral root number and length, root mass density, drought tolerance, oxidative stress response, low temperature stress tolerance, disease tolerance, ethylene sensitivity, anthocyanin content, stomatal opening, and petal morphogenesis. It localizes to the nucleus, cytoplasm, plasmalemma, and endoplasmic reticulum. Related genes in other species are linked to seed production, plant height, salt tolerance, triacylglycerol accumulation, seed vigor, and abscisic acid responsiveness.
