ABI4 — Brassica juncea

Summary

BJUA05G05240S (BjABI4) on Indian mustard chromosome A05 encodes a protein with an AP2/ERF domain that binds DNA and transcription cis-regulatory regions. It is associated with hexokinase-dependent signaling, retrograde response, regulation of triglyceride catabolic process, cuticle anabolism, and ascorbate biosynthesis. The gene is linked to numerous agronomic traits including yield, seed protein and storage protein content, seed color, iron content, lateral root number and length, root mass density, flowering time, petal length and morphology, trichome morphology, stomatal opening, ethylene sensitivity, anthocyanin content, and responses to low temperature, oxidative stress, nematode damage, and far-red light. It is also associated with phenotypes such as drought tolerance, ABA sensitivity, sugar signaling, germination, seedling growth, embryogenesis, and cadmium accumulation.
