ABI4 — Brassica juncea

Summary

BJUA03G38780S (BjABI4) on chromosome A03 of Indian mustard encodes a protein with an AP2/ERF domain that binds DNA and protein complexes. The gene is associated with regulation of triglyceride catabolism, hexokinase-dependent signaling, retrograde response, cuticle anabolism, ascorbate biosynthesis, and actin cytoskeleton organization. It localizes to the nucleus, cytosol, plasma membrane, and Arp2/3 complex. BjABI4 is linked to numerous agronomic traits including yield, seed protein and storage protein content, seed color, iron content, flowering time, lateral root number and length, root mass density, root thickness, petal length and morphology, trichome morphology, stomatal opening, and responses to ethylene, far-red light, low temperature, oxidative stress, and nematode damage. It is also associated with drought tolerance, ABA biosynthesis and sensitivity, sugar signaling, germination, seedling growth, embryogenesis, and disease tolerance.
