ABI4 — Brassica oleracea var. botrytis

Summary

BoABI4, located on cauliflower chromosome 3, encodes a protein with an AP2/ERF domain that binds DNA and protein complexes. This gene is associated with the regulation of diverse biological processes including triglyceride catabolism, hexokinase-dependent signaling, actin cytoskeleton organization, plastid organization, cuticle anabolism, and the retrograde response. It localizes to the nucleus, cytosol, plasma membrane, and endoplasmic reticulum. BoABI4 is linked to numerous agronomically important traits such as yield, seed protein and endosperm storage protein content, seed color, anthocyanin content, flowering time, lateral root number and length, root mass density, drought tolerance, low temperature and oxidative stress responses, ethylene sensitivity, and disease tolerance. Studies of related genes in other species connect the family to seed production, plant height, salt tolerance, triacylglycerol accumulation, and seed vigor.
