ABI4 — triticum aestivum

Summary

TRAESCS1A02G223400 (TaABI4) on wheat chromosome 1A encodes an AP2/ERF domain-containing transcription factor with DNA-binding and transcription cis-regulatory region binding activity. It is associated with regulation of starch breakdown, triglyceride catabolic process, hexokinase-dependent signaling, retrograde response, and actin cytoskeleton organization. The gene has been linked to yield, seed protein content, endosperm storage protein content, seed color, anthocyanin content, photosynthetic rate, stomatal opening, flowering time, drought tolerance, low temperature stress response, oxidative stress response, disease tolerance, root growth and thickness, lateral root development, seedling growth, embryogenesis, and abscisic acid sensitivity. It is also associated with sugar signal transduction, feedback inhibition of photosynthesis, water use efficiency, cadmium accumulation, and gibberellin catabolism. The protein localizes to the nucleus, cytoplasm, plasmalemma, and endoplasmic reticulum.
