MTR_7G104480 — Medicago truncatula

Summary

MTR_7G104480 (MtABI5, also known as MtGIA1 or MtDPBF1) on barrel medic chromosome 7 encodes a bZIP transcription factor of the BZIP46-like family with DNA-binding transcription activator activity and additional annotated molecular functions including protein phosphatase regulator activity, SUMO transferase activity, and Ca2+/CaM-dependent kinase activity. The gene is associated with seed-related processes such as dormancy, acquisition of desiccation tolerance and seed longevity, regulation of seed maturation, and regulation of abscisic acid anabolism. It is linked to numerous agronomic traits including seed set percent, endosperm storage protein content, inflorescence length, leaf elongation rate, whole plant size, plant male sterility, and responses to abiotic stresses such as aluminum, cadmium, copper, and nitrogen sensitivity. Studies of related genes in other species connect the family to abscisic acid signaling, seed germination, salt stress tolerance, and virus resistance.
