ABI5 (BOLC102_C04P013790.1_BOLC102_V1) — Brassica oleracea

Summary

BoABI5 (BOLC102_C04P013790.1) on cabbage chromosome 4 encodes a bZIP transcription factor of the BZIP46-like family, with DNA-binding transcription activator activity and additional annotated molecular functions including protein phosphatase binding, SUMO transferase activity, and aromatic aminotransferase activity. This gene is associated with regulation of abscisic acid anabolism, TOR signaling, nitrate assimilation, salicylic acid metabolism, and responses to pH and calcium ions. It is linked to numerous agronomically relevant traits including seed set percent, endosperm storage protein content, protein content, inflorescence length, leaf elongation rate, whole plant size, vegetative to reproductive phase transition, plant male sterility, lignin biosynthesis, phosphorus uptake, and sensitivities to alkali soil, copper, magnesium, manganese, nitrogen, nitrate, and far red light. Studies of related genes in other species connect the family to abscisic acid responsiveness, seed longevity, desiccation tolerance, salt stress tolerance, water use efficiency, and resistance to viruses.
