ABI3 — Brassica oleracea var. botrytis

Summary

BoABI3 (BOLND125_C03P049490.1) on cauliflower chromosome 3 encodes a B3 DNA-binding domain protein of the LEC2-like family, annotated with phytochrome binding, Hsp90 binding, transcription coactivator activity, and ubiquitin-protein transferase activity. The gene is associated with positive regulation of seed maturation, cellular response to gibberellin stimulus, regulation of lipid metabolism, and retrograde response. It is linked to numerous agronomic traits including seedling vigor, seed set percent, vegetative vigor, water stress response, photoperiod sensitivity, iron content, cadmium concentration, phosphorus uptake, aphid response, temperature stress response, aluminum response, and male sterility. Studies of related genes in other species connect the family to seed development, ABA sensitivity, drought tolerance, seed longevity, oil accumulation, desiccation tolerance, and resistance to Leptosphaeria maculans.
