ABI3 — Brassica napus

Summary

BnABI3 (ABI3, SIS10) on chromosome C03 of oilseed rape encodes a B3 DNA-binding domain protein of the LEC2-like family. The gene product is associated with phytochrome binding, Hsp90 binding, transcription coactivator activity, and sequence-specific DNA binding. It is associated with the positive regulation of seed maturation, seed growth, cellular response to gibberellin stimulus, and proanthocyanidin anabolism. Associations with agronomic traits include seed width and length, fruit shattering, seed coat color, seedling and vegetative vigor, oleic acid and protein content, phosphorus uptake, and cadmium concentration. Related genes in other species are linked to seed development, abscisic acid responsiveness, oil accumulation, seed longevity, desiccation tolerance, and resistance to geminivirus.
