ABI3 — Daucus carota subsp. sativus

Summary

DcABI3 (DCAR_004706) on carrot chromosome 1 encodes a LEC2-like protein with a B3 DNA-binding domain, annotated with sequence-specific DNA binding, transcription coactivator activity, and phytochrome and Hsp90 binding. It is associated with positive regulation of seed maturation, cellular response to gibberellin stimulus, far red signaling, negative gravitropism, and regulation of triglyceride catabolism, actin polymerization, and cell shape. The gene is linked to traits including petal length, gibberellic acid content, seedling vigor, seed set percent, photoperiod sensitivity, water stress response, cadmium concentration, and male sterility. Related genes in other species are associated with seed development, ABA sensitivity, drought tolerance, freezing tolerance, oil accumulation, seed longevity, and flowering time.
