LEC2 — Brassica oleracea var. botrytis

Summary

BoLEC2, located on chromosome 5 of cauliflower (Brassica oleracea var. botrytis), encodes a LEC2-like protein with a B3 DNA-binding domain and DNA-binding transcription factor activity. It is associated with regulation of lipid metabolism, fatty acid anabolism, seed oilbody biogenesis, embryo development ending in seed dormancy, flower development, photoperiodism, flowering, ABA signaling, and positive regulation of auxin biosynthetic processes. The gene is linked to seed oil content, seed storage protein accumulation, triacylglycerol accumulation, seed desiccation tolerance, seed germination, and embryonic maturation. It is also associated with trichome formation, lateral root formation, cell dedifferentiation, and vernalization memory. Related genes in other species link the family to somatic embryogenesis, seed maturation, and triacylglycerol accumulation in leaves.
