LEC2 — Brassica oleracea var. botrytis

Summary

BoLEC2, the cauliflower (Brassica oleracea var. botrytis) gene on chromosome 7, encodes a B3 DNA-binding domain transcription factor of the LEC2-like family. It localises to the nucleus and cytoplasm and has DNA-binding and transcription factor activity. BoLEC2 is associated with the regulation of lipid metabolism, fatty acid anabolism, seed oilbody biogenesis, embryo development ending in seed dormancy, flower development, photoperiodism, flowering, ABA signalling and response, and positive regulation of auxin biosynthesis. It has been linked to numerous seed and embryo traits including seed oil, protein, starch and sucrose content, triacylglycerol accumulation, desiccation tolerance, germination, embryonic maturation, trichome formation, lateral root formation, cell dedifferentiation, gibberellin biosynthesis, and vernalisation memory. Related genes in other species connect the family to somatic embryogenesis, seed maturation, and triacylglycerol accumulation in leaves.
