LEC1 — Brassica napus

Summary

BnLEC1 (DARMORV10_A09P42780.1) on chromosome A09 of oilseed rape encodes a CCAAT-box-binding transcription factor of the NF-YB/HAP3 family, with DNA-binding transcription activator activity, chromatin binding and protein heterodimerization activity. The gene is associated with the positive regulation of fatty acid anabolism, lipogenesis, starch anabolism, proanthocyanidin anabolism, protein synthesis, and the TCA cycle. It is linked to photomorphogenesis, blue light signaling, long-day flowering regulation, fruit development, and regeneration. Associations include seed growth and development, seed maturation, embryo development, seed oil biosynthesis, storage protein accumulation, desiccation tolerance, and fatty acid biosynthesis. The gene is also connected to leaf curling, chlorosis, starch and protein content, root morphology, abscisic acid sensitivity, disease tolerance, and salt tolerance. Studies of related genes in other species link the family to somatic embryogenesis, seed oil content, seed weight, fatty acid composition, seed dormancy, flowering time, and pathogen resistance.
