LEC2 — Brassica napus

Summary

BnLEC2 (DARMORV10_C05P27150.1) on chromosome C05 of oilseed rape encodes a B3 DNA-binding domain transcription factor with DNA-binding and transcription cis-regulatory region binding activity. This gene is associated with a wide range of seed development processes, including embryogenesis, seed oilbody biogenesis, fatty acid anabolism, lipogenesis, and positive regulation of auxin biosynthetic process. It is linked to seed oil content, seed weight, seed size, seed storage protein accumulation, triacylglycerol accumulation, seed desiccation tolerance, and seed maturation. Additional associations include pollen maturation, fruit development, flowering time, ABA signaling, and regeneration. The gene product localises to both the nucleus and cytoplasm. Studies of related genes in other species connect the family to somatic embryogenesis, seed maturation, and triacylglycerol accumulation in leaves.
