AP2 — Camelina sativa

Summary

CsAP2 (CSA10G003930) on Camelina sativa chromosome 10 encodes a DNA-binding transcription factor with an AP2/ERF domain, also possessing transcription corepressor activity and protein homodimerization activity. The gene is associated with regulation of seed development, endosperm development, starch biosynthesis, and fatty acid elongation, as well as floral organ abscission, seed abscission, and specification of floral organ identity. It is linked to gibberellic acid homeostasis, wax anabolism, meristem maintenance, and the transition from vegetative to reproductive phase. Associations with seed mass, flowering time, root morphology, jasmonic acid content, and photoassimilate translocation have also been noted. The protein localizes to the nucleus, cytoplasm, and transcription regulator complex. Studies of related genes in other species link the family to floral meristem determinacy, ovule development, and seed quality traits.
