GBF4 — Camelina sativa

Summary

CsGBF4 (CSA14G005080) on Camelina sativa chromosome 14 encodes a bZIP transcription factor, possessing sequence-specific DNA binding and transcription cis-regulatory region binding activities. The gene is associated with fatty acid and lipid metabolism, particularly linoleic and linolenic acid content, as well as seed coat development, seed size, and lignin anabolism. It has been linked to abscisic acid (ABA) signaling and sensitivity, drought tolerance, salinity response, and blue light response. Localisation evidence places the product in the nucleus, cytosol, and cytoplasm. Studies of related genes in other species link the family to ABA sensitivity, osmotic stress tolerance, and salinity tolerance. CsGBF4 is also associated with vascular tissue morphology and root morphology traits, and with flowering under drought stress.
