GBF4 — Camelina sativa

Summary

CsGBF4 (CSA17G007050) encodes a bZIP transcription factor with sequence-specific DNA binding and transcription cis-regulatory region binding activities. In Camelina sativa, this gene is associated with seed coat development, fatty acid and lipid metabolism, glucosinolate metabolism, lignin anabolism, and blue light response. It has been linked to abscisic acid (ABA) signaling, including upregulation of ABA-mediated signaling and response to ABA, as well as activation of salinity response and upregulation of response to thirst. Associations with drought tolerance, abscisic acid sensitivity, seed size, linoleic and linolenic acid content, root and vascular tissue morphology traits have been observed. The protein localizes to the nucleus, cytosol, and cytoplasm. Studies of related genes in other species link this gene family to ABA sensitivity, osmotic stress tolerance, and salinity tolerance.
