ABI5 — Camelina sativa

Summary

CSA04G024180 (symbol ABI5, also known as CsDPBF2 or CsBZIP67) encodes a bZIP transcription factor on Camelina sativa chromosome 4. The product possesses DNA-binding, transcription coactivator, protein phosphatase, and kinase-binding activities. This gene is associated with seed coat development, seed dormancy regulation, gibberellic acid and abscisic acid signaling, fatty acid and lipid metabolism, lignin anabolism, nitrogen utilization, pollen maturation, phloem transport, and hyperosmotic salinity response. It localizes to the nucleus, cytoplasm, cytosol, and mitochondria. Associations with agronomic traits include seed size, seed set percent, linoleic and linolenic acid content, nitrate sensitivity, shoot elongation, whole plant size, transpiration rate, stomatal opening and closure, leaf size and senescence, anthocyanin content, osmotic and oxidative stress responses, low temperature stress response, and male sterility. Related genes in other species are linked to salt and cadmium stress tolerance, chlorophyll degradation, plant height, dwarfism, and male fertility.
