ABI5 — Camelina sativa

Summary

CSA09G034290 (ABI5, also known as CsDPBF2 or CsBZIP67) on Camelina sativa chromosome 9 encodes a bZIP transcription factor with DNA-binding, protein homodimerization, and transcription coactivator activities, as well as protein phosphatase activity. This gene is associated with seed dormancy regulation, seed coat development, pollen maturation, and fatty acid and lipid metabolism. It is linked to the upregulation of abscisic acid (ABA) and gibberellic acid (GA) signaling pathways, as well as the downregulation of seed germination and both ABA and GA signaling. Associations include linoleic and linolenic acid content, seed size and set, nitrate sensitivity, osmotic and abiotic stress responses, stomatal closure, transpiration, leaf senescence, and plant size. Studies of related genes in other species connect the family to drought, salt, and freezing tolerance, ABA sensitivity, and flowering time.
