ABF4 — Camelina sativa

Summary

CsABF4 (CSA15G027010) on Camelina sativa chromosome 15 encodes a bZIP transcription factor with sequence-specific DNA-binding and protein kinase activities. The gene is associated with regulation of abscisic acid-mediated signaling, chlorophyll breakdown, leaf senescence, pollen tube growth, seed germination, stomatal movement, and responses to UV-B, hydrogen peroxide, hypoxia, and far-red light. It has been linked to traits including seed yield, photosynthetic ability, transpiration rate, leaf elongation, shoot branching, root length, flower development, and sensitivities to iron, magnesium, manganese, nitrate, aluminum, and jasmonic acid. Studies of related genes in other species connect the family to drought tolerance, salt tolerance, cold tolerance, dehydration response, and tuberization.
