ABF4 — Camelina sativa

Summary

CsABF4 (CSA01G022300) on Camelina sativa chromosome 1 encodes a bZIP transcription factor of the BZIP46-like family with sequence-specific DNA-binding and protein kinase activity. The gene is associated with the upregulation of chlorophyll breakdown and abscisic acid-mediated signaling, as well as the regulation of leaf senescence, seed germination, stomatal movement, and pollen tube growth. It has been linked to responses to hydrogen peroxide, UV-B, far-red light, hypoxia, and ethylene signaling. CsABF4 is associated with seed yield, photosynthetic ability, transpiration rate, water stress response, photoperiod-sensitive flowering time, leaf elongation rate, root and tuber traits, and sensitivities to iron, magnesium, manganese, nitrate, aluminum, and jasmonic acid. Studies of related genes in other species associate the family with drought, salt, cold, and heat stress tolerance, as well as tuber yield and quality.
