CBF1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0628110, designated HvCBF1, encodes a DNA-binding transcription factor containing an AP2/ERF domain. On barley chromosome 6H, this nuclear protein is associated with cold acclimation, vernalization response, response to cold, response to salt, salinity response, signal transduction, embryogenesis, and DNA-dependent transcription. It is linked to winter survival, cold tolerance, drought tolerance, salinity tolerance, and root dry weight. Studies of related genes in other species connect the family to grain yield, spikelet fertility, relative yield, chlorophyll content, and germination rate.
