CBF1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0497660, also known as CBF1, CBF3, or DREB1H, encodes a DNA-binding transcription factor containing an AP2/ERF domain on barley chromosome 5H. This gene is associated with cold acclimation, vernalization response, response to cold and salt stress, signal transduction, and embryogenesis. The encoded protein localizes to the nucleus. Associations link this gene to winter survival, cold and drought tolerance, salinity tolerance, and root dry weight. Studies of related genes in other species connect the family to seasonality, grain yield, spikelet fertility, relative yield, chlorophyll content, quantum yield, germination rate, and root length.
