CBF1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0497610, designated HvCBF1 on barley chromosome 5H, encodes a DNA-binding transcription factor of the AP2/ERF domain family. The gene is associated with cold acclimation, vernalization response, response to cold and salt, signal transduction, embryogenesis, and DNA-dependent transcription, and its product localises to the nucleus. HvCBF1 has been linked 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, relative yield, spikelet fertility, germination rate, root length, chlorophyll content, and quantum yield.
