CBF1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0497650, designated HvCBF1 on barley chromosome 5H, encodes a DNA-binding transcription factor containing an AP2/ERF domain. The gene is associated with cold acclimation, vernalization response, response to cold, response to salt, salinity response, embryogenesis, DNA-dependent transcription, and signal transduction, and its product localises to the nucleus. HvCBF1 is associated with winter survival, cold tolerance, drought tolerance, salinity tolerance, root dry weight, and SALTTL. Studies of related genes in other species link the family to grain yield, relative yield, spikelet fertility, seasonality, germination rate, root length, chlorophyll content, and quantum yield.
