CBF1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0497620, designated CBF1 and also known as CBF12, HvCBF4, HvDREB1H and DREB1H, is located on barley chromosome 5H. It encodes a CBF12 protein containing an AP2/ERF domain, classifying it as a DNA-binding transcription factor. 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. Associations with agronomic traits include cold tolerance, salinity tolerance, drought tolerance, winter survival, and root dry weight. Studies of related genes in other species link the family to seasonality, grain yield, relative yield, spikelet fertility, germination rate, root length, chlorophyll content, and quantum yield.
