CBF1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0497640, designated HvCBF1 on barley chromosome 5H, encodes an AP2/ERF domain-containing transcription factor. It is annotated with DNA-binding transcription factor activity and localises to the nucleus. The gene is associated with cold acclimation, vernalisation response, response to cold and salt, signal transduction, and embryogenesis. Trait associations 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, chlorophyll content, germination rate, root length, and quantum yield.
