CBF6 — Oryza sativa Japonica

Summary

OsCBF6 (Os09G0522200) on rice chromosome 9 encodes a DNA-binding transcription factor with an AP2/ERF domain. In rice, the gene is associated with responses to cold, drought, salt and other abiotic stresses, and has been linked to cold tolerance and stress tolerance. It is also associated with biological processes including cold acclimation, response to freezing, regulation of gene expression, and metabolism of sucrose, sulfur, polyamines, carotenoids and nucleotides. The encoded protein localises to the nucleus. Associations with seedling height, proline content, chlorophyll content and heat tolerance have been noted. Studies of related genes in other species link the family to drought, freezing and salt tolerance, while sequence similarity in other cereals connects the family to grain yield, winter survival, spikelet fertility and germination traits.
