摘要 Low temperature is one of the most important environmental stresses that affect plant survival,growth and development.In response to cold stress,hundreds of genes are upor down-regulated in plants[1].The C-repeat binding factor(CBF)regulon is the best-understood cold-responsive transcriptional module[1].In Arabidopsis,there are three CBF genes,i.e.,CBF1,CBF2 and CBF3.They are rapidly in- Low temperature is one of the most important environmental stresses that affect plant survival,growth and development.In response to cold stress,hundreds of genes are upor down-regulated in plants[1].The C-repeat binding factor(CBF)regulon is the best-understood cold-responsive transcriptional module[1].In Arabidopsis,there are three CBF genes,i.e.,CBF1,CBF2 and CBF3.They are rapidly.
