The Gene Cluster-To Frost Resistance and Beyond.

The pivotal role of / transcriptional factors in crops involved in the abiotic stress response has been highlighted. The CBFs represent an important hub in the ICE-CBF-COR pathway, which is one of the most relevant mechanisms capable of activating the adaptive response to cold and drought in wheat, barley, and rye. Understanding the intricate mechanisms and regulation of the cluster of genes harbored by the homoeologous chromosome group 5 entails significant potential for the genetic improvement of small grain cereals.
