The acquisition of freezing tolerance is key to the survival of many plants in temperate regions. Investigations into the molecular basis for this tolerance, mostly in the model plant Arabidopsis, have discovered that the CBF pathway is important for this process: Activation of this pathway by low, non-freezing temperatures is sufficient to increase freezing tolerance. Plants contain more than one CBF gene but it is not known which is required to protect tissues that are essential for survival.

获得冷冻耐受性是温带地区许多植物生存的关键。对这种耐受性的分子基础的研究（主要是在模式植物拟南芥中）发现，CBF 途径对此过程很重要：通过低非冷冻温度激活该途径足以提高冷冻耐受性。植物含有多个 CBF 基因，但尚不清楚哪一种基因是保护生存所必需的组织所必需的。
