这表明，低温能够诱导钙离子向细胞质内流入并发挥其信使功能，从而使抗冷基因得到表达而使南极冰藻具有抗冷的性质。
This suggest that Ca ions play an important role as the second messenger to induce the express of cold resistance genes to adapt the low temperature.
结果表明克隆到的目的片段具有启动子功能，并且在干旱、高盐、低温诱导胁迫下更能强烈地驱动下游基因的表达。
Result shows that cloning purpose fragment has the function of promoter, and it can regulate lower reaches gene expression intensely in drought, high-salt and cold.
CBF基因受到低温、干旱及高盐等非生物胁迫因子诱导表达，除了CBF 4外，其余的CBF基因都不依赖aba。
CBF genes are expressed when induced by abiotic stress factors such as low temperature, drought and high salty, etc. Except for CBF4, other CBF genes are independent on ABA.
