We have recognized two genes from Arabidopsis that present excessive similarity with CBF1, a gene encoding an AP2 domain-containing transcriptional activator that binds to the low-temperature-responsive factor CCGAC and induces the expression of some cold-regulated genes, rising plant freezing tolerance. These two genes, which we’ve got named CBF2 and CBF3, additionally encode proteins containing AP2 … Read more
