Transcription factor CBF and its cold tolerance mechanism

This paper summarized the discovery, classification, molecular mechanism in the process of coldtolerance and some associated molecular information regulating CBF and regulated by CBF, as well as the latest progress of CBF research. Low temperature is one of the most important environmental factors influencing plant growth and production performance. With the development of molecular biology, the molecular mechanism that plants survive in stress environmental conditions has become a hot field in the study of botany nowadays. Transcription factor is the accessory factor that RNA polymerase needs in transcription initiation. Eukaryotic RNA polymerase can not start its transcription unless the transcription factor (protein) is binding at its recognition sequence on DNA. Transcription factor CBF is an important regulator that exists extensively in the process of cold acclimation of all plants and it recognizes CRT／DRE（Crepeat/dehydrationresponsive element）in COR and starts its transcription.
