Source Description
UniProtTranscription activator that regulates freezing tolerance by affecting expression of CBF genes. {ECO:0000269|PubMed:24415840}.
UniProtTranscriptional activator involved in cold stress response (PubMed:14675437, PubMed:20807373, PubMed:22246661). Regulates positively the expression of genes involved in reactive oxygen species (ROS) scavenging such as peroxidase and superoxide dismutase during cold stress. Transactivates a complex gene network that have major effects on stress tolerance and panicle development (PubMed:20807373). {ECO:0000269|PubMed:14675437, ECO:0000269|PubMed:20807373, ECO:0000269|PubMed:22246661}.
UniProtTranscription factor involved in cold-regulation of CBF genes and in the development of freezing tolerance. May be part of a complex network of transcription factors controlling the expression of CBF genes and other genes in response to cold stress. Binds to the MYB recognition sequences in the promoters of CBF1, CBF2 and CBF3 genes (PubMed:17015446). Involved in drought and salt tolerance. May enhance expression levels of genes involved in abscisic acid (ABA) biosynthesis and signaling, as well as those encoding stress-protective proteins (PubMed:19161942). {ECO:0000269|PubMed:17015446, ECO:0000269|PubMed:19161942}.
