Source	Description
UniProt	Transcriptional 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}.
