Diagram of cold-responsive transcriptional network in plant. Solid arrows indicate activation, whereas lines ending with a bar show negative regulation. Abbreviations: CBF, C-repeat binding factor (an AP2-type transcription factor); ICE1, inducer of CBF expression 1 (a MYC-type bHLH transcription factor); LOS2, low expression of osmotically responsive genes 2 (a bifunctional enolase with transcriptional repression activity); ZAT12, a zinc finger protein involved in high light and cold acclimation; ZAT10, related to Cys2/His2-type zinc-finger proteins found in higher plants; KIN1, encodes protein kinase APK2a; ERD10, encodes a gene induced by low temperature and dehydration
