Transcript levels of CBF1, CBF3, and different cold-inducible genes in acex55 and acex506 mutants. RNA-blot hybridizations were performed with total RNA isolated from 4-week-old Col (WT) and mutant plants grown under control conditions (C) or exposed to 4 °C for the indicated times. Specific probes for CBF1 and CBF3, as well as for CBF target genes COR15A, COR47, KIN1, and LTI78, and the non-CBF-target gene RCI2A were used for hybridizations. The transcript levels of CBF2 in the mutants are shown as internal controls. Similar amounts of RNA were present in each sample as confirmed by ethidium bromide staining of rRNA.
