Effect of TaVRN-B2 over-expression on the accumulation of cold-regulated transcripts.

A) Transcript level of CBFs genes. Control (35S::GUS) and transgenic 35S::TaVRN-B2 plants (line 1) grown under long day conditions and exposed to 4°C for 3 and 6 hours. B) Transcript level of CORs genes. Control (35S::GUS) and transgenic 35S::TaVRN-B2 plants (line 1) grown under long day conditions at 4°C for 1 and 2 weeks. Transcripts levels were measured by RT-PCR. Each experiment was repeated three times using RNA prepared from three biological samples with similar results.
