Phenotypic comparison of wild type and 35S:MtRAV transgenic Arabidopsis thaliana under cold treatment. (A) Expression analysis of cold-related marker genes in 35S:MtRAVs transgenic plants by qRT-PCR: RD29B, COR78, and COR414-TM1. (B) Wild-type and 35S:MtRAV3 transgenic Arabidopsis thaliana were grown on 1/2 MS medium containing 1% agar and grown at 22°C for an additional 18-day. The plates were transferred to a -15°C growth chamber and incubated for 2 h, and then returned to normal growth for 24 h at 22°C. (C) After 24 h normal growth after the -15°C cold treatment, we counted the rate of surviving seedlings. This rate was expressed as a percentage (%). Independent t-tests demonstrated that there was significant difference (P < 0.05).
