Fig 7. Unigene37641 overexpression enhanced cold tolerance in transgenic A. thaliana.
(A) Expression level of Unigene37641 in T2 Arabidopsis transgenic lines (W-4 and W-6) and wild type (WT) plants using RT-PCR. (B) The WT and T2 plants were cultured on MS medium for 1 week were shown in top row. Seedlings were grown at 4°C (6 h per day) for 2 weeks were shown in bottom row. (C) Comparison of seedling fresh weight after cold treatment. The mean value of fresh weights and the standard errors were calculated based on three replicates.
