Proline accumulation and expression of proline metabolism genes in wild-type (WT) Arabidopsis: (A) effect of ANE and LPC on the accumulation of proline in the leaves of wild type Arabidopsis (Col-0) in response to freezing stress (Data are the means ± SE) and (B) Real time-PCR analysis of expression of genes encoding Δ1-pyrroline-5-carboxylate synthetase (P5CS) and prolinedehydogenase (ProDH). Bar with * is significantly different (P ≤ 0.05) from that of the control treatment.
