Fig. 9From: Genome-wide identification and analysis of class III peroxidases in Betula pendulaqRT-PCR analysis of POD genes in B. pendula under cold stress. The X-axis represents the time course of stress treatment and the Y-axis represents the relative expression level. Seedlings were sampled at 0, 1.5 and 3 after cold treatment. Data represent means ± SD in three replicatesBack to article page
