Fig. 8From: Genome-wide identification and analysis of class III peroxidases in Betula pendulaResponses of BpPOD genes expression to cold treatment. Different time are exhibited below each column. The BpPOD genes were listed at the right of the expression array, and the colour box from blue (0) to orange (2.5) indicate an increased expression level is shown at the right of the figure. Color scale represent the normalized value of the expression. For the sake of unified comparison, the normalized value of the expression was log10 transformedBack to article page
