Fig. 4From: Transcriptome profiling of Malus sieversii under freezing stress after being cold-acclimatedHeat map of the relative expression levels of DEGs involved in sugar metabolism and the antioxidant defense system; (A) Sugar and starch metabolism-related genes; (B) Antioxidant-related genes. The red and blue colors indicate high and low expression levels (log2 fragments per kilobase of transcript per million mapped reads, FPKM), respectivelyBack to article page
