BoCNGC expression profiles in different plant parts and in response to stress. a Normalized BoCNGC expression levels (fragments per kilobase of exon model per million mapped reads) in different Brassica oleracea plant parts.
b Effect of biotic stress on the expression levels of BoCNGC genes in the leaves of 25 days old seedlings inoculated with Xanthomonas campestris pv. campestris at 24 hpi. c Effect of abiotic stress on the expression levels of BoCNGC genes in the leaves of 25 days old seedlings subjected to cold stress at 4 °C for 24 h. The Y-axis indicates the relative expression levels of treated versus untreated control (CK). The error bars were calculated based on three biological replicates using standard deviation. The asterisks on bars represent the statistical significance of each gene at p ≤ 0.01 based on LSD test
