Heat maps of ClOMT genes in (A) different tissues and (B) in response to cold, drought, or osmotic stress. The RNA-seq data were obtained from the CuGenDB (http://cucurbitgenomics.org/). Color coding was done according to the scale given. Boxes filled with dots indicate no detection. In (A), watermelon tissues included fruit flesh (FF), fruit rind (FR) 10, 18, 26, and 34 days after pollination, seeds 49 days after pollination, phloem, vascular bundle, root, and leaf tissues. Transcript levels were calculated as log2-transformed Reads Per Kilobase of exon model per Million mapped reads (RPKM). In (B), the watermelon seedlings were exposed to 4 °C for 6 h, unwatered for eight days, or treated with PEG 6000 (20%) on roots for 6 h. Leaf tissues were harvested after cold and drought, while root samples were taken after PEG 6000 treatment. The values were calculated as log2-transformed RPKM ratios of Treatment/Control.
