Fig. 4From: Identification of WRKY transcription factor family genes in Pinus massoniana Lamb. and their expression patterns and functions in response to drought stressHeatmap of PmWRKY expression using RNA-seq data. Blue represents low expression levels, and red represents high expression levels. C and D represent the control group (normal growth, C) and the treatment group (drought stress, D), respectively; 1, 2, and 3 represent the control and drought treatments on the 7th day, 7Â h after rewatering on the 8th day, and the 8th day, respectively. TBtools was used to generate the gene expression heatmapBack to article page
