Developmental phase-dependent transcriptome reprogramming under drought of representative DVG clusters. A. Expression dynamics under the 3 different water conditions and across the 3 days of 3 representative clusters (C01-C03) including 3324 DVGs. Red indicates up-regulation, blue indicated down-regulation and white indicates no change. B. The fold change of all genes (grey) in the corresponding clusters under WW and SD on Day 7 from 2 developmental phase comparisons. The light red line represents the average fold change from E/M of all genes in each cluster; the dark red line represents the average fold change from E/L of all genes in each cluster. The mini graph within each box represents the general trend of gene expression throughout the 3 developmental phases. C. GO enrichment based on genes from the corresponding clusters. Colors of the dots refer to different general biological processes, and sizes of the dots refer to the level of enrichment (-log₁₀FDR). D. The expression level (average RPKM values between the 3 days under WW or SD across the 3 developmental phases) of representative genes from the corresponding clusters. (a): genes from C01; (b): genes from C02; (c): genes from C03. Square indicates that the gene has a previously reported function in development, triangle indicates that the gene has a previously reported function in drought response, and circle indicates that the gene has no published functional study. Each color represents a different gene, though the same color in different graphs does not refer to the same gene. Solid line represents WW, dashed line represents SD
