Gene-chip Venn diagrams and functional classification pie charts by function for genes impacted by ablation of OsNADK1 and drought treatment. a and b Differences in gene expression between osnadk1 and WT (cv. Dongjin) plants under normal growth and drought conditions. Number of upregulated (a) or downregulated (b) genes in osnadk1 under normal (purple) or drought (blue) conditions and under both experimental conditions (crossing of purple and blue), respectively. c and d The functional classification of genes that were differentially expressed in osnadk1 and WT under normal conditions (c) and drought conditions (d), respectively. The gene number and percentage for each functional category are shown. Only genes for which expression changed by two or more fold (p ≤ 0.05) were used to draw the Venn diagrams and pie charts. The values are averages of three independent replicates. Control: soil moisture, 47.3%; drought: soil moisture, 8.5%
