Differentially expressed genes (DEGs) in stress-sensitive (Pusa-44) and stress-tolerant (NIL-23) rice genotypes grown hydroponically under P-starvation stress. A Differentially and commonly up-regulated genes in shoot of the contrasting rice genotypes, B differentially and commonly up-regulated genes in root of the contrasting rice genotypes, C differentially and commonly down-regulated genes in shoot of the contrasting rice genotypes, D differentially and commonly down-regulated genes in root of the contrasting rice genotypes. Shoot and root tissues were collected from 45-day-old plants, continuously grown under control (16 ppm inorganic phosphorus) or treatment (0 ppm), and used for whole transcriptome analysis
