Expression of the known (76_up_genes_root) Pi-starvation–inducible genes in the stress-sensitive (Pusa-44) and stress-tolerant (NIL-23) rice genotypes grown hydroponically under P-starvation stress. Shoot and root tissues were collected from 45-day-old plants, continuously grown under control (16 ppm inorganic phosphorus) or treatment (0 ppm Pi), and used for whole transcriptome analysis
