Expression Profiling of Abiotic Stress-Inducible Genes in response to Multiple Stresses in Rice (Oryza sativa L.) Varieties with Contrasting Level of Stress Tolerance

Figure 4

Semiquantitative RT-PCR analysis showing differential gene expression in leaf tissues (a) and roots (b) of 12-day-old seedlings of IR-29 (salt sensitive), Pokkali, and Nonabokra (both salt tolerant) rice cultivars in response to cold (4°C); stress was imposed for 6/24 hours to detect the transcript level in leaves, whereas for roots, the durations of stress treatment were 24 hours (in IR-29 and Pokkali) and 6/24 hours (in Nonabokra); the expression of each gene was compared relative to its expression in control C (untreated) sample (0 h).
