Figure 4.

Expression profiles of OsPPs under abiotic stress conditions. Three experimental stress conditions are denoted as CS: Cold Stress, DS: Drought Stress, SS: Salt Stress and S: control, 7 days old unstressed seedling. Color bar at the base represents log2 expression values, thereby green color representing low level expression, black shows medium level expression and red signifies high level expression. A gene is considered differentially expressed under abiotic stress conditions if it is up- or down-regulated at least two-fold, at P-value ≤ 0.05, with respect to the 7-days-old unstressed seedling.
