The phenotypes of the atpr5k2-1 mutant and AtPR5K2-overexpressing (AtPR5K2-OX) plants in response to drought stress. (A) Wild type (WT), atpr5k2-1, and AtPR5K2-overexpressing plants (AtPR5K2-OX #1 and #2) were grown in soil with sufficient water for 3 weeks (upper row). Water was then withheld from the plants for 11 days (middle), after which the plants were rewatered for 1 day (bottom). The survival rates of the WT, atpr5k2-1, and AtPR5K2-OX #1 and #2 lines under drought conditions were assessed in four replicates (n = 48). (B) Transpirational water loss was measured in detached leaves of 4-week-old WT, atpr5k2-1, and AtPR5K2-OX #1 and #2 plants. The fresh weights were measured at the indicated time points, and water loss was normalized relative to a percentage of their initial fresh weight. Error bars indicate the standard deviation from three independent experiments. Asterisks represent significant differences from the WT (*0.01 < p ≤ 0.01, Student’s t test).
