Effect of PIP1b Overexpression on Plant Water Consumption.

Water consumption by 30-day-old plants grown hydroponically was analyzed using a microelectronic potometer (R. Aharon, G. Galili, A. Blum, and Y. Kapulnik, unpublished data). The rate of water consumption was measured from the linear water absorption curve and was normalized to units of leaf area. Bars represent the standard errors of the means of at least five plants per genotype. Different letters above the columns indicate statistically significant differences at the 0.05 level. WT, wild type.
