Moisture meter readings normalised (MMRnorm) to the tissue water content (DW basis) of the fresh fully hydrated leaves and the dried re-humidified leaves. WT, wild-type; WM, water-mutant; NE, non-expanded leaves; E, expanded leaves. Data are means ±standard error. Means with the different letters are significantly different (P < 0.05; Tukey’s tests)
