Relative water content in rosette leaves (LRWC) (a), daily plant transpiration (b) and transpiration normalized to the rosette area (c) as a function of soil water potential (ψsoil) in WT, smr1, gai-1 and gai-1 smr1 plants. The dots denote individual plants (n ≥ 15) and the dashed lines represent the fitting functions of the data for each genotype. d, e Drought resistance of WT, smr1, gai-1 and gai-1 smr1. Four-weeks old plants were maintained at 15–20% LRWC for four days and survival rates were determined three days after rewatering. In (d), the dots represent independent assays (n = 10, 12, 15, 15 for WT; 10, 12, 13, 15 for smr1; 8, 12, 15, 15 for gai-1; 8, 16, 13, 15 for gai-1 smr1). The black horizontal lines represent the mean values. Letters indicate statistical groups obtained using Tukey’s post hoc test (p < 0.001) following one-way ANOVA. In (e), representative images after rewatering the plants are shown. In contrast to gai-1, the inflorescence of gai-1 smr1 plants had bolted and contained mature flowers and fruits by the end of the assay (see also Supplementary Fig. 6c). Scale bar, 10 cm. Source data are provided as a Source Data file.
