Figure 5 | KC1, its VSD, and SYP121ΔC suppress plant growth and, differentially, K+ and osmotic content. a, Vegetative rosettes of 4-week-old wild-type Arabidopsis and representative lines stably transformed to express secYFP and, on dexamethasone (Dex) induction, full-length KC1 K+ channel (KC1wt), its VSD (VSDwt), the up (closed, VSDF129W) and down (open, VSDD132E) conformers, and SYP121ΔC as a control. Plants were grown in the presence of 10 μM dexamethasone (Dex) and expression was verified by immunoblot (Fig. 4). Plants of the same lines grown in parallel −Dex were indistinguishable from the wild-type. b, Mean rosette surface areas for each set of three lines grown with 10 μM Dex normalized to mean areas for the lines grown −Dex.
