Pressbox (Press Release) - 6?��?1.2?(SE)?��m, n?=?38 and 48.0?��?1.0?��m, n?=?46], and contained less chloroplasts than the Capmatinib mesophyll cells (on average, respectively, 20.5?��?0.9, n?=?33, and 48.5?��?1.7, n?=?33). The mean Pf of the BSCs was significantly lower than that of the mesophyll cells (5.5?��?0.4?��m?sec?1, n?=?126 and 9.3?��?1.8?��m?sec?1, n?=?80, respectively; Figure?3a). The frequency distribution of the Pf values (which we examined because of the much smaller standard deviation in BSCs than in mesophyll cells, 4.4 and 15.9?��m?sec?1, respectively; Figure?3c,d) was much more symmetrical in the BSCs than in the mesophyll cells. We therefore sorted the mesophyll cells (crudely) into two groups: low?Pf (<25?��m?sec?1), comprising ?90% of the population; and high?Pf (��25?��m?sec?1), comprising ?10% of the population. Whereas the mean Pf of the high-Pf group of mesophyll cells was 58?��m?sec?1, that of the low-Pf group was 5.4?��?0.6?��m?sec?1 (n?=?74), equal to the Pf of the BSCs (Figure?3b). To study the effect of abiotic stress signals on the Pf of BS and mesophyll cells, we exposed the plants to ��drought�� for 8�C10?days (Experimental procedures). This treatment resulted in a 28% reduction in BSC Pf (Figure?4a), but had no effect on mesophyll cell Pf (Figure?S3; Table?1). Selleckchem PD-166866 An even stronger response (42% reduction in Pf) was seen in BSC protoplasts isolated from untreated control plants and incubated for 1�C4?h with 1?��m ABA (Figure?4b). As before, mesophyll cells remained unaffected by this treatment (Figure?S3; Table?1). A few minutes of treatment with 1?��m ABA did not affect Pf in either cell type (Table?1). Can a BSC Pf of ?5?��m?sec?1 support the transport of water though the whole plant? According to our estimate (Appendix?S1), BSCs Selleck Givinostat with this Pf can support the transpiration of 4.6?ml?g?1 leaf (fresh weight) per day. The measured transpiration of the whole Arabidopsis plant was ?2?g water?g?1 (fresh weight) per day (see Experimental procedures), hence the BSCs �C in their conducting mode �C would not constitute a limiting factor to water flow through the leaf. The distinct Pf changes in the BSCs in response to stress signals led us to address the involvement of their AQPs in these responses. Treatment with the AQP inhibitor HgCl2 (50?��m) nearly halved the rate of BSC swelling (Figure?S4), and reduced Pf by threefold (Figure?4c). The reduction in Pf was specific to AQPs, rather than a general effect of HgCl2 toxicity, as we used only a short, up to 10-min treatment, and the effect was reversed by a 10-min wash with 2?mm DTT (Figures?4c and S4). The leftward shift of the Pf distribution histograms of the HgCl2-treated BS protoplasts (Figure?S5) indicates a homogeneous effect on the whole BSC population. Blockage by HgCl2, and even more so its reversal, strongly indicated that it is the regulation of AQPs in BSCs that underlies the changes in their Pf values.
