Text-fig. 2. Light micrographs of Pinus spp. cuticles prepared with the modified, gentle bleaching procedure. a: Cuticle 1, Pinus sp. 1. Nearly the entire width of the leaf has been preserved. Five parallel rows of stomata are visible. b: Cuticle 1, close-up of (a). Two guard cells are visible around each stoma. c: Cuticle 1, close-up of eight stomata. Two guard cells and eight subsidiary cells are visible around each stoma. d: Cuticle 2, Pinus sp. 2. Some folding of the cuticle occurred during preparation, but many parallel rows of stomata on both sides of a thin, central midvein are evident. e: Cuticle 2, close-up of (d). Pairs of guard cells surround each stoma. f: Cuticle 2, close-up of (e). Subsidiary and epithelial cells can be observed around the stomata. in A Modified, Step-By-Step Procedure For The Gentle Bleaching Of Delicate Fossil Leaf Cuticles

Data from: Preparation of isolated guard cells, containing cell walls, from Vicia faba
<p>Stomatal movement, initiated by specialized epidermal cells known as guard cells (GCs), plays a pivotal role in plant gas exchange and water use efficiency. Despite protocols existing for isolating GCs through proplasting for carrying out biochemical, physiological, and molecular studies, protocols for isolating GCs with their cell walls still intact have been lacking in the literature. In this paper, we introduce a method for the isolation of complete GCs from <em>Vicia faba </em>and show their membrane to remain impermeable through propidium iodide staining. This methodology enables further in-depth analyses into the cell wall composition of GCs, facilitating our understanding of structure-function relationship governing reversible actuation within cells.</p>

Arabidopsis guard cell vacuoles imaged after the induction of vacuole fusion
<p>Wild type Arabidopsis thaliana plants from the Columbia-0 ecotype were grown in soil at 22C with a 16 h photoperiod. Leaves from 4-week old plants were cut in the morning and immediately processed to generate epidermal peels. Briefly, a small leaf fragment was applied abaxially to a coverslip coated with medical adhesive and all but the bottommost layers of abaxial cells containing the stomata were scrapped away with a razor. 1 mm thick silicone isolators (GraceBio #664170) were used to create wells around the adhesive for incubations. Epidermal peels were immediately incubated in stomata buffer (MES pH 6.1). To induce stomatal closure, peels were incubated in closing buffer (10 mM MES pH 6.1, 40 mM malate, 5 mM CaCl2, 10 µM BCECF, 50 mM ABA (Sigma Aldrich A1049) at 22C in the dark for two hours. To induce stomatal opening or vacuole fusion, ABA-treated peels were incubated in opening buffer (10 mM MES pH 6.1, 50 mM KCl) supplemented with 10 µM BCECF (Fisher Scientific B1170) and either 3 µM fusicoccin (Sigma F0537) or 33 µM wortmannin (Sigma W3144). Wortmannin-treated peels were kept in the dark, while fusicoccin-treated peels were exposed to the light for up to 1 h. All concentrated stocks were first dissolved in DMSO. Images of leaf epidermal peels were acquired after ABA incubation and after 20, 40 and 60 min of fusicoccin or wortmannin treatments. <br><br>Confocal laser scanning microscopy was carried out in a Zeiss LSM 980 confocal microscope. Images were taken with a 40× FCS water objective (1.1 N.A.). Acquisition of BCECF fluorescence was accomplished with 405 nm laser excitation and 495-550 nm emission filter set. Images were acquired with an Airyscan detector with a pinhole size of 2.5 airy units.</p>
