Blue light-induced, intrinsic vacuolar fluorescence in onion guard cells.

Guard cells of onion irradiated with broad-band blue light display a green intrinsic fluorescence. The fluorescence has been found in eleven species of Allium, but it has not been observed in any other monocot or dicot examined. The fluorescence occurs only in guard cells and is absent in neighbouring epidermal cells. During development it is first apparent in guard mother cells soon after the asymmetric division. Microscopic observation reveals that the fluorescence is associated with the…

On the properties of fluorescing compounds in guard and epidermal cells of Allium cepa L.

Onion guard cells, in contrast to those of Vicia and Pisum, do not require an alkaline treatment in order to fluoresce, and this may reduce the sensitivity for the detection of flavins in guard cells.

Epicuticular Phenolics Over Guard Cells: Exploitation for in situ Stomatal Counting by Fluorescence Microscopy and Combined Image Analysis

Given that the alkali-induced blue fluorescence of the guard cells is a common characteristic of all plants examined, it could be used as a rapid and convenient method for in situ measurements of the number, distribution and size of stomatal complexes.

The Blue Light Response of Stomata and the Green Vacuolar Fluorescence of Guard Cells

Guard cells modulate gas exchange between the leaf and the environment by regulating the aperture of the stomatal pore. The changes in aperture are mediated by fluctuations in the turgor of the guard


Study on the 3-(3,4-dichlorophenyl)-1,1-dimethylurea-sensitive variable fluorescence kinetics of uncontaminated epidermal peels of C. comosum indicated that guard cell chloroplasts operate a normal, photosystem II-dependent, linear electron transport.

Changes in dye coupling of stomatal cells of Allium and Commelina demonstrated by microinjection of Lucifer yellow

Results are consistent with the reported absence of plasmodesmata in the walls of mature guard cells and the loss of symplastic transport may result from changes in these structures well in advance of their actual disappearance from the guard cell wall.

The vacuole system in stomatal cells ofAllium. vacuole movements and changes in morphology in differentiating cells as revealed by epifluorescence, video and electron microscopy

The development of autofluorescent vacuoles in the stomatal cells of Allium cepa and A. vineale was investigated using fluorescence microscopy of live cells, low light level television, cytochemistry and electron microscopy to discuss the significance of changes in the vacuole ontogeny and function and the mechanisms that control motility in plant cells.

Lucifer Yellow Uptake in Cells and Protoplasts of Daucas carota Visualized by Laser Scanning Microscopy

Control experiments support the contention that lucifer yellow uptake, as in other eukaryotic systems, occurs via endocytosis.

Three-dimensional distribution of the UV-inducible blue-green fluorescence in leaves

It is shown that blue-green fluorescence (BGF) mainly originates in the epidermal surface of Sorghum vulgare leaves and was also detected from the cell walls and stomata guard cells.



Light and Stomatal Function: Blue Light Stimulates Swelling of Guard Cell Protoplasts

It is postulated that a membrane-bound blue photoreceptor mediates a direct response of guard cells to light that swell when illuminated with blue light.

Action Spectra for Guard Cell Rb Uptake and Stomatal Opening in Vivia faba.

In the abaxial surface of leaf discs under air of normal CO(2) concentration, stomatal opening in white light approached its maximum at an intensity similar to that for epidermal strips, and at both quantum flux densities, the action spectra for opening in leaf discs were very similar to those for epidersmal strips.

The mechanism of stomatal movement in Allium cepa L.

It is shown in this paper, by histochemical and microprobe analyses, that in Allium — as in other plant species—the K+ concentration of the guard cells increases during stomatal opening, and the charges of the K+ ions in theGuard cells seem to be fully compensated by imported Cl- ions.

Light-sensitive membrane potentials in onion guard cells

It is argued that a proton-motive force could drive K+ uptake into the guard cells and the basic prediction of a light-sensitive, inside negative, MPD is generated, through intracellular recordings in guard cells of Allium cepa.

The Comparative Effects of Blue and Red Light on the Stomata of Allium cepa L. and Xanthium pennsylvanicum

It is concluded that blue light may promote stomatal opening by its effect on enzymes controlling the starch and soluble polysaccharide content of guard cells.

Production of guard cell protoplasts from onion and tobacco.

The assay showed that driselase has a 5-fold higher cellulytic activity than cellulysin and Driselase is, however, harmful to the GCP.

Electrophysiological properties of onion guard cells

Intracellular electrical recordings in onion (Allium cepa L.) guard cells show that they maintain a membrane potential difference (MPD), inside negative, and evidence indicates that the guard cells have two electrically distinct compartments, presumably delimited by the plasmalemma and tonoplast.


Flavins have been hypothesized to be components of the photoreceptor system, but they have been reported previously only in the paraflagellar bodies of intact cells and studies now suggest the presence of flavins also in Euglena eyespots.

Rapid, Blue‐Light‐Induced Transpiration Response Restricted to Plants with Grass‐like Stomata

It is shown that the response of transpiration to light is different in species from Gramineae and Cyperaceae compared to species from other families, and hypothesized that the rapid response to blue light is due to the special anatomy and/or function of the so-called grass-like (graminaceous) stomata of plants belonging to gramineae or Cyper Families.

Rapid, Blue‐Light Induced Transpiration in Avena

The transpiration responses of primary Avena leaves to blue-light pulses were investigated. Only light with wave length shorter than 524 nm can produce the rapid transpiration response. The action
