The uptake of glucose and other carbohydrates into the guard cells of Commelina communis L. was found to inhibit the opening of the stomata. The concentration of glucose necessary to achieve about 50% inhibition was of the same order of magnitude as the potassium concentration required for opening;
The localization of enzymes involved in the flow of carbon into and out of starch was determined in guard cells of Commelina communis. The guard cell chloroplasts were separated from the rest of the cellular components by a modification of published microfuge methods. The enzymes of interest were

Tradescantia pallida (Wandering jew)-a succulent perennial herb-was screened to be a potent chromium (Cr) accumulator. Its ability to grow under Cr stress was examined by studying biochemical changes and physiological response of the plant in presence of 5-20 mg L(-1) Cr(VI) concentration in

Contact with members of the plant family Commelinaceae, which includes wandering jew (Commelina spp. formerly called Tradescantia spp.) and inch plant (Callisia fragrans), can cause cell-mediated contact dermatitis in dogs. However, reports of canine IgE-mediated hypersensitivity to these plants
