Metabolism of Abscisic Acid in Guard Cells of Vicia faba L. and Commelina communis L.
Metabolism of abscisic acid (ABA) was investigated in isolated guard cells and in mesophyll tissue of Vicia faba L. and Commelina communis L. After incubation in buffer containing [G-(3)H]+/-ABA, the tissue was extracted by grinding and the metabolites separated by thin layer chromatography. Guard cells of Commelina metabolized ABA to phaseic acid (PA), dihydrophaseic acid (DPA), and alkali lab...
متن کاملRelationship between Respiration and Photosynthesis in Guard Cell and Mesophyll Cell Protoplasts of Commelina communis L.
A mass spectrometric method combining (16)O/(18)O and (12)C/(13)C isotopes was used to quantify the unidirectional fluxes of O(2) and CO(2) during a dark to light transition for guard cell protoplasts and mesophyll cell protoplasts of Commelina communis L. In darkness, O(2) uptake and CO(2) evolution were similar on a protein basis. Under light, guard cell protoplasts evolved O(2) (61 micromole...
متن کاملFirst Report of Stem Rot on Asiatic Dayflower (Commelina communis L.) Caused by Sclerotium rolfsii in Korea
Stem rot was found for the first time on the Asiatic dayflower plant (Commelina communis L.) in Korea. A detailed description of this Korean specimen is given, along with its rDNA internal transcribed spacer sequence. The fungus was identified as Sclerotium rolfsii Saccardo based on mycological characteristics and molecular data.
متن کاملAccumulation and Conversion of 3-O-M ethyl-D-Glucose in Guard Cells o f Commelina communis L
Guard Cells, Stomata, Commelina, Carbohydrate Accu mulation Young plants of Commelina communis L. were allowed to take up [U-14C]-3-0-methyl-D-glucose through the cut stem via the transpiration stream. The distribution of this tracer carbohydrate in the plant was analyzed and its ac cumulation investigated in the epidermal tissue by micro autoradiography. Over feeding periods from 1 to 24 h ...
متن کاملRapid low temperature-induced stomatal closure occurs in cold-tolerant Commelina communis leaves but not in cold-sensitive tobacco leaves, via a mechanism that involves apoplastic calcium but not abscisic acid.
Commelina communis stomata closed within 1 h of transferring intact plants from 27 degrees C to 7 degrees C, whereas tobacco (Nicotiana rustica) stomata did not until the leaves wilted. Abscisic acid (ABA) did not mediate cold-induced C. communis stomatal closure: At low temperatures, bulk leaf ABA did not increase; ABA did not preferentially accumulate in the epidermis; its flux into detached ...
