Abscisic Acid Metabolism in Water-stressed Bean Leaves.
Phaseic acid (PA) and dihydrophaseic acid (DPA) are the major metabolites observed when (S)-2-(14)C-abscisic acid (ABA) is fed to 14-day excised primary bean leaves (Phaseolus vulgaris L. cv. Red Kidney). The distribution of (14)C in leaves which were wilted after feeding ABA appears to be the same as that observed in unwilted leaves. A reduction in the relative specific radioactivities of the ...
متن کاملMetabolism of cytidine and uridine in bean leaves.
The metabolism of cytidine-2-(14)C and uridine-2-(14)C was studied in discs cut from leaflets of bean plants (Phaseolus vulgaris L.). Cytidine was degraded to carbon dioxide and incorporated into RNA at about the same rates as was uridine. Both nucleosides were converted into the same soluble nucleotides, principally uridine diphosphate glucose, suggesting that cytidine was rapidly deaminated t...
متن کاملMalonate as a Participant in Organic Acid Metabolism in Bush Bean Leaves.
Interest in malonic acid has been largely directed towards its role as a competitive inhibitor of succinic dehydrogenase. Very little attention has been directed toward the occurrence of malonic acid in plants or toward the metabolismi of malonic acid per se. Bentley ( 1 ) recently showed malonate to be present in some 18 species of legumes, one of which had concentrations as high as 2 mg/g dry...
متن کاملThe effect of wilting on proline metabolism in excised bean leaves in the dark.
The effects of wilting on the fate of proline and on the rates of nonprotein proline formation and utilization have been determined in excised bean leaves. Wilting did not alter the fate of exogenously added (14)C-l-proline (2 mm) in either non-starved leaves (from plants previously in the light) or starved leaves (from plants previously in the dark). The fate of proline in nonstarved leaves wa...
متن کاملRespiratory Carbon Metabolism following Illumination in Intact French Bean Leaves Using C/C Isotope Labeling
The origin of the carbon atoms in the CO2 respired by French bean (Phaseolus vulgaris) leaves in the dark has been studied using C/C isotopes as tracers. The stable isotope labeling was achieved through a technical device that uses an open gas-exchange system coupled online to an elemental analyzer and linked to an isotope ratio mass spectrometer. The isotopic analysis of the CO2 respired in th...
