Proline Content and Metabolism during Rehydration of Wilted Excised Leaves in the Dark.
Excised bean (Phaseolus vulgaris) leaves were used to measure changes in proline content and proline metabolism during rehydration in the dark after the leaves had been incubated in the dark 24 hours in a wilted condition.The increase in nonprotein proline which occurs in wilted leaves stopped immediately upon rehydration, and thereafter levels of proline declined. The rate of decline and the f...
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 کاملRole of carbohydrates in proline accumulation in wilted barley leaves.
The effect of wilting on proline synthesis, proline oxidation, and protein synthesis-all of which contribute to proline accumulation-was determined in nonstarved barley (Hordeum vulgare L.) leaves. Nonstarved leaves were from plants previously in the light for 24 hours and starved leaves were from plants previously in the dark for 48 hours. Wilted leaves from nonstarved plants accumulated proli...
متن کاملThe effect of carbohydrates and arginine on arginine metabolism by excised bean leaves in the dark.
The effect of carbohydrate on arginine utilization by excised bean (Phaseolus vulgaris L. var. Tendergreen) leaves in the dark was studied by adding arginine to leaves differing in carbohydrate levels, and measuring the arginine content of the leaves at intervals. In nonstarved leaves, the arginine content decreased steadily after vacuum infiltration of 10 mm arginine and was essentially comple...
