Development of the Primary Photochemical Apparatus of Photosynthesis during Greening of Etiolated Bean Leaves.
Seven-day-old dark-grown bean leaves were greened under continuous light. The amount of chlorophyll, the ratio of chlorophyll a to chlorophyll b, the O(2) evolving capacity and the primary photochemical activities of Photosystem I and Photosystem II were measured on the leaves after various times of greening. The primary photochemical activities were measured as the photo-oxidation of P(700), t...
متن کاملCatabolism of [1-C]levulinic Acid by etiolated and greening barley leaves.
Levulinic acid (LA), a competitive inhibitor of delta-aminolevulinic acid (ALA) dehydratase (EC 4.2.1.24), has been used extensively in the study of ALA formation during greening. When [1-(14)C]LA is administered to etiolated barley (Hordeum vulgare L. var. Larker) shoots in darkness, (14)CO(2) is evolved. This process is accelerated when such tissues are incubated with 2 millimolar ALA or plac...
متن کاملThe effects of levulinic Acid and 4,6-dioxoheptanoic Acid on the metabolism of etiolated and greening barley leaves.
Application of levulinic acid (LA), a competitive inhibitor of delta-aminolevulinic acid (ALA) dehydratase, to greening plant tissues causes ALA to accumulate at the expense of chlorophyll. 4,6-Dioxoheptanoic acid (DA), which has been reported to be an effective inhibitor of this enzyme in animal systems, has a similar but more powerful effect on ALA and chlorophyll metabolism in greening leave...
متن کاملKinetin affects the level of chloroplast polyamines and transglutaminase activity during senescence of barley leaves.
We analysed the level of polyamines (PAs) bound to thylakoids and the level and activity of thylakoid transglutaminases throughout barley leaf senescence, retarded by kinetin. The level of PAs bound to thylakoids changed in senescing barley leaves: bound putrescine (PU) and spermidine (SD) increased throughout senescence, whereas bound spermine (SM) decreased. Kinetin diminished the increase in...
