Chlorophyll Photobleaching in Pigment-Protein Complexes
Pigment photobleaching was performed in thylakoid membranes of Hordeum vulgare (wild type, mutant Chlorina f2, Norfluranzon treated seedlings) and in pigment-protein complexes (CP-I and LHCP) isolated from H. vulgare and Chlamydomonas reinhardtii. Multiphasic kinetics were obtained in all of the above cases. Energy transfer towards pigments absorbing at longer wavelength is postulated as a gene...
متن کاملHigh-temperature thermoluminescence of chlorophyll as a method to study lipid peroxidation in planktonic algae
Chlorophyll-containing cells of algae, photosynthetic bacteria, and plants often exhibit strong red luminescence when heated to temperatures above 70 °C. This high-temperature thermoluminescence (HTL) originates mostly from thermally induced degradation of lipid cycloperoxides present in thylakoid membranes. The degrading cycloperoxides can transiently form carbonyl species in excited triplet s...
متن کاملpH control of the chlorophyll a fluorescence in algae.
The pH of the suspension medium was found to have a remarkable influence on the "slow" (min) time course of Chlorophyll a fluorescence yield in the green alga Chlorella pyrenoidosa and in the blue-green alga Anacys t i s nidulans. In Chlorella, the decay of fluorescence yield, in the Ito 5-rain region, is strongly retarded at alkaline pH ; this decay rate shows an optimum at pH 67. In Anacystis...
متن کاملChlorophyll b can serve as the major pigment in functional photosystem II complexes of cyanobacteria.
An Arabidopsis thaliana chlorophyll(ide) a oxygenase gene (cao), which is responsible for chlorophyll b synthesis from chlorophyll a, was introduced and expressed in a photosystem I-less strain of the cyanobacterium Synechocystis sp. PCC 6803. In this strain, most chlorophyll is associated with the photosystem II complex. In line with observations by Satoh et al. [Satoh, S., Ikeuchi, M., Mimuro...
متن کاملChlorophyll-Protein Complexes from Euglena gracilis and Mutants Deficient in Chlorophyll b: I. Pigment Composition.
The use of n-octyl-beta-d-glucopyranoside along with sodium dodecyl sulfate improves the retention of chlorophyll (Chl) by chlorophyll-protein complexes (CPs) prepared from thylakoids of Euglena gracilis Klebs var bacillaris Cori and yields several additional complexes. Thylakoids from wild-type (WT) cells, solubilized in these detergents and subjected to polyacrylamide gel electrophoresis at 0...
