Incubation of greening barley leaves with cesium chloride (CsCl) results in photodynamic leaf lesions within 24 h due to an inactivation of uroporphyrinogen III decarboxylase, an enzyme of tetrapyrrole biosynthesis, and transient accumulation of uroporphyrin (ogen). To examine the mechanism of porphyrinogenesis, time kinetics of the accumulating(More)
The effects of overwatering (flooding) on the oxidative potential, the level of low-molecular-weight antioxidants, the content of stress proteins, and activities of antioxidant enzymes in green barley (Hordeum vulgare L.) seedlings were studied. Overwatering retarded barley seedling growth and induced hydrogen peroxide accumulation, a decrease in the total(More)
It is shown that Mg-protoporphyrin monomethyl ester as well as immediate chlorophyll precursors are localized in chloroplast submembrane particles, some of them being especially enriched. A conclusion is made that the centers of chlorophyll biosynthesis coupled with chloroplast submembrane particles perform a wide range of biosynthetic reactions beginning(More)
In dihaploid wheats, two evolutionarily unstable regions of the chloroplast genome were examined. These regions include the following genes, changes in which could be associated with albinism in anther culture: rbcL, encoding the large Rubisco subunit; psaA, encoding p700 apoprotein Ia; petA, encoding cytochrome f; atpB and atpE, encoding respectively beta(More)
