Illumination of 3 day old etiolated radish seedlings with continuous white light results in a progressive accumulation of chlorophyll a and b. Both pigments are bound in a different way to the thylakoid chlorophyll-proteins, which appear parallel to the formation of chlorophylls. By applying the SDS-PAGE method to SDS-digested chloroplasts, it was possible to show that the chloroplasts of radis...

In plants, the formation of isopentenyl diphosphate and dimethylallyl diphosphate, the central intermediates in the biosynthesis of isoprenoids, is compartmentalized: the mevalonate (MVA) pathway, which is localized to the cytosol, is responsible for the synthesis of sterols, certain sesquiterpenes, and the side chain of ubiquinone; in contrast, the recently discovered MVA-independent pathway, ...

The study of the pigment apparatus (chlorophylls, carotenoids) and flavonoids will allow to reveal plants adaptation mechanisms, which subsequently can be used in ecological biochemical studies. purpose is determine content photosynthesis pigments phytomass hydroponically grown garden sage (Salvia officinalis L.) compared with open soil. Two varieties were studied: ‘Dobrinya’ ‘Kubanets’ from tw...

The most widely distributed dinoflagellate plastid contains chlorophyll c(2) and peridinin as the major carotenoid. A second plastid type, found in taxa such as Karlodinium micrum and Karenia spp., contains chlorophylls c(1) + c(2) and 19'-hexanoyloxy-fucoxanthin and/or 19'-butanoyloxy-fucoxanthin but lacks peridinin. Because the presence of chlorophylls c(1) + c(2) and fucoxanthin is typical o...

Nitrogen is a major plant macronutrient and its supply affects the entire metabolism of plants. This study evaluated effect different nitrogen concentrations in nutrient solution: 0, 4.2, 8.4, 12.6 mg L?1 Mexican marigold (Tagetes erecta L.) var. Inca plants an open soilless culture system under greenhouse conditions on concentration chlorophylls, carotenoids, phenolics, flavonoids derived from...

The study monitored the effect of differentiated mineral nutrition microgreens species by solution sodium selenate (2 mg Se/L) on content Se, chlorophylls, and other minerals. Chlorophylls were measured spectrophotometrically, Se electrothermal atomic absorption method (ETAAS) with Zeeman-effect background elements’ concentration was performed a dual Inductively coupled plasma emission spectros...

plants are always exposed to vast aspects of either environmental biotic or abiotic stresses and those stresses affecting the plant growth and therefore crop production. molecular and physiological mechanisms influence plant resistance to environmental stresses, therefore the identification of these mechanisms can be an important step in challenging the damages. in this study, plant physiologic...
