Inorganic nitrogen assimilation in Chlamydomonas.
Inorganic nitrogen is an essential nutrient for photosynthetic organisms. Its efficient use in nature involves adaptation of the organisms to the availability of the nitrogen supply, to changing environmental conditions, and to the provision of carbon and other nutrients. The unicellular alga Chlamydomonas provides a useful model to identify not only each of the components participating in the ...
متن کاملPhotosynthesis, Nitrogen Metabolism and Antioxidant Defense System in B-Deficient tea (Camellia sinensis (L.) O. Kuntze) Plants
Response of tea plants to B deficiency was studied in hydroponic medium under environmentally controlled conditions. Plants height, number of leaves and dry matter production of shoot and root were significantly decreased by B deficiency. Concentration of chlorophyll, carotenoids, anthocyanins and flavonoids was not affected by B deficiency in the young leaf, while a significant reduction of Ch...
متن کاملChanges in Antioxidative Responses to Low Temperature in Tea[Camellia sinensis (L) O. Kuntze] Cultivars
Effect of low temperature stress treatment in five selected clones of Camellia sinensis (T-17, TV-19, TV-25, TV-29, TV-30) was found to be significant. Guaiacol Peroxidase (GPX) decreased with decreasing temperature. PPO decreased with decreasing temperature showing highest activities at 20°C in all clones. CAT activit ies decreased in T-17, TV29, and TV-30 with decrease in temperature with exc...
متن کاملAssimilation of ammonium ions and reutilization of nitrogen in rice (Oryza sativa L.).
A major source of inorganic nitrogen for rice plants grown in paddy soil is ammonium ions. The ammonium ions are actively taken up by the roots via ammonium transporters and subsequently assimilated into the amide residue of glutamine (Gln) by the reaction of glutamine synthetase (GS) in the roots. The Gln is converted into glutamate (Glu), which is a central amino acid for the synthesis of a n...
متن کاملStudy on lead levels in infusion time of imported green and black tea (Camellia sinensis L)
Background: Nowadays, tea is the most popular and frequently consumed beverages in the world after water. There are some beneficial trace elements in tea such as fluoride, caffeine and essential minerals, although there may be heavy metals in tea leaves which threat seriously human health. Therefore, the main objective of current study was to determine and monitor lead content in imported black...
