Differences in the metabolite profiles of spinach (Spinacia oleracea L.) leaf in different concentrations of nitrate in the culture solution.
The nitrogen (N) status of a plant determines the composition of its major components (amino acids, proteins, carbohydrates and organic acids) and, directly or indirectly, affects the quality of agricultural products in terms of their calorific value and taste. Although these effects are guided by changes in metabolic pathways, no overall metabolic analysis has previously been conducted to demo...
متن کاملthe effects of different selenium concentrations on some morpho-physiological characteristics of spinach (spinacia oleracea l.)
selenium is a metalloid that it is antioxidant characteristics is proved for humans, animals and plants. however, some plants are known as hyper accumulators for selenium and sometimes seems to be useful for growth of some plants. in this paper, we have studied the effect of different selenium concentrations on growth and morpho-physiological characteristics of spinach. seeds of spinach were ge...
متن کاملNovel defensin subfamily from spinach (Spinacia oleracea).
Antimicrobial peptides (So-D1-7) were isolated from a crude cell wall preparation from spinach leaves (Spinacia oleracea cv. Matador) and, judged from their amino acid sequences, six of them (So-D2-7) represented a novel structural subfamily of plant defensins (group IV). Group-IV defensins were also functionally distinct from those of groups I-III. They were active at concentrations < 20 micro...
متن کاملCircular Dna Molecules Associated with Chloroplasts of Spinach, Spinacia Oleracea
Results of cytochemical studies (Sagan and Scher, 1961 ; Ris and Plaut, 1962 ; Kislev et al ., 1965) and of studies involving cell fractionation and buoyant density analyses (Sager and Ishida, 1963 ; Ray and Hanawalt, 1964 ; Brawerman and Eisenstadt, 1964 ; Edelman et al ., 1964 ; Wells and Birnstiel, 1969) have shown that chloroplasts of microorganisms and of higher plants contain DNA which is...
متن کاملThe effects of high concentrations of salts on photosynthetic electron transport in spinach (Spinacia oleracea) chloroplasts.
1. Photosynthetic electron transport from water to lipophilic Photosystem II acceptors was stimulated 3--5-fold by high concentrations (greater than or equal to 1 M) of salts containing anions such as citrate, succinate and phosphate that are high in the Hofmeister series. 2. In trypsin-treated chloroplasts, K3Fe(CN)6 reduction insensitive to 3-(3,4-dichlorophenyl)-1,1-dimethylurea was strongly...
