Novel 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 کاملEffect of Cadmium Levels on Seed Germination and Seedling Growth of Spinach (Spinacia oleracea) Under Salinity Stress
Cadmium is highly toxic heavy metal. Soil factors such as pH, caution exchange capacity, CaCO3 content and salinity have a significant influence on Cd uptake by plants. Moreover, soil salinity has a great impact on crop yield in Iran. Therefore, the effect of four salt levels (0, 45, 90, 180 mM) of NaCl solutions and four concentrations (0, 15, 30, 60 ppm) of Cadmium sulfate solutions on seed g...
متن کاملChromatographic determination of changes in pigments in spinach (Spinacia oleracea L.) during processing.
The content of individual chlorophyll and carotenoid pigments is determined in three spinach varieties (Lorelei, Springfield, and Ballet) after processing. Raw spinach and spinach that is steam-blanched for 3, 9, or 15 min is stored frozen at -24 degrees C for 6 months. In addition, spinach is air-dried at 75 degrees C, packed in atmospheric air or nitrogen, and stored at ambient temperature fo...
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 کاملBioremediation potential of spinach (Spinacia oleracea L.) for decontamination of cadmium in soil
Greenhouse pot culture studies were conducted to evaluate the bioremediation potential of spinach for removal of cadmium. The results indicated that spinach was able to take up cadmium in substantial quantity in the shoot. There were no visual cadmium toxicity effects on spinach and no significant reduction in the dry matter yield up to 20 μg g cadmium. Significant growth retardation of fenugre...
