Smnmary. Washed whole chloroplasts of Spinacia oleracea isolated and assayed in a tris (hydroxymethyl aminomethane)-HCl bu'ifered sucrose solution exhibited low dark CO.2 fixing activity, whereas washed whole chloroplasts isolated in the same buffer but assayed in that ibuffer without sucrose exh;ibited much greater dark CO2 'fixing activity. The lowered activity could be attributed to the impe...
The dioecious genus Spinacia is thought to include two wild relatives (S. turkestanica Ilj. and S. tetrandra Stev.) of cultivated spinach (S. oleracea L.). In this study, nuclear and chloroplast sequences from 21 accessions of Spinacia germplasm and six spinach cultivars or lines were subjected to phylogenetic analysis to define the relationships among the three species. Maximum-likelihood sequ...
Spinacia oleracea, Arum maculatum, Alanine: Aldehyde Aminotransferase, Amine-Biosynthesis, Subcellular Localization, Mitochondria L-Alanine: aldehyde aminotransferase occurs ubiquitously in higher plants. The enzyme catalyzes the reaction: L-alanine + monoaldehyde -> monoamine + pyruvate; it is responsible for the formation of aliphatic plant amines and involved in the biosynthesis of hemlock a...
Three fungi newly intercepted from importing plants were identified in 2004. They were Ascochyta chrysanthemi on Lactuca sativa from China, A. spinaciicola on Spinacia oleracea from Denmark, and Leptosphaerulina australis on Brassica oleracea var. capitata from China. The characters of these fungi were described and illustrated.
Phytoremediation is one of the cleanup methods of polluted soil that is possible accumulation of heavy metals in plant tissues, exclusion of these elements from contaminated soil. Therefore, to achievement the objective, this research was done in pot culture using completely randomized design at the University of Birjand in 2011. Two species Spinacia oleracea and Lepidium sativum were used to r...
یک آزمایش گلدانی در هوای آزاد در بستر شن+ کوکوپیت (نسبت 80:20) انجام شد تا فعالیت آنزیم نیترات ردوکتاز و تجمع نیترات در ریشه ها و برگ های پانزده توده بومی اسفناج ایرانی (spinacia oleracea) در مراحل مختلف نمو گیاه مورد بررسی قرار گیرد. گیاهان در سه دوره زمانی از مراحل 22، 30 و 38 روز پس از ظهور اولین برگ های حقیقی و قبل از گلدهی مورد آزمایش قرار گرفتند. نتایج نشان دادند بیشترین فعالیت آنزیم نیتر...
The decrease of the number of ring nitrogen atoms of 2-benzylamino-4-methyl-6-trifluoromethyl-1,3,5-triazines on herbicidal activity and inhibition of photosynthetic electron transport (PET) was assayed using thylakoids from Spinacia oleracea or atrazine-resistant Chenopodium album. Three 2-benzylamino-4-methyl-6-trifluoromethyl-1,3,5-triazines, nine pyrimidines with a benzylamino-, methyl- and...
East Calcutta Wetland (ECW) is an example of wise use of cities solid and liquid waste through integrated resource recovery, mainly for pisciculture, vegetable as well as paddy cultivation and manure production. Amaranthus caudatus, Amaranthus blithum and Spinacia oleracea grown at ECW were analyzed for their accumulation of elements using Energy Dispersive X Ray Fluorescence (EDXRF) and compar...
A low-molecular-weight protein catalysing the transfer of phosphatidylcholine from liposomes to mitochondria and chloroplasts has been isolated from spinach (Spinacia oleracea) by chromatography on Sephadex G-75.
