Application o f [6 14C]or [7-14C]nicotinic acid to parsley cell suspension cultures led to the accumulation of labelled nicotinamide m ononucleotide, nicotinamide adenine dinucleotide, nicotinamide N-riboside, nicotinamide and nicotinic acid, indicating the operation of the pyridine nucleotide cycle in these cells. A s main conjugates, nicotinic acid N-glucoside and nicotinic acid glucose ester...

Root colonization by plant-growth-promoting rhizobacteria (PGPR) can be increased depending on the type of rhizosphere. The aim of the present study was to determine fluorescent Pseudomonad diversity in lettuce, parsley, arugula and chicory. Roots from these rhizospheres were sampled at different properties of small commercial producers in Campinas, state of Sao Paulo, Brazil. In the diversity ...

Trans-Caffeoyl-CoA 3-O-methyltransferase is involved in the reinforcement of the plant cell wall under conditions that trigger the disease resistance response (Pakusch, A.-E., Kneusel, R.E., and Matern, U. (1989) Arch. Biochem. Biophys. 271, 488-494). Partial amino acid sequences of the enzyme from cultured parsley cells that had been treated with a crude elicitor were identified (Pakusch, A.-E...

increased serum uric acid is known to be a major risk related to the development of several oxidative stress diseases. the aim of this study was to investigate the effect of parsley, quercetin and kaempferol on serum uric acid levels, liver xanthine oxidoreductase activity and two non-invasive biomarkers of oxidative stress (total antioxidant capacity and malondialdehyde concentration) in norma...

background: the sources of radioactivity in the environment have natural, terrestrial and extraterrestrial, and anthropogenic origins. plants may get radioactive nuclides in two ways: (i) by the deposition of radioactive fallout, (ii) by absorption from the soil. materials and methods: the concentrations of the natural radionuclides (226ra, 228ra, 40k) and the artificial radionuclide (137cs) in...

in this study, parsley was dried using three drying methods: hot air (50, 60 ‎and 70 ºc), microwave (90, 180, 360, 600 and 900 w) and a combination of ‎hot air – microwave (60ºc and 360w). selection of the optimum levels for ‎drying in combination method took place with quality tests of dried ‎samples. the drying data of parsley with hot air and microwave methods ‎was fitted with eight models: ...

Rooted quivers are quivers that do not contain A∞ ≡ ··· → • → • as a subquiver. The existence of flat covers and cotorsion envelopes for representations of these quivers have been studied by Enochs et al. The main goal of this paper is to prove that flat covers and cotorsion envelopes exist for representations of A∞. We first characterize finitely generated projective representations of A∞. We ...

7 An antimatroid is a family of sets such that it contains an empty set, and it is accessible and closed under union of sets. An antimatroid is an ‘antipodal’ concept of matroid. 9 We shall show that an antimatroid is derived from shelling of a poset if and only if it does not contain a minor isomorphic to S7 where S7 is the smallest semimodular lattice that is not 11 modular. It is also shown ...

Soluble enzyme preparations from irradiated cell suspension cultures of parsley (Petroselinum hortense Hoffm.) catalyse the conversion of flavanone to flavone, dihydroflavonol and flavonol. These reactions require 2-oxoglutarate, Fe2+ and ascorbate as cofactors. In the presence of these cofactors conversion of dihydroflavonol to flavonol was also observed. With this system in vitro biosynthesis...

Dill (Anethum graveolens L.) and parsley (Petroselinum crispum Mill.) were dried by using sun and oven (50oC) drying methods. Oven drying decreased the drying time approximately 50% when compared to the sun drying method for both herbs. K, Ca, P, Mg and Na were the most abundant elements in dill and parsley samples. Oven-dried samples had higher mineral values than that of the su...
