Microsomal membrane preparations from the developing endosperm of castor bean (Ricinus communis) catalysed transfer oleate [14C]oleoyl-CoA to phosphatidylcholine (PtdCho). In presence NADH, radioactive ricinoleate (12-hydroxyoctadec-9-enoate) was synthesized [14C]oleate, and this largely recovered in PtdCho as free fatty acid. The addition unlabelled ricinoleoyl-CoA these incubation mixtures did not increase low [14C]ricinoleate concentration found acyl-CoA fraction nor decrease acid, thus...
The violation of Baryon Number, $\mathcal{B}$, is an essential ingredient for the preferential creation matter over antimatter needed to account observed baryon asymmetry in universe. However, such a process has yet be experimentally observed. HIBEAM/NNBAR %experiment program proposed two-stage experiment at European Spallation Source (ESS) search number violation. will include high-sensitivity searches processes that violate by one or two units: free neutron-antineutron oscillation...
A method for determination of lead, cadmium, zinc, copper, and iron by atomic absorption spectrometry (AAS) after microwave digestion was subjected to a collaborative study in which 16 laboratories participated [including users inductively coupled plasma (ICP) ICP-mass (MS)]. The types samples included the were minced fish, wheat bran, milk powder, bovine pig liver, mushroom, 2 simulated diets, muscle; last 4 certified reference materials. These analyzed as single (4 samples), double blind...
Abstract Transgenic potato (Solanum tuberosum cv Désirée) plants overexpressing a soybean (Glycine max) type 1 sterol methyltransferase (GmSMT1) cDNA were generated and used to study biosynthesis in relation the production of toxic glycoalkaloids. displayed an increased total level both leaves tubers, mainly due levels 24-ethyl sterols isofucosterol sitosterol. The higher was increases free esterified sterols. However, cholesterol, nonalkylated sterol, decreased. Associated with this...
Embryos of Cuphea lanceolata have more than 80 mol% decanoic acid (‘capric acid’) in their triacylglycerols, while this fatty is virtually absent phosphatidylcholine (PtdCho). Seed development was complete 25-27 days after pollination, with rapid triacylglycerol deposition occurring between 9 and 24 days. PtdCho amounts increased until day 15 pollination. Analysis embryo lipids showed that the diacylglycerol (DAG) pool consisted mainly long-chain molecular species, a very small amount mixed...
The biosynthesis and maturation of glucocerebrosidase were studied in firbroblasts from patients with the neurological non-neurological forms Gaucher disease control cells. In fibroblasts precursor (62–63 kDa), observed after a short pulse [35S]methionine, was converted during chase period to 66-kDa intermediate form and, finally, 59-kDa mature protein. phenotype (type 1) same biosynthetic seen as fibroblasts. These correspond three-banded pattern type 1 fibroblast extracts analysed by...
Potato tubers naturally contain a number of defense substances, some which are major concern for food safety. Among these substances the glycoalkaloids and calystegines. We have here analyzed levels (α-chaconine α-solanine) calystegines (A3, B2, B4) in potato subjected to mechanical wounding, light exposure, or elevated temperature: stress treatments that known anticipated induce glycoalkaloid levels. Basal varied between cultivars. Wounding but not heat, increased tuber levels, relative...
The major b-type cytochrome in microsomal membrane preparations from developing endosperm of castor bean (Ricinus communis) was b5. Cytochrome P-450 also present. membranes had delta 12-hydroxylase activity and catalysed the NAD(P)H-dependent hydroxylation oleate to yield ricinoleic acid. CO no effect on hydroxylase activity. Rabbit polyclonal antibodies were raised against hydrophilic b5 fragment purified cauliflower (Brassica oleracea) floret microsomes. anti-(cytochrome b5) IgG inhibited...
The β-glucosidase activity in spleen from control subjects and patients with different clinical phenotypes of Gaucher's disease was characterized. occurrence a soluble non-specific neutral pH optimum two membrane-associated β-glucocerebrosidases an acid demonstrated. can be distinguished on the basis their ability to react anti-(placental β-glucocerebrosidase) antibodies bound protein-A – Sepharose 4B beads. One splenic (form I) is precipitated by immobilized other II) not. forms also differ...
Aphids are pests on many crops and depend plant phloem sap as their food source. In an attempt to find factors improving resistance against aphids, we studied the effects of overexpression down-regulation lipoxygenase gene LOX2.2 in barley (Hordeum vulgare L.) performance two aphid species. A specialist, bird cherry-oat (Rhopalosiphum padi a generalist, green peach (Myzus persicae Sulzer) were studied. overexpressing lines showed up-regulation some other jasmonic acid (JA)-regulated genes,...
The effect of infestation by the birdcherry‐oat aphid ( Rhopalosiphum padi L.), on induction PR‐proteins was investigated in barley Hordeum vulgare using lines susceptible or resistant to R. padi. PR‐1a (unknown function), PR‐5a (acidic thaumatin) and peroxidase (EC 1.11.1.7) were not affected, whereas one chitinase 3.2.1.14) 4 β ‐1,3‐glucanases 3.2.1.39) induced treatment. In breeding line CI 16145, but cultivar Golf, accumulation basic two acidic increased with time from 2 until 11 days...
The effects of infestation by the bird cherry-oat aphid (BCA), (Rhopalosiphum padi L) and Russian wheat (RWA) (Diuraphis noxia Mordvilko) on callose deposition transcription genes related to accumulation were investigated in barley (Hordeum vulgare L. cv. Clipper). BCA, which gives no visible symptoms, induced very limited deposition, even after 14 days infestation. In contrast, RWA, causes chlorosis, white yellow streaking leaf rolling, already 24 h longitudinal veins. was pronounced 72 h,...
Steroidal glycoalkaloids (SGA) are sterol-derived neurotoxic defence substances present in several members of the Solanaceae. In potato (Solanum tuberosum), high SGA levels may render tubers harmful for consumption. Tuber depend on genetic factors, and can increase as a response to certain stresses environmental conditions. To identify genes underlying cultivar variation tuber levels, we investigated two cultivars differing their accumulation during wounding or light exposure; known...
