Biochemical characterization and cellular localization of 11S type storage proteins in olive (Olea europaea L.) seeds.
The composition of seed storage proteins (SSPs) in olive endosperm and cotyledon has been analyzed. Precursor forms of these proteins are made up of individual proteins, which have been purified to homogeneity and further named p1-p5 (20.5, 21.5, 25.5, 27.5, and 30 kDa, respectively). N-terminal sequences of p1 and p2 proteins displayed relevant homology to the basic subunit of the 11S family o...

در این بررسی جوانه های انتهایی و جانبی (قطعات گره دارای دو جوانه) از پایه های برتر موجود در رویشگاه طبیعی زیتون از جمله طارم، منجیل، رودبار و گرگان و نیز پایه های موجود در موسسه محل تحقیق در فصول مختلف سال برداشت شد و پساز اعمال تیمارهای ضدعفونی کننده با دو عامل کلرور مرکوریک و هیپوکلریت سدیم و نیز تلفیقی از آنها، روی دو محیط کشت پایه MS و OM استقرار یافتند. نمونه های مستقر شده جهت تحریک شاخه ...
متن کاملFractional Isolation and Structural Characterization of Hemicelluloses from Soybean Hull
Hemicellulosic fractions were extracted from soybean hull with various concentrations of NaOH at 50 °C for 5 h. The chemical compositions and physicochemical properties were determined by high performance anion exchange chromatography (HPAEC), Fourier transform infrared spectroscopy (FT-IR), thermogravimetric analyzer (TGA), and C and 2D nuclear magnetic resonance (NMR) analysis. The crystallin...
متن کاملAnalysis and quantification of flavonoidic compounds from Portuguese olive (Olea europaea L.) leaf cultivars.
Twenty three samples of 18 Portuguese olive leaf cultivars were analysed by a reversed-phase HPLC/DAD procedure and eight flavonoidic compounds were identified and quantified (luteolin 7,4'-O-diglucoside, luteolin 7-O-glucoside, rutin, apigenin 7-O-rutinoside, luteolin 4'-O-glucoside, luteolin, apigenin and diosmetin). Luteolin 7,4'-O-diglucoside and luteolin 4'-O-glucoside were identified by H...
متن کاملStructural Characterization of Hemicelluloses from Bamboo Culms (neosinocalamus Affinis)
Dewaxed bamboo culms (Neosinocalamus affinis) were sequentially extracted with distilled water and 70% ethanol at 80 oC for 3 h, 0.2 and 0.5 M NaOH, 70% ethanol containing 0.6 M NaOH, and 1.0 and 2.0 M NaOH at 50 oC for 3 h using a solid to liquid ratio of 1:25 (g/mL). The hemicellulosic fractions obtained were characterized by high performance anion exchange chromatography (HPAEC), gel permeat...
