TECHNOLOGICAL PROPERTIES OF LATEX AND NATURAL RUBBER OF Hevea brasiliensis CLONES
Rubber industry has increased the requirements for quality and uniformity of natural rubber produced in Brazil. Technological properties of latex and natural rubber of clones GT 1, PB 235, IAN 873 and RRIM 600 [Hevea brasiliensis (Willd. Former Adr. de Juss.) Muell.Arg] were evaluated by standard methods of the dry rubber content (DRC%), percentage of nitrogen (N%) and percentage of ashes (ASH%...
متن کاملAngiogenic Properties of Natural Rubber Latex Biomembranes and The Serum Fraction of Hevea brasiliensis
The angiogenic properties of natural rubber were evaluated in this work. We have used the chick chorioallantoic membrane assay (CAM) as a model to investigate the influence of the heating on biological activity in rubber membranes and in non rubber fraction as well. Results showed that natural rubber membranes can induce vascularization. It was observed that angiogenesis activity was maximum wh...
متن کاملA Stimulator Protein of Rubber Biosynthesis from Hevea brasiliensis Latex
A rubber biosynthesis stimulator protein (RBSP)from the C-serum of Hevea brasiliensis latex was purified and characterised. This proteinaceous factor stimulates the incorporation of isopentenyl diphosphate into rubber and thereby enhances the rate of rubber biosynthesis. The heat stable RBSP is shown to have a molecular weight of 13 068 Da by mass spectroscopy. Amino acid sequence of peptide fr...
متن کاملMetabolic routes affecting rubber biosynthesis in Hevea brasiliensis latex
The cytosolic mevalonate (MVA) pathway in Hevea brasiliensis latex is the conventionally accepted pathway which provides isopentenyl diphosphate (IPP) for cis-polyisoprene (rubber) biosynthesis. However, the plastidic 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway may be an alternative source of IPP since its more recent discovery in plants. Quantitative RT-PCR (qRT-PCR) expression profiles ...
متن کاملIdentification of clinically relevant cross-sensitization between Soliadgo virgaurea (goldenrod) and Hevea brasiliensis (natural rubber latex).
BACKGROUND Solidago virgaurea (goldenrod) is a perennial weed from which no allergens have been identified. A high latex content in its leaves has been reported. Although not an airborne allergen, it may be an important occupational sensitizer. OBJECTIVE To identify allergenic proteins in goldenrod and to determine whether they cross-react with Hevea brasiliensis latex. METHODS Potential cr...
