A 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...

Rubber tree breeding and the dissemination of planting material for plantations are closely linked to propagation methods. Since the progress made by switching from multiplication by seed to propagation by bud...
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 کاملChloride-ion stimulation of the tonoplast H+-translocating ATPase from Hevea brasiliensis (rubber tree) latex. A dual mechanism.
The effect of Cl- and other anions on the tonoplast H+-translocating ATPase (H+-ATPase) from Hevea brasiliensis (rubber tree) latex was investigated. Cl- and other anions stimulated the ATPase activity of tightly sealed vesicles prepared from Hevea tonoplast, with the following decreasing order of effectiveness: Cl- greater than Br- greater than SO4(2-) greater than NO3-. As indicated by the ch...
متن کاملInsights into rubber biosynthesis from transcriptome analysis of Hevea brasiliensis latex.
Hevea brasiliensis is the most widely cultivated species for commercial production of natural rubber (cis-polyisoprene). In this study, 10,040 expressed sequence tags (ESTs) were generated from the latex of the rubber tree, which represents the cytoplasmic content of a single cell type, in order to analyse the latex transcription profile with emphasis on rubber biosynthesis-related genes. A tot...
