Genomics of Rubber Biosynthesis in Hevea brasiliensis
, 2020 The Hevea brasiliensis rubber tree is the largest commercial producer of natural rubber. The ability to synthesize a naturally occurring polymer is one of the main attractions of studying latex rubber biosynthesis. Natural rubber consists of high molecular weight cis-polyisoprene, a branch product of the isoprenoid network, which is synthesized by ...

The Biosynthesis of Natural Rubber
Journal of Plant Physiology, 1990Summary The biosynthesis of natural rubber, Z-polyisoprene, is reviewed in the light of the recent elucidation of its detailed chemical structure. Natural rubber is homologous with a group of the polyprenols. The identity of the putative rubber transferase isolated from Hevea latex serum and guayule tissue as well as the published assay for rubber ...

Molecular Mechanisms of Natural Rubber Biosynthesis
Annual Review of Biochemistry, 2020Natural rubber (NR), principally comprising cis -1,4-polyisoprene, is an industrially important natural hydrocarbon polymer because of its unique physical properties, which render it suitable for manufacturing items such as tires.

The Plant Journal, 2015 SummaryTwo protein families required for rubber biosynthesis in Taraxacum brevicorniculatum have recently been characterized, namely the cis‐prenyltransferases (TbCPTs) and the small rubber particle proteins (TbSRPPs). The latter were shown to be the most abundant proteins on rubber particles, where rubber biosynthesis takes place. Here we identified a

Structure and Biosynthesis Mechanism of Rubber from Fungi
Rubber Chemistry and Technology, 1990 Abstract The structure of both terminal units and alignment of the isoprene units give conclusive evidence for the initiation and termination mechanisms of rubber formation in fungi. As shown in Figure 4, the polymerization is estimated to start from trans, trans-farnesyl pyrophosphate and proceeds by successive condensation of IPP to form ...

Guayule biosynthesizes and accumulates rubber particles predominantly in epithelial cells in the parenchyma tissue, and this biosynthesis and accumulation is accompanied by remodeling of the roles of epithelial cells. The mechanism underlying the biosynthesis and accumulation of large quantities of rubber particles and resin in the parenchyma tissue of

The problem of how rubber is synthesized in the plant has been divided into two portions:(i) the nature of the monomer used and how this monomer is synthesized, and (ii) the nature of the polymerization reaction by which the monomer is transformed to rubber.

The stereochemistry of rubber biosynthesis
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1966Abstract The stereochemistry of the formation of natural rubber and trans-trans-farnesyl pyrophosphate in latex has been studied in vitro using [2-14C-(4R)-4-3H1] and [2-14C-(4S)-4-3H1]mevalonates as substrates. The proton eliminated from C-2 of isopentenyl pyrophosphate during the formation of farnesyl pyrophosphate in latex has the ...

Molecular Genetic Analysis of Natural Rubber Biosynthesis
Russian Journal of Plant Physiology, 2021Natural rubber (cis-1,4-polyisoprene) is an irreplaceable starting material for thousands of products, many of which are absolutely essential, in particular for modern medicine. Rubber is found in the latex of an aqueous emulsion contained in the specialized structures of rubber-producing plants, laticifers.

New aspects of rubber biosynthesis
Botanical Journal of the Linnean Society, 1987New aspects of rubber biosynthesis. Following a review of the site of rubber biosynthesis in Hevea brasiliensis and Parthenium argentalum, evidence is given for the initiation of polyisoprene molecules from (ranMerpenoid precursors including geranylgeranyl pyrophosphate.
