“…These properties include resilience, elasticity, abrasion and impact resistance, efficient heat dispersion and malleability at cold temperatures (Cataldo, 2000;Cornish, 2001a). Although synthetic rubbers, such as styrene-butadiene or acrylonitrile-butadiene co-polymers, are commercially produced to levels similar to natural rubber, none of them match the price-performance ratio of natural rubber.…”

“…Although synthetic rubbers, such as styrene-butadiene or acrylonitrile-butadiene co-polymers, are commercially produced to levels similar to natural rubber, none of them match the price-performance ratio of natural rubber. The unique properties of natural rubber make it essentially irreplaceable for many applications, such as heavy-duty tires for trucks, buses and airplanes, as well as latex products for medical applications (Cornish, 2001a). While some plants can produce other types of polyisoprenes, none of them have material properties or value similar to Hevea rubber.…”

“…rubber granules with associated proteins and lipids; Asawatreratanakul et al, 2003), and it has not been established whether the rubber particles contain the sought-for long-chain rubber polymerase or another protein or cofactor that enables the expressed cis-prenyltransferase to produce long-chain rubber. Studies are complicated by the fact that the dominant proteins attached to rubber particles differ radically in number, size and predicted function based on sequence comparisons between the various plant species that produce rubber (van Beilen and Poirier, 2007a;Cornish, 2001a). Two main problems are associated with the production of rubber from H. brasiliensis.…”

SummaryPlants produce a range of biopolymers for purposes such as maintenance of structural integrity, carbon storage, and defense against pathogens and desiccation. Several of these natural polymers are used by humans as food and materials, and increasingly as an energy carrier. In this review, we focus on plant biopolymers that are used as materials in bulk applications, such as plastics and elastomers, in the context of depleting resources and climate change, and consider technical and scientific bottlenecks in the production of novel or improved materials in transgenic or alternative crop plants. The biopolymers discussed are natural rubber and several polymers that are not naturally produced in plants, such as polyhydroxyalkanoates, fibrous proteins and poly-amino acids. In addition, monomers or precursors for the chemical synthesis of biopolymers, such as 4-hydroxybenzoate, itaconic acid, fructose and sorbitol, are discussed briefly.

“…However, in possible parents, only one allele can be observed in PB 310 ('c') and A 2 -A 5 ('d') and, therefore, these five samples can be ruled out as Tri-1's 2n gamete source. Marker RUB 184 can amplify alleles 'abc' in Tri-1; while only allele 'a' can be observed in A 1 , A 6 -A 8 (Figure 2d). Thus, all 14 candidate male parent clones can be excluded as the origin of 2n gametes of Tri-1.…”

“…Demand for rubber is increasing with economic development; however, the regions where rubber trees are planted are limited due to the stringent environmental requirements for their growth [7]. In addition, alternatives to natural rubber are still limited because synthetic rubber produced from petroleum does not match its resilience, elasticity, and abrasion resistance [8,9].…”

Eight triploids were screened among offspring of the rubber tree clone GT1 × different clones by flow cytometry and chromosome counting. Twenty-five simple sequence repeat (SSR) markers were screened to identify the origin of 2n gametes, to determine the male parents of these triploids, and to evaluate the mechanism of 2n gamete formation using band configurations and microsatellite DNA allele counting peak ratios (MAC-PR). The results showed that 2n gametes originated from the maternal rubber tree clone GT1, contributing the extra genome copy present in the triploids. It was confirmed that GT1 is able to produce a 2n megagametophyte spontaneously. Many male parents were shown to provide pollen for formation of triploid rubber trees, including clones RRIC 103, Yunyan 277-5, and three other clones. The second division restitution (SDR) was likely the main mechanism involved in formation of megagametophytes in GT1, as the rate of maternal heterozygosity restitution (HR) of all eight triploids varied from 27.78% to 75.00%, with a mean of 51.46%, and all 25 markers varied from 0% to 100%, with a mean of 51.69%. Elucidation of the origin and formation of 2n gametes will help optimize further sexual hybridization of polyploid rubber trees.

Guayule ( Parthenium argentatum ) is a rubber‐producing woody shrub native to the Chihuahuan Desert of northern Mexico and Texas. Guayule produces linear, high molecular weight natural rubber that can have physical properties and applications equivalent to those of Hevea ( Hevea brasiliensis ) rubber. Guayule rubber can be extracted as a solid bulk polymer or as a latex. Guayule also is one of very few rubber‐producing plants to have ever been used commercially for rubber production. Although guayule rubber was commercially produced in the early part of the last century, more recent efforts to reinstate production have not led to commercial success because the production costs of bulk rubber were too high to permit direct competition with Hevea rubber. Guayule commercialization has been revitalized in recent years by use of the plant to produce low protein hypoallergenic latex, a higher value rubber raw material.
