Biochemical regulation of rubber biosynthesis in guayule (Parthenium argentatum Gray)
Natural rubber is an irreplaceable raw material vital to industry, transportation, medicine and defense. It is largely produced from clonal plantations of Hevea brasiliensis in southeastern Asia. Temperate-zone rubber-producing crops are greatly desired to increase biodiversity, protect supplies, and provide a safe natural-rubber alternative for the large numbers of people suffering from Type I...
متن کاملImpairment of Photorespiratory Carbon Flow into Rubber by the Inhibition of the Glycolate Pathway in Guayule (Parthenium argentatum Gray).
Cut shoots of guayule (Parthenium argentatum Gray) were treated with four inhibitors of the glycolate pathway (alpha-hydroxypyridinemethanesulfonic acid; isonicotinic acid hydrazide, glycine hydroxamate, and amino-oxyacetate, AOA) in order to evaluate the role of photorespiratory intermediates in providing precursors for the biosynthesis of rubber. Photorespiratory CO(2) evolution in guayule le...
متن کاملA century of guayule: Comprehensive Genetic Characterization of the Guayule (Parthenium argentatum A. Gray) USDA Germplasm Collection
The fragility of a single-source, geographically concentrated supply of natural rubber, a critical material of the modern economy, has brought guayule ( Parthenium argentatum A. Gray) to the forefront as an alternative source of natural rubber. The improvement of guayule for commercial-scale production has been limited by the lack of genomic tools and well-characterized genetic resources requ...
متن کاملTranscriptome and gene expression analysis in cold-acclimated guayule (Parthenium argentatum) rubber-producing tissue.
Natural rubber biosynthesis in guayule (Parthenium argentatum Gray) is associated with moderately cold night temperatures. To begin to dissect the molecular events triggered by cold temperatures that govern rubber synthesis induction in guayule, the transcriptome of bark tissue, where rubber is produced, was investigated. A total of 11,748 quality expressed sequence tags (ESTs) were obtained. T...
متن کاملA novel cDNA from Parthenium argentatum Gray enhances the rubber biosynthetic activity in vitro.
Natural rubber (cis-1,4-polyisoprene) is an isoprenoid compound produced exclusively in plants by the action of rubber transferase. Despite a keen interest in revealing the mechanisms of rubber chain elongation and chain length determination, the molecular nature of rubber transferase has not yet been identified. A recent report has revealed that a 24 kDa protein tightly associated with the sma...
