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 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 کاملMagnesium ion regulation of in vitro rubber biosynthesis by Parthenium argentatum Gray.
Natural rubber is produced by a rubber transferase (a cis-prenyltransferase). Rubber transferase uses allylic pyrophosphate to initiate the rubber molecule and isopentenyl pyrophosphate (IPP) to form the polymer. Rubber biosynthesis also requires a divalent metal cation. Understanding how molecular weight is regulated is important because high molecular weight is required for high quality rubbe...
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 کاملEffect of 2-(3,4-Dichlorophenoxy)-triethylamine on the Synthensis of cis-Polyisoprene in Guayule Plants (Parthenium argentatum Gray).
The application of 2-(3,4-dichlorophenoxy)-triethylamine to guayule (Parthenium argentatum Gray var 593) plants results in a 2-fold stimulation of rubber synthesis and a 1.5- to 3-fold increase in mevalonic acid kinase, isopentenyl pyrophosphate isomerase, and rubber transferase. The increase in these enzymic activities accounts in part for the chemical induction of rubber synthesis.
