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 کاملIn Vitro Characterization of Apomictic Reproduction in Guayule
Guayule (Parthenium argentatum Gray, Asteraceae) is a latex-producing perennial desert shrub native to southwestern Texas and north central Mexico. It is potentially an economically viable new crop for the desert Southwest, with the advantages of having low water requirements and producing non-allergenic latex (Thompson and Ray 1988). Diploid guayule plants reproduce predominantly sexually, and...
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...
