The Enzymatic Synthesis of Rubber Polymer in Parthenium argentatum Gray [PDF]
Plant Physiology, 1990 Washed rubber particles isolated from stem homogenates of Parthenium argentatum Gray by ultracentrifugation and gel filtration on columns of LKB Ultrogel AcA34 contain rubber transferase which catalyzes the polymerization of isopentenyl pyrophosphate into rubber polymer.

Genetic variability within and between apomictic Guayule (Parthenium argentatum Gray) lines
, 1994 Guayule (Parthenium argentatum Gray), a semidesert shrub was evaluated as a potential rubber crop. Since polyploid guayule reproduces by apomixis, progeny of individual plants should duplicate the characteristics of their parent. This study was conducted

Biopesticide Activity of Guayule Resin
Plants, 2022 The extensive use of synthetic pesticides has created considerable concern for both human health and the environment, which has prompted the search for safer alternatives, such as the resin of guayule (Parthenium argentatum).

Plant Biotechnology Journal, Volume 23, Issue 12, Page 5654-5676, December 2025.ABSTRACT Taraxacum kok‐saghyz (TKS) synthesises natural rubber (NR) and inulin using sucrose as a carbon source. However, molecular mechanisms regulating inulin and NR accumulation remain largely unclear. Here, we report the generation of double‐gene homozygous mutants, 1‐sst1‐fft, by simultaneously knocking out two key genes responsible for inulin ...

Polymer Engineering &Science, Volume 65, Issue 10, Page 5109-5123, October 2025.Suspending old certainties, NMR now hints at a constant linear polyisoprene core whose corona morphs with pH tight, multilamellar in acidic latex, loose and hydrated after ammonia. ABSTRACT How reliable is our century‐old understanding of natural‐rubber latex (NRL) when examined through the lens of modern analytical techniques, such as nuclear magnetic

Plant Biotechnology Journal, Volume 17, Issue 11, Page 2041-2061, November 2019., 2019 Summary Natural rubber (NR) is a nonfungible and valuable biopolymer, used to manufacture ~50 000 rubber products, including tires and medical gloves. Current production of NR is derived entirely from the para rubber tree (Hevea brasiliensis). The increasing demand for NR, coupled with limitations and vulnerability of H. brasiliensis production systems,

Stress-Induced Proteins in Parthenium argentatum Leaves
Biologia plantarum, 2003 We have analyzed the stress-associated proteins in a high-rubber-yielding guayule (Parthenium argentatum Gray cv. 11591) leaves. Protein profiles in leaf fractions, resolved by SDS-PAGE and visualized by Coomassie Brilliant Blue staining, were different under various stresses.

Macromolecular Materials and Engineering, Volume 310, Issue 6, June 2025.For the first time, peroxide cross‐linked solid green guayule natural rubber is shown to exhibit highly reproducible cyclic strain‐induced crystallization behavior, consistent with its tensile properties. Using in situ tensile testing and synchrotron wide‐angle X‐ray diffraction over two cycles, this study enhances understanding of its mechanical ...
