Chemical Composition of Guayule (Parthenium argentatum Gray) Wax

Journal of Wood Chemistry and Technology, 1994
Abstract Commercialization of guayule holds promise not only as an additional source of natural rubber but also for the utilization of its byproducts viz. wax, resin and bagasse. Hence interest in guayule has been revived once again. The present paper discusses the isolation, characterization and possible applications of one of the byproducts - guayule

Essential leaf oils of Parthenium argentatum A. Gray

Journal of Agricultural and Food Chemistry, 1979
When guayule (Parthenium argentatum) is processed for rubber the leaves are discarded. Essential oils from guayule leaves were therefore steam distilled and the major monoterpenes were examined by gas chromatography-mass spectrometry. Alpha-pinene, camphene, beta-pinene, sabinene, beta-myrcene, limonene, terpinolene, beta-ocimeme and ocimene were ...

Potent Contact Allergen in the Rubber Plant Guayule ( Parthenium argentatum )

Science, 1981
Chemical and dermatotoxicological investigations of the natural and processed resin of the Mexican rubber plant, guayule ( Parthenium argentatum ), has established the presence of a sesquiterpene cinnamic acid ester (guayulin A) that is a potent elicitor of allergic contact dermatitis in experimental animals.

In vitro propagation of guayule (Parthenium argentatum) ? a rubber yielding shrub

Plant Cell Reports, 1989
Nodal explants (0.5 to 0.8 cm long) isolated from 2-year old shrubs of guayule, Parthenium argentatum Gray, when cultured on MS medium supplemented with different concentrations of KN, BAP, 2,4-D, 2,4-D + BAP, NAA and NAA + BAP produced callus tissues and shoots simultaneously with varying frequencies.

Histochemical Techniques to Localize Rubber in Guayule (Parthenium ArgentatumGRAY)

Stain Technology, 1986
There are few histochemical techniques for staining rubber in the cells of guayule. With regard to specificity, clarity and retention of the stain we found staining with oil red O or iodine-potassium iodide for bright field, and a combination of oil red O and dansyl chloride for epifluorescence microscopy to be the best methods.

On the Inheritance of Apomixis in Parthenium argentatum

Botanical Gazette, 1950
1. In feral guayule the diploids (2n = 36) reproduce sexually, but polyploids are facultative apomicts. A fertile polyhaploid with the diploid number of chromosomes but facultatively apomictic in its reproduction was crossed with a diploid. If the polyhaploid was used as a female, the following progeny classes resulted: maternals, diploid F1, triploids,

In vitro propagation of guayule (Parthenium argentatum gray)

Plant Science Letters, 1983
Abstract A method is described for the rapid propagation of guayule plants in vitro. Shoot multiplication from excised buds wwas timulated by the presence of benzyladenine (BA) and concentrations of 1.0 mg l−1 encouraged shoot proliferation without greatly decreasing shoot length.

EVIDENCE FOR NATURAL HYBRIDITY BETWEEN GUAYULE (PARTHENIUM ARGENTATUM) AND MARIOLA (PARTHENIUM INCANUM)

American Journal of Botany, 1944
THE ACCELERATED investigations of Guayule (Par-thenium argentatum) in an attempt to mold it into a stable crop plant have quickly revealed a number of complicated problems for the plant breeder. Some of these would be encountered in working similarly with almost any wild plant species, while others are seemingly peculiar to Guayule.

A bicistronic transgene system for genetic modification of Parthenium argentatum

Plant Biotechnology Reports, 2018
Parthenium argentatum (guayule) was transformed with a bicistronic transgene containing a viral 2A cleavage sequence. The transgene includes the coding sequences of two key enzymes of the mevalonate pathway, 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) and farnesyl pyrophosphate synthase (FPPS), involved in rubber biosynthesis.
