“…Related literature explored the storage temperature of guayule branches. It was found that higher temperature will accelerate the decline rate of latex content and molecular weight, while storing latex at 4 °C will slow down this process [ 32 , 33 ], lower temperature will cause the water to freeze and cause the loss of the water phase, which may cause the rubber particles in the latex to irreversibly coagulate [ 33 , 34 ]. Considering that both latexes are present in plant tissues (TKS roots, guayule branches), they have a relatively high similarity.…”

“…Acetyl Co-A, ATP and NADPH are ubiquitous cellular metabolites derived either from stroma saccharides or arising directly from photosynthesis (Ramachandra Reddy and Rama Das 1995). In a wide range of plant species, experimental manipulations that enhanced photosynthesis, increased the pace of secondary metabolite production (Cornish et al 2000). Previous studies from our laboratory have shown the ability of guayule to acclimate the key photosynthetic enzymes and to improve the rate of photosynthesis with low night temperature treatment of 15°C in a controlled-growth environment, that may contribute to an increase in the carbon flow from the leaves to the stem for enhanced rubber production (Sundar and Ramachandra Reddy 2000, 2001, 2003.…”

Low temperature-induced changes in antioxidative metabolism in rubber-producing shrub, guayule (Parthenium argentatum Gray)

Two-year-old rubber-producing shrub, guayule (Parthenium argentatum, cv. 11591), was treated with low temperature (15°C). The leaves were harvested at regular intervals (0, 2, 4 and 6 days) and the contents of protective antioxidants (ascorbic acid, monodehydroascorbate and caroteniods) and antioxidative enzymes (superoxide dismutase, catalase, peroxidases, glutathione reductase and monodehydroascorbate reductase) were determined. Low temperature-induced significant increase in the contents of ascorbic acid, monodehydroascorbate and caroteniods as well as the activities of all antioxidative enzymes. The results show an increase in several components of the antioxidant system in cold-treated guayule plants, which may suggest a role in mitigating an increase in oxidative stress.Abbreviations: AA

Guayule ( Parthenium argentatum ) is a rubber‐producing woody shrub native to the Chihuahuan Desert of northern Mexico and Texas. Guayule produces linear, high molecular weight natural rubber that can have physical properties and applications equivalent to those of Hevea ( Hevea brasiliensis ) rubber. Guayule rubber can be extracted as a solid bulk polymer or as a latex. Guayule also is one of very few rubber‐producing plants to have ever been used commercially for rubber production. Although guayule rubber was commercially produced in the early part of the last century, more recent efforts to reinstate production have not led to commercial success because the production costs of bulk rubber were too high to permit direct competition with Hevea rubber. Guayule commercialization has been revitalized in recent years by use of the plant to produce low protein hypoallergenic latex, a higher value rubber raw material.
