Book excerpt: Guayule (Parthenium argentatum Gray) is a rubber producing plant native to the Chihuahuan Desert, which is currently being investigated as a source of hypoallergenic latex. Current efforts are focusing on increasing latex/rubber production in the plant by either manipulating the rubber biosynthetic pathway, altering agronomic practices to take advantage of environmental conditions that increase rubber synthesis, or both. Field and greenhouse studies were conducted to more fully understand the effect of genetic and environmental manipulation on rubber production in guayule. Three guayule breeding lines were transformed in order to increase the availability of the initiators of rubber synthesis. The tissue-culture-derived transgenic plants and their seed-generated progeny were grown in separate field experiments. Transformation with the genes for the initiators of rubber synthesis did not increase rubber concentration or yield. Height and width had high heritability estimates in the transgenic progeny and were the traits most correlated with rubber yield, while rubber concentration was poorly correlated with height and width. Greenhouse studies were conducted to understand why water stress and low night temperatures increase rubber concentration. Water stress increased the contribution of the stems to the total rubber in the plant and increased the bark to wood ratio of the stem. Most rubber is accumulated in the stems and these two effects of water stress contributed to the increased rubber concentration in water-stressed plants. Low night temperature reduced plant growth without a decrease in carbon exchange. Allocation of carbon fixation products to rubber synthesis rather than growth, contribute to the high rubber production under low night temperatures. Contributions from both breeders and agronomists are needed to further improve guayule rubber/latex yield.

Available in PDF, EPUB and Kindle. Book excerpt: This report examines the state of knowledge and the future promise of guayule Parthenium argentatum Gray, a little known shrub native to the desert of southwest Texas and northern Mexico that was a commercial source of natural rubber during the first half of this century.This perennial shrub thrives in arid conditions and can survive heavy frosts. Guayule, after thorough drying, has been found to contain as much as 26% rubber. This rubber can be used to make vehicle tires or any other item currently made with natural rubber. It is a promising plant for use in reforestation of desert fringe lands and is easy to grow. Extraction of the rubber is not technically difficult; in fact, small-scale household extraction is possible. The plant can be cut down to the ground and will grow again from the roots.The book covers: background and history, botanical information, rubber extraction, agricultural production, rubber quality, economics, research needs, selected readings and recommendations.When guayule grows actively, it produces little or no rubber. If the plant is stressed, growth slows and the products from photosynthesis are diverted into rubber production. Thus when growth slows during cold weather or because of reduced moisture supply, the rubber content begins to increase.
