“…The number of resin canals and epithelial cells increases yearly and thus the amount of PI and resin in the plant [ 38 , 40 ]. Some studies about the morphological changes of the guayule shrub over time, as well as PI and resin accumulation, try to define the best harvesting time [ 41 ].…”

Natural rubber is an essential material, especially for plane and truck tyres but also for medical gloves. Asia ranks first in the production of natural rubber, of which the Hevea tree is currently the sole source. However, it is anticipated that this source alone will not be able to fulfill the growing demand. Guayule, a shrub native to northern Mexico and southern United States, may also contribute. This plant not only contains polyisoprene, but also resin, a mixture of lipids and terpenoids. This review summarizes various aspects of this plant, from the usage history, botanical description, geographical distribution and cultivation practices, down to polyisoprene and resin biosynthesis including their distribution within the plant and molecular composition. Finally, the main processes yielding dry rubber or latex are depicted, as well as the properties of the various extracts along with economic considerations. The aim is to provide a wide picture of current knowledge available about this promising crop, a good feedstock candidate for a multiple-product biorefinery.

“…Guayule is unique in its ability to grow in some of North America’s most arid lands, receiving as little as 25–38 cm of rainfall annually (Rasutis et al, 2015). In addition to having little need of water, guayule is known to have dry weights ranging from 4 to 12% in NR (Cantú et al, 1997). Unlike rubber tree, guayule does not have laticifers, but instead, synthesizes NR in the parenchyma cells in stem (Kajiura et al, 2018).…”

Guayule ( Parthenium argentatum ) is a perennial shrub in the Asteraceae family and synthesizes a high quality, hypoallergenic cis -1,4-polyisoprene (or natural rubber; NR). Despite its potential to be an alternative NR supplier, the enzymes for cis -polyisoprene biosynthesis have not been comprehensively studied in guayule. Recently, implications of the protein complex involving cis -prenyltransferases (CPTs) and CPT-Binding Proteins (CBPs) in NR biosynthesis were shown in lettuce and dandelion, but such protein complexes have yet to be examined in guayule. Here, we identified four guayule genes – three PaCPTs ( PaCPT1-3 ) and one PaCBP , whose protein products organize PaCPT/PaCBP complexes. Co-expression of both PaCBP and each of the PaCPTs could complemented the dolichol (a short cis -polyisoprene)-deficient yeast, whereas the individual expressions could not. Microsomes from the PaCPT/PaCBP -expressing yeast efficiently incorporated 14 C-isopentenyl diphosphate into dehydrodolichyl diphosphates; however, NR with high molecular weight could not be synthesized in in vitro assays. Furthermore, co-immunoprecipitation and split-ubiquitin yeast 2-hybrid assays using PaCPTs and PaCBP confirmed the formation of protein complexes. Of the three PaCPT s, guayule transcriptomics analysis indicated that the PaCPT3 is predominantly expressed in stem and induced by cold-stress, suggesting its involvement in NR biosynthesis. The comprehensive analyses of these PaCPTs and PaCBP here provide the foundational knowledge to generate a high NR-yielding guayule.

“…Nakayama (1991) further noted that although a number of reports documenting guayule rubber content had been published, few studies had followed changes in content over long time periods. Jasso Cantu ´et al (1997) monitored biomass and rubber content in three accessions, over 3 years. They found that the biomass, rubber content and rubber yield increased with time, with rubber content oscillating around 4% for the first 18 months, and then increased to around 8% after 3 years of growth.…”
