Summary: Guayule is a perennial shrub that produces high-quality hypoallergenic natural rubber, and its processing generates three output streams including high-molecular weight rubber, resin/low molecular weight rubber, and woody bagasse. Guayule resin has economic potential in various applications such as residential pesticides, paints and coatings, wood preservative coatings, amine-epoxy strippable coatings, and adhesives. Pressurized solvent extractions like supercritical CO2 extraction show promise for scale-up due to their efficiency in extraction times, energy requirements, and solvent consumption.

Summary: The guayulin content of guayule (Parthenium argentatum Gray) varies seasonally and follows specific patterns depending on the accession and organ. Irrigation increases guayulin yield but dilutes its concentration, while fertilization has no effect on guayulin production. Different hybrids and the pure accession R1040 show variations in guayulin accumulation patterns.

Summary: The potential of guayule as an alternative crop for saline, boron- and selenium-laden soils in central California was evaluated. The study found that certain guayule accessions, specifically AZ1, AZ5, and AZ6, showed better tolerance to salinity and boron levels. Additionally, salinity increased rubber and resin production in some accessions. Guayule could also be useful in phytoremediation of selenium in poor quality soils or in soils irrigated with selenium-laden drainage water.

Summary: The research found that while drought-stressed guayule plants have higher rubber content, most rubber biosynthesis related genes are down-regulated compared to well-irrigated plants, and terpene resin biosynthesis genes are unevenly affected by water stress. Additionally, drought induces expression of fructan catabolism genes and significantly suppresses fructan biosynthesis genes in guayule.

Summary: The study analyzed the profile of 16 known argentatin compounds in 27 guayule and guayule interspecific accessions and tentatively identified the structure of five unreported argentatins. All compounds were present in varying amounts in all analyzed samples. Argentatins A, B, C, G, isoargentatin A, 16-dehydroargentatin C, and quisquagenin were found in the highest proportions. Based on available standards, argentatins A and B and isoargentatins A and B were quantified in 27 accessions and the total abundance of these compounds ranged from 13.4% to 39.6% of guayule resin in stems depending on the accession.

Summary: Argentatins A-C, the major cycloartane-type triterpenoids in guayule resin, were converted into pyrimidine, thiazole, and indole analogues. The cytotoxic activities of these analogues were compared with the parent compounds against cancer cell lines and normal cells, showing enhanced activity in the pyrimidine analogues. These findings suggest the potential of triterpenoid constituents in guayule resin for anticancer drug discovery.

Summary: This study investigated the response of guayule plants to different irrigation treatments across two years in different soil types. It found that rubber and resin accumulation increased linearly over the growing seasons, but the rates of increase varied among the irrigation treatments. Guayule plants in desert environments showed higher water productivity for rubber yield, while clay soil allowed for a reduction in irrigation without significant loss in rubber yield.

Summary: In the rubber extraction process, guayule leaves are a significant biomass waste by-product that can be utilized as antioxidants or for extracting bioactive compounds. This study examines the relationship between guayule leaf morphology and the content of 35 compounds, overall phenolic content, and antioxidant activity. The researchers found that leaf morphology is related to size and shape, allowing for classification into three groups. The study also highlights the need for standardization in determining phenolic content in guayule leaves.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.

Summary: In this study, hollow and solid lignin nanoparticles were synthesized through self-assembly and their application in PVA nanocomposite films was investigated. The results showed that the presence of hollow lignin nanoparticles in the films resulted in a room-like network structure, while the solid lignin nanoparticles induced different structural changes. The inclusion of LNPs improved the mechanical properties of the films, and both types of LNPs exhibited good hydrophobicity.

Summary: This study explored the formation mechanism of agarwood induced by fungus and its potential application in high-quality and high-yielding agarwood production. The results showed that the transition layer played a critical role in the continuous accumulation of agarwood, and the parenchyma cells of the xylem rays and interxylary phloem were the main action site of fungus. The accumulation and distribution of chemical composition in different layers were also investigated. The study identified the drivers of specific compounds and provided a theoretical foundation for future agarwood production.
