Summary: Rosin and coconut oil have significant adjuvant effects on herbicides, reducing dosage and improving weed control efficiency in both lab and field trials. They decrease the contact angle and surface tension, while increasing spreading diameter and maximum retention of herbicides, showing potential for natural adjuvants in weed control formulations.

Summary: A glossy mutant lacking an epicuticular wax layer was identified in the ?-irradiated M2 mutant population of the onion cultivar Bhima Super. The mutant displayed poor accumulation of wax crystals, primarily near the stomata. Gene expression analysis revealed downregulation of wax biosynthesis genes in the glossy mutant. These findings contribute to our understanding of wax biosynthesis in onions and provide a foundation for utilizing the glossy mutant trait for breeding programs.

Summary: Berries of the genus Vaccinium found in bogs and forests of Northern Europe are a valuable source of biologically active substances containing sterols, unsaturated fatty acids, flavonoids, and anthocyanins, which provide various health benefits such as treating urinary tract inflammation, controlling blood sugar levels, improving cardiovascular health, and reducing oxidative stress caused by free radicals. Studies have shown that lipid fractions of bilberry and lingonberry contain fatty acids, sterols, isoprenoids, and long-chain aliphatic compounds, and that fractions with high concentrations of phenolic acids have potential UV-B blocking activity, while those with high sterol content effectively inhibit bacterial growth. These findings are important for the development of natural functional ingredients for nutraceuticals and cosmeceuticals.

Summary: Cuticular waxes form a hydrophobic barrier on terrestrial plants, protecting them from environmental stresses like drought. The ZxABCG11 gene from the xerophyte Zygophyllum xanthoxylum was found to enhance cuticular wax accumulation and increase drought tolerance when introduced into Arabidopsis thaliana. This suggests a potential mechanism for improving plant resilience to water scarcity through genetic manipulation.

Summary: This study evaluated the effects of spraying chlorantraniliprole and difenoconazole with plant oil adjuvant on uptake, translocation, and terminal residue in rice. The adjuvant destroyed the cuticular wax of rice leaf, facilitating pesticide penetration. It promoted the translocation of difenoconazole from leaves to stems and inhibited chlorantraniliprole translocation. Although the adjuvant increased initial deposition, it did not significantly affect terminal residue. The findings promote the safe use of these pesticides in rice production, especially with plant oil adjuvants. Further studies on different rice cultivars are needed for generalization.

Summary: Combining ultraviolet light and chlorine can enhance the degradation of perfluorooctanoic acid (PFOA), a type of per- and polyfluoroalkyl substance (PFAS). This method not only increases the removal rate of PFOA, but also generates a significant amount of fluoride. Radical scavenger tests confirmed the important role of Cl· and Cl-2(·) in the degradation process.

Summary: Even C22-32 aliphatic aldehydes were synthesized and analyzed, revealing their crystalline structures and solid-solid transitions into the R phase. Binary mixtures of triacontanal and nnonacosane, constituents of plant cuticular waxes, were found to be partially miscible and also possess R-type phases. Mutations in the expression of aldehydes in cuticular waxes can lead to glabrous plants with decreased cuticular permeability and drought intolerance. Aldehydes may play a role as miscibility intermediaries and their R phases may be important for wax crystal growth in plants.

Summary: Brassica carinata is a renewable biofuel crop with high oil and polyunsaturated fatty acids contents. This study explores the variations in cuticular wax content and composition in B. carinata, revealing a wide range of wax content and various classes of wax. The study also suggests that modifying specific wax content can increase the overall wax content and enhance the composition of the cuticle. This research provides valuable insight into wax biosynthetic pathways and the development of drought-tolerant cultivars of B. carinata.

Summary: The cuticular transpiration rate and wax composition of lily cultivars varied between cultivars and organs, indicating that different wax coverage may affect the shelf life of cut flowers. The main wax constituents were very-long-chain aliphatics dominated by n-alkanes, with differences in chain-length distributions between organs.

Summary: Comparing the morphology, chemical composition, and gene expression of cuticular waxes between a wax-deficient mutant and wild type fruit, it was found that differences in wax composition may contribute to postharvest weight loss and decay rates. The study suggests that wax-related genes may regulate the morphology and chemical composition of cuticular waxes, playing a critical role in postharvest quality of navel oranges.
