Quality assurance is a major issue in the food industry. The authenticity of food ingredients and their traceability are required by consumers and authorities. Plant species such as barley (Hordeum vulgare), rice (Oryza sativa), sunflower (Helianthus annus), wheat (Triticum aestivum) and maize (Zea mays) are very common objects of interest of genetic modification (GMO); therefore the developmen...

The Brazilian biodiversity offers a multiplicity of raw materials with great potential in cosmetics industry applications. Some vegetable oils and fatty esters increase skin hydration by occlusivity, keeping the skin hydrated and with a shiny appearance. Sunflower (Helianthus annus L.) oil is widely employed in cosmetic emulsions in the form of soaps, creams, moisturizers and skin cleansers due...

The coccinellid predator Coleomegilla maculata (DeGeer) is found throughout the central and eastern United States and is a potential biological control agent for interiorscapes. Currently, the systemic insecticide imidacloprid is widely used in interiorscape and landscape integrated pest management. Effects of imidacloprid on the Þtness and behavior of C. maculata were examined by conÞning grou...

Experiments were conducted to examine the utility of a spectrophometric leaf disc assay for detecting shikimate accumulation after glyphosate application in sunflower, proso millet, and wheat. The assay was conducted on both greenhouseand field-grown plants. Glyphosate was applied at five rates ranging from 840 to 53 g ae ha. Shikimate accumulation data were generated at 1, 4, 7, and 14 d after...

Recent studies have suggested that domestication was a slower evolutionary process than was previously thought. We address this issue by quantifying rates of phenotypic change in crops undergoing domestication, including five crops from the Near East (Triticum monococcum, T. dicoccum, Hordeum vulgare, Pisum sativum, Lens culinaris) and six crops from other regions (Oryza sativa, Pennisetum glau...
