Introduction Sunflower (Helianthus annus) seeds and byproduct meals are of importance in some parts of the world because they provide a source of high-oil protein material for livestock diets. The major sunflower producing areas of the world today are Argentina, China, Eastern Europe, and the United States. Although Australia produces only relatively small amounts of sunflower meal (Table 1), i...

Direct sequencing of cytochrome oxidase subunit III (coxIII) mRNA with a specific primer confirms RNA editing in sunflower (Helianthus annus) mitochondria. Six instances of mRNA editing could be verified, one of these specific to this species. All the editing events involve C to U transitions in the coxIII mRNA causing codon changes that lead to amino acids better conserved in evolution than th...

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...

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...
