We report the cloning and functional characterization of the first heat-shock transcription factor that is specifically expressed during embryogenesis in the absence of environmental stress. In sunflower embryos this factor, HaHSFA9, trans-activated promoters with poor consensus heat-shock cis-elements, including that of the seed-specific Hahsp17.6G1 gene. Mutations that improved the heat-shock...

IVANOVA, P., V. CHALOVA, L. KOLEVA, I. PISHTIYSKI and M. PERIFANOVA – NEMSKA, 2012. Optimization of protein extraction from sunflower meal produced in Bulgaria. Bulg. J. Agric. Sci., 18: 153-160 Sunflower meal obtained after defatting of sunflower seeds is a by-product, which has the potential to serve as an attractive source for the preparation of protein isolates for food purposes. Protein ex...

Enhanced Cd concentrations in wheat (Triticum aestivum L.) grain produced on saline soils of central Iran have been recently reported. Because wheat bread is a major dietary component for the Iranian people, practical approaches to decrease Cd concentration in wheat grain were investigated. This study investigated the influence of sunflower-wheat vs. cotton-wheat rotations on extractable Cd and...

Lentz et al. (1) propose that, along with being domesticated in eastern North America (ENA) by 2800 B.C. (2, 3), the sunflower was independently domesticated and widely cultivated in pre-Columbian Mesoamerica. Archaeological evidence presented, however, falls far short of an adequate supporting argument for their claim. Pre-Columbian contexts in ENA have yielded 3,000 domesticated sunflower ach...

BACKGROUND: The active oxygen species, despite the damaging effects they have useful roles in the body are living things. OBJECTIVES: This research was done to determine whether Reactive Oxygen Species (ROS) could mediate Cyanide and Methylviologen signal in seed dormancy alleviation and sunflower seed germination, more widely, to assess their putative ro...

This study aimed to investigate the effect of sunflower seeds, either as whole or as oil, on rumen fermentation, milk production, milk composition and fatty acids profile in dairy goats. Fifteen lactating Damascus goats were divided randomly into three groups (n = 5) fed a basal diet of concentrate feed mixture and fresh Trifolium alexandrinum at 50:50 on dry matter basis (Control) in addition ...

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...

Total proteins, esterases and acid phosphatases from pollen, seeds and leaves of three sunflower cultivars were separated by 2-D electrophoresis. The characteristic peptides for each cultivar were identified. The seeds and pollen of the cultivar Wielkopolski contained 45 and 37 characteristic peptides, respectively, while the seeds and pollen of Coril contained 73 and 35 characteristic peptides...
