1. Effects of bagging or the combination of umbrella and bag treatments on anthocyanin accumulation in the berry skin of ‘Kyoho’ (Vitis labruscana) Grape
Abstract The object of this study was to investigate the influence of bagging or the combination of umbrella and bags on berry composition, especially anthocyanin accumulation, in ‘Kyoho’ (V. labruscana) berry skins. Five different colors and bag materials commonly used in production were chosen for this study: white, green, yellow, nonwoven and transpar

3. Quality and antioxidant potential of ‘BRS Magna’ grapes harvested in the first half of the year under different training systems and rootstocks in a tropical region
RESUMO O Submédio do Vale do São Francisco é reconhecido pela particularidade das condições de produção de uvas para diferentes usos. A produção de uvas para suco nesta região é relativamente recente. Por isso, o conhecimento acerca dos componentes do sistema produtivo ainda é limitado. O objetivo deste trabalho foi caracterizar a qualidade e a a

4. Characterization of blueberry fruits (Vaccinium spp.) and derived products
The objectives of this study were to physicochemically characterize and determine the antioxidant activities and anthocyanin contents of organic Rabbiteye blueberries grown in Southern Brazil and its derived products, in order to investigate the utility of food processing wastes as raw materials for developing products with beneficial health properties.

5. Analysis of the interactions between phytochrome and plant hormones in plant development / Estudo da interação entre fitocromo e hormônios vegetais no controle do desenvolvimento
Muitas respostas moduladas pela luz durante o desenvolvimento das plantas também são reguladas por hormônios vegetais, levando à hipótese da interação entre ambos os fatores. Uma ferramenta valiosa para testar tal interação seria o uso de mutantes fotomorfogenéticos e hormonais, bem como duplos mutantes combinando ambos. Em tomateiro, embora sejam

6. Potencial of macrophytes to remove arsenic and atrazine from water solution / Potencial de macrófitas para remoção de arsênio e atrazine em solução aquosa
The potential of three aquatic plants: Azolla caroliniana, Salvinia minima and Lemna gibba was evaluated, in this study, in order to select plants to be used in phytoremediation of water polluted by arsenic (As) and atrazine. The experiments were carried out in a green house, during six days, using vases containing Hoagland solution ( of ionic force), in the

7. Members of the c1/pl1 Regulatory Gene Family Mediate the Response of Maize Aleurone and Mesocotyl to Different Light Qualities and Cytokinins1
We investigated the role of transcription factors (R, SN, C1, and PL) in the regulation of anthocyanin biosynthesis by different light qualities (white, red, blue, and ultraviolet) and by cytokinin in maize (Zea mays). We analyzed anthocyanin accumulation, structural gene expression, and regulatory gene expression in the seed aleurone and the seedling mesoco

8. Reduction of Light-Induced Anthocyanin Accumulation in Inoculated Sorghum Mesocotyls1 : Implications for a Compensatory Role in the Defense Response
Sorghum (Sorghum bicolor L. Moench) accumulates the anthocyanin cyanidin 3-dimalonyl glucoside in etiolated mesocotyls in response to light. Inoculation with the nonpathogenic fungus Cochliobolus heterostrophus drastically reduced the light-induced accumulation of anthocyanin by repressing the transcription of the anthocyanin biosynthesis genes encodin

9. ANTHOCYANINLESS2, a homeobox gene affecting anthocyanin distribution and root development in Arabidopsis.
The ANTHOCYANINLESS2 (ANL2) gene was isolated from Arabidopsis by using the maize Enhancer-Inhibitor transposon tagging system. Sequencing of the ANL2 gene showed that it encodes a homeodomain protein belonging to the HD-GLABRA2 group. As we report here, this homeobox gene is involved in the accumulation of anthocyanin and in root development. Histological o

10. Photosynthetic Independence of Light-induced Anthocyanin Formation in Zea Seedlings 1
Results are reported which support the view that the photosynthetic photosystems are not involved in the high irradiance response (HIR) phenomenon of light-dependent anthocyanin biosynthesis in dark-grown Zea mays L. seedlings. A negative correlation between change in greening rates and change in light-dependent anthocyanin accumulation rates with age was de

11. Sugar-Dependent Gibberellin-Induced Chalcone Synthase Gene Expression in Petunia Corollas.
The induction of anthocyanin synthesis and anthocyanin biosynthetic gene expression in detached petunia (Petunia hybrida) corollas by gibberellic acid (GA3) requires sucrose. Neither sucrose nor GA3 alone can induce these processes. We found that GA3 enhances sucrose uptake by 20 to 30%, and we tested whether this is the mechanism by which the hormone induce

12. Changes in Anthocyanin and Phenolics Content of Grapevine Leaf and Fruit Tissues Treated with Sucrose, Nitrate, and Abscisic Acid 1
Sucrose (0.04 to 0.12 m) induces accumulation of both total phenolics and anthocyanin in leaf discs of grapevine (Vitis vinifera L.) incubated in intermittent light. Abscisic acid (20 μM) and 2-chloroethyl phosphonic acid (60 μm) act synergistically with the sucrose to enhance its induction of both total phenolics and anthocyanin. The magnitude of this int
