  1. 1. Modification of flavonoid content and photosynthesis by ultraviolet-B radiation. Atrazine-tolerant and -sensitive ultivars of Brassica napus

    Författare :Louise Olsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; recovery; quercetin; photosynthesis; photoinhibition; photoacoustics; leaf anatomy; kaempferol; flavonoid; D1 protein; fluorescence; cold stress; carbon dioxide; atrazine tolerance; Brassica napus; UV-B; Physiological biophysics; Växtfysiologi;

    Sammanfattning : Levels of ultraviolet-B (UV-B, 280-320 nm) radiation reaching the Earth´s surface increase due to stratospheric ozone depletion. In this thesis the effect of enhanced UV-B radiation was studied on the atrazine-tolerant mutant Stallion, susceptible to photoinhibition, and the atrazine-sensitive cultivar Paroll of Brassica napus (oilseed rape).

    Sammanfattning : The total antioxidant capacity was measured and the major phenolic and flavonoid compounds were identified and quantified in a selection of Bolivian crops growing at different altitudes above seal level (a.s.l.). LÄS MER

  4. 3. Metabolic engineering of S. cerevisiae for the production of flavonoids

    Författare :Marta Tous Mohedano; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; microbial cell factories; high-value products; sustainability; cinnamic acid; plant natural products; Genetic engineering; yeast;

    Sammanfattning : The interest in the production of natural products such as flavonoids has been increasing during the last decade. Flavonoids have several attractive bioactivities including antitumoral, antioxidant or antimicrobial properties. To produce these high-value products, we usually recur to chemical synthesis or plant extraction. LÄS MER
