1. 1. The light-harvesting antenna of higher plant photosystem I

   Författare :Ulrika Ganeteg; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; antisense; Arabidopsis thaliana; chlorophyll; fitness; LHC; photosynthesis; Växtfysiologi; Plant physiology; Växtfysiologi;

   Sammanfattning : During photosynthesis, two multi-protein complexes, photosystems (PS) I and II work in tandem to convert the light-energy absorbed by the light-harvesting antennae into chemical energy, which is subsequently used to assimilate atmospheric carbon dioxide into organic carbon compounds. This is the main nutritional basis for life on Earth. LÄS MER

3. 2. Dissecting the photosystem II light-harvesting antenna

   Författare :Jenny Andersson; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; antisense; Arabidopsis thaliana; chlorophyll; carotenoid; feedback de-excitation; fitness; LHC; NPQ; photosynthesis; state transitions; xanthophyll; Växtfysiologi; Plant physiology; Växtfysiologi; Physiological Botany; fysiologisk botanik;

   Sammanfattning : In photosynthesis, sunlight is converted into chemical energy that is stored mainly as carbohydrates and supplies basically all life on Earth with energy.In order to efficiently absorb the light energy, plants have developed the outer light harvesting antenna, which is composed of ten different protein subunits (LHC) that bind chlorophyll a and b as well as different carotenoids.

4. 3. Functions of REP27 and the low molecular weight proteins PsbX and PsbW in repair and assembly of photosystem II

   Författare :Jose Gines Garcia Cerdan; Wolfgang Schröder; Eva-Mari Aro; Umeå universitet; []
   Nyckelord :Photosynthesis; photosystem II reaction center; PSII-LHCII supercomplex; antisense plant; T-DNA knockout plant; auxiliary protein; Biochemistry; biokemi;

   Sammanfattning :     Oxygenic photosynthesis is the major producer of both oxygen and organic compounds on earth and takes place in plants, green algae and cyanobacteria. The thylakoid membranes are the site of the photosynthetic light reactions that involve the concerted action of four major protein complexes known as photosystem II (PSII), cytochrome b6f complex, ATP synthase and photosystem I (PSI).

5. 4. Signalling between plants and microorganisms

   Författare :Ulrika Troedsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; symbiosis; Chitinase; rhizobium; mycorrhiza; plant; glucanase; Biology; Biologi;

   Sammanfattning : Plants and microbes can interact in several ways. Plants can be attacked by different types of pathogens like fungi, virus and bacteria, but can also form symbioses with fungi and bacteria. Certain common antimicrobial proteins are produced by the plants regardless of the type of microbial interaction with the plant. LÄS MER

7. 5. Development of Transgenic Potatoes to Attain Novel Starch Qualities

   Författare :Mariette Andersson; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Livsmedelsteknik; Food and drink technology; Biokemisk teknik; Biochemical technology; StGH; starch yield; RNAi; antisense; gene silencing; ahas; potato transformation; sbe2; sbe1; gbss; amylopectin; amylose; Starch; potato;

   Sammanfattning : Starch is a plant-derived polysaccharide with many uses in different food and non-food applications. In this thesis, the production of two novel potato starch qualities, amylopectin and high-amylose, and the modifications and the characteristics of the produced plants and starches are described.
