  1. 6. Does arbuscular mycorrhiza symbiosis increase the capacity or the efficiency of the photosynthetic apparatus in the model legume Medicago truncatula?

    University essay from Molekylär genetik

    Author : Ateeq ur Rehman; [2010]
    Keywords : Medicago truncatula; Arbuscular mycorrhiza symbiosis; Photosynthesis; Chlorophyll fluorescence; Oxygen evolution; Lhcb1 and Lhcb2 proteins content; phosphor uptake; Reproductive fitness;

    Abstract : The Arbuscular mycorrhiza (AM) is an endosymbiont of higher plant roots. Most land plants and cultivated crops are concerned to AM symbiosis. This endosymbiosis is based on the mutual exchange of nutrients between plant and fungus. Therefore, AM symbiosis leads to an increased demand for photosynthetic products. READ MORE

  3. 7. The effect of nitrogen starvation on PSI and PSII activity in pea (Pisum sativum)

    University essay from Sektionen för ekonomi och teknik (SET)

    Author : Louise Ek; [2006]
    Keywords : pisum sativum; plant nutrition; nitrogen; photosystem; PSI; PSII; photosynthes; chloroplast; thylakoid;

    Abstract : This investigation addresses how photosynthetic efficiency is affected when pea (Pisum sativum) plants are restricted to a sole nitrogen source (i.e. ammonium or nitrate). The pea plants were watered with different nutrient solutions without NO3- or NH4+ for different time-periods in order to assay for nitrogen content. READ MORE

  4. 8. A Biomimetic Manganese Model for Artificial Photosynthesis : Q-band Electron Paramagnetic Resonance Study of a Novel Mn2(II,III) Complex

    University essay from Institutionen för teknik och naturvetenskap

    Author : Jordanos Kiflemariam; [2005]
    Keywords : Photosynthesis; manganese; electron paramagnetic resonance;

    Abstract : In natural oxygen-producing photosynthesis solar energy is stored as chemical energy, in carbohydrates, fats and amino acids, using water as electron source. The large transmembrane protein complex, PSII, is the key enzyme in the light-driven reactions. READ MORE
