16. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways
Sammanfattning : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. LÄS MER
17. Haustoria regulation in the facultative parasitic plant Phtheirospermum japonicum
Sammanfattning : Parasitic plants are important agricultural pests that lead to considerable yield losses annually. Parasitic plants that completely rely on their hosts for their survival are known as obligatory parasites, whereas those independent of their hosts but parasitize under the right conditions are known as facultative parasitic plants.

18. The Plant Plasma Memrbane H+-ATPase: regulation by phosphorylation and 14-3-3 proteins
Sammanfattning : The plant plasma membrane H+-ATPase is a predominant membrane enzyme that provides the energy for secondary active transport across the plasma membrane. Consequently, the H+-ATPase is thought to play a major role in many cell processes, and it is implicated to be regulated by a number of factors, including hormones, blue light, and fungal toxins The plant plasma membrane H+-ATPase is regulated via an autoinhibitory domain located within the C-terminal region of the enzyme.

19. Production and engineering of a xyloglucan endo-transglycosylase from Populus tremula x tremuloides
Sammanfattning : The aim of this work was to develop a production process for the enzyme xyloglucan endo-transglycosylase from Populus tremula x tremuloides (PttXET16-34). The natural transglycosylating activity of this enzyme has previously been employed in a XET-Technology. LÄS MER
20. The role of regeneration in plant niche differentiation and habitat specialization
Sammanfattning : To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. LÄS MER
