Characterization of cholorplast protein import in Arabidopsis thaliana with emphasis on Toc64 and Tic55
(2009-12-15)
Although the chloroplast possesses a genome of its own most genes have been transferred during the evolution to the nucleus to acquire more transcriptional control, and couple the activities of the whole cell to events at ...
Steady, ready, go - proteomics of etioplast inner membranes reveals a high readiness for light
(2009-05-25)
Light is essential for development of photosynthetically active chloroplasts. In the absence of light proplastids develop into etioplasts which are readily transformed into chloroplasts upon illumination. The etioplast ...
An evolutionary view of the taxonomy and ecology of Inocybe (Agaricales) with new perspectives gleaned from GenBank metadata
(2009-04-16)
Inocybe (Inocybaceae) is one of the most speciose genera among the gilled mushrooms (Agaricales) but large parts of its taxonomy and evolutionary history remain poorly explored. The present thesis shows that the traditional ...
On Toxicant-Induced Succession in Periphyton Communities: Effects of Single Chemicals and Chemical Mixtures
(2009-02-27)
This thesis deals with the effects of single chemicals and chemical mixtures on biological communities. Ecosystems are exposed to complex mixtures of chemicals, and because combination effects can occur, it is necessary ...
Carbon stock and fluxes in Nyungwe forest and Ruhande Arboretum in Rwanda
(2009-11-20)
Conservation and sequestration of carbon in forest ecosystems are potential strategies to reduce or stabilize the atmospheric greenhouse gas concentrations and mitigate climate change. Estimating the degree to which forest ...
Interplay between phospholipids and digalactosyldiacylglycerol in phosphate limited oats
(2009-03-09)
Phosphate is an essential nutrient. In most soils it is limiting, which has resulted
in that phosphate is supplied as fertilizer to increase crop yield. Through
evolution, plants have adapted several mechanisms to increase ...
Greenhouse gas fluxes between drained forested peatlands and the atmosphere - influence of nutrient status and wood ash fertilization
(2009-04-24)
The management of peatlands for wood production involves drainage and, sometimes, fertilization with, for example, wood ash. The effects of these measures on greenhouse gas fluxes, in relation to the nutrient status of the ...
