  1. 1. Characterisation of the Clp Proteins in Arabidopsis thaliana

    Författare :Bo Zheng; Adrian K. Clarke; Vaughan Hurry; Cecilia Sundby-Emanuelsson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Arabidopsis; molecular chaperone; protein degradation; protease; Clp Hsp100; ClpP; stress response; antisense repression; chloroplast development; Växtfysiologi; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Unlike in the greenhouse, plants need to cope with many environmental stresses under natural conditions. Among these conditions are drought, waterlogging, excessive or too little light, high or low temperatures, UV irradiation, high soil salinity, and nutrient deficiency. LÄS MER

  3. 2. Phylogenetic Support and Chloroplast Genome Evolution in Sileneae (Caryophyllaceae)

    Författare :Per Erixon; Bengt Oxelman; Sean Graham; Uppsala universitet; []
    Nyckelord :Biology; Phylogenetics; Bayesian inference; Bootstrapping; cpDNA; Sileneae; Interspecific chloroplast recombination; Hybridization; clpP; Positive selection; Extreme substitution rates; Biologi;

    Sammanfattning : Evolutionary biology is dependent on accurate phylogenies. In this thesis two branch support methods, Bayesian posterior probablities and bootstrap frequencies, were evaluated with simulated data and empirical data from the chloroplast genome. LÄS MER

  4. 3. Bacterial Activity and Community Composition in the Rhizosphere. Influence of plant species, root age, nitrogen addition and mycorrhizal status

    Författare :Katarina Söderberg; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; CLPP; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Biolog; PLFA; mycorrhizal status; nitrogen addition; along roots; plant species; root age; thymidine and leucine incorporation; bacterial composition; Rhizosphere; bacterial activity;

    Sammanfattning : Microbial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. LÄS MER

  5. 4. Structural and functional studies of the ATP-dependent Clp proteases in cyanobacteria

    Författare :Frida Ståhlberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtmolekylärbiologi; Clp Proteaser; Synechococcus elongatus;

    Sammanfattning : Proteins are essential in all living organisms and they are involved in a myriad of biological functions. It is vital for cells to have efficient surveillance and quality control systems that ensure damaged proteins are either repaired to their functional state or quickly removed by degradation. LÄS MER

  7. 5. Biochemical studies of the essential Clp protease in cyanobacteria and its associated adaptor proteins

    Författare :Anders Tryggvesson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Clp-protease; Cyanaobacteria; adaptor proteins;

    Sammanfattning : Proteins are an essential part of all organisms and are involved in many cellular processes. To regulate the function of proteins and facilitate their removal when damaged or otherwise compromised, sophisticated control systems have evolved that include molecular chaperones and proteases.
