  1. 1. Get in tune : chloroplast and nucleus harmony

    Författare :Dmitry Kremnev; Åsa Strand; Francis-Andre Wollman; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; development; gene expression;

    Sammanfattning : Photosynthetic eukaryots emerged as a result of several billion years of evolution between proeukaryotic cell and ancestral cyanobacteria that formed modern chloroplasts. The symbiotic relationship led to significant rearrangements in the genomes of the plastid and the nucleus: as many as 90 % of all the plastid genes were transferred to the nucleus. LÄS MER

  2. 2. Regulation of chloroplast development during the greening process

    Författare :Yan Ji; Åsa Strand; Eevi Rintamäki; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; light response; anterograde signalling; plastid transcription; chloroplast development; photosynthesis; bZIP; PEP complex; de-etiolation; molekylärbiologi; Molecular Biology;

    Sammanfattning : Upon light exposure, the expression of one-third of the nuclear-encoded genes is changing, including genes encoding many chloroplast-targeted proteins responsible for the initiation of plastid transcription and the establishment of photosynthesis. The control of the nuclear-encoded genes involved in the development of chloroplast is referred to as anterograde signalling. LÄS MER

  3. 3. Vesicle transport in chloroplasts with emphasis on Rab proteins

    Författare :Mohamed Alezzawi; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :chloroplast; vesicle; transport; Arabidopsis; Rab; lipid; clathrin; protein; COPI; COPII;

    Sammanfattning : Chloroplasts perform photosynthesis using PSI and PSII during its light-dependent phase. Inside the chloroplast there is a membrane called thylakoid. The thylakoid membranes are an internal system of interconnected membranes that carry out the light reactions of photosynthesis. LÄS MER

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

    Författare :Bo Zheng; Adrian K. Clarke; Vaughan Hurry; Cecilia Sundby-Emanuelsson; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

  5. 5. Steady, ready, go - proteomics of etioplast inner membranes reveals a high readiness for light

    Författare :Lisa A. Blomqvist; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :chloroplast; etioplast; NADPH:protochlorophyllide oxidoreductase; prolamellar body; proteomics; prothylakoid; transmembrane; Triticum aestivum; wheat;

    Sammanfattning : 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 illuminat... LÄS MER
