Sammanfattning : The chloroplast originates from an endosymbiotic event 1.5 billion years ago, when a free living photosynthetic bacteria was engulfed by a eukaryotic host. The chloroplastic genome has through evolution lost many genes to the nuclear genome of the host. LÄS MER
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
3. The chloroplast lumen : New insights into thiol redox regulation and functions of lumenal proteins
Sammanfattning : In higher plants oxygenic photosynthesis primarily takes place in the chloroplasts of leaves. Within the chloroplasts is an intricate membrane system, the thylakoid membrane, which is the site of light harvesting and photosynthetic electron transport. LÄS MER
Sammanfattning : Chloroplast gene expression is regulated by developmental and environmental signals. It has been proposed that there is a direct coupling between electron transport in biological membranes and gene expression (J. F. Allen, 1992, Biochim. LÄS MER
5. Targeting and function of CAH1 : Characterization of a novel protein pathway to the plant cell chloroplast
Sammanfattning : The chloroplast is the organelle within a plant cell where photosynthesis takes place. This organelle originates from a cyanobacterium that was engulfed by a eukaryotic cell. LÄS MER
