Organelle transcriptomes: products of a deconstructed genome.
Genetic drift and mutational pressure have shaped the evolution of mitochondrial and chloroplast genomes, giving rise to mechanisms that regulate their gene expression, which often differ from those in their prokaryotic ancestors. Advances in next generation sequencing technologies have enabled highly detailed characterization of organelle transcriptomes and the discovery of new transcripts and...
متن کاملOrganelle biogenesis and positioning in plants.
The biogenesis and positioning of organelles involves complex interacting processes and precise control. Progress in our understanding is being made rapidly as advances in analysing the nuclear and organellar genome and proteome combine with developments in live-cell microscopy and manipulation at the subcellular level. This paper introduces the collected papers resulting from Organelle Biogene...
متن کاملGenome-Wide Survey of Ds Exonization to Enrich Transcriptomes and Proteomes in Plants
Insertion of transposable elements (TEs) into introns can lead to their activation as alternatively spliced cassette exons, an event called exonization which can enrich the complexity of transcriptomes and proteomes. Previously, we performed the first experimental assessment of TE exonization by inserting a Ds element into each intron of the rice epsps gene. Exonization of Ds in plants was bias...
متن کاملA conserved transcription factor mediates nuclear control of organelle biogenesis in anciently diverged land plants.
Land plant chloroplasts evolved from those found in the green algae. During land plant evolution, nuclear regulatory mechanisms have been modified to produce morphologically and functionally diverse chloroplasts in distinct developmental contexts. At least some of these mechanisms evolved independently in different plant lineages. In angiosperms, GOLDEN2-LIKE (GLK) transcription factors regulat...
متن کاملGeneration and evolutionary fate of insertions of organelle DNA in the nuclear genomes of flowering plants.
Nuclear genomes are exposed to a continuous influx of DNA from mitochondria and plastids. We have characterized the structure of approximately 750 kb of organelle DNA, distributed among 13 loci, in the nuclear genomes of Arabidopsis and rice. These segments are large and migrated to the nucleus quite recently, allowing us to reconstruct their evolution. Two general types of nuclear insertions c...
