Assessment of phylogenetic structure in genome size--gene content correlations.
Gene content and gene-coding percentage can be predicted from genome size in newly sequenced organisms. Here, we investigate whether these predictions are influenced by phylogenetic relationships between the involved species. Combining a highly resolved phylogenetic tree with a large compilation of gene content data, our results reveal the presence of significant phylogenetic structure in the c...
متن کاملGenome structure and gene content in protist mitochondrial DNAs.
Although the collection of completely sequenced mitochondrial genomes is expanding rapidly, only recently has a phylogenetically broad representation of mtDNA sequences from protists (mostly unicellular eukaryotes) become available. This review surveys the 23 complete protist mtDNA sequences that have been determined to date, commenting on such aspects as mitochondrial genome structure, gene co...
متن کاملStrong phylogenetic inertia on genome size and transposable element content among 26 species of flies
While the evolutionary mechanisms driving eukaryote genome size evolution are still debated, repeated element content appears to be crucial. Here, we reconstructed the phylogeny and identified repeats in the genome of 26 Drosophila exhibiting a twofold variation in genome size. The content in transposable elements (TEs) is highly correlated to genome size evolution among these closely related s...
متن کاملthe role of thematic structure in comprehending spoken language
in fact this study is concerned with the relationship between the variation in thematice structure and the comprehension of spoken language. so the study focused on the following questions: 1. is there any relationship between thematic structure and the comprehension of spoken language? 2. which of the themes would have greated thematic force and be easier for the subjects to comprehend? accord...
