Chloroplasts were once free-living cyanobacteria that became endosymbionts, but the genomes of contemporary plastids encode only ≈5–10% as many genes those their cousins, indicating either lost from or transferred to nucleus during course plant evolution. Previous estimates have suggested between 800 and perhaps 2,000 in Arabidopsis genome might come cyanobacteria, genome-wide phylogenetic surveys could provide direct this number are lacking. We compared 24,990 proteins encoded three...
The complete sequence of the 1,267,782 bp genome Wolbachia pipientis wMel, an obligate intracellular bacteria Drosophila melanogaster, has been determined. Wolbachia, which are found in a variety invertebrate species, great interest due to their diverse interactions with different hosts, range from many forms reproductive parasitism mutualistic symbioses. Analysis wMel genome, particular phylogenomic comparisons other bacteria, revealed insights into biology and evolution general. For...
All life is organized as cells. Physical compartmentation from the environment and self–organization of self–contained redox reactions are most conserved attributes living things, hence inorganic matter with such would be life's likely forebear. We propose that evolved in structured iron monosulphide precipitates a seepage site hydrothermal mound at redox, pH temperature gradient between sulphide–rich fluid iron(II)–containing waters Hadean ocean floor. The naturally arising,...
Isopentenyl diphosphate (IPP) is the central intermediate in biosynthesis of isoprenoids, most ancient and diverse class natural products. Two distinct routes IPP occur nature: mevalonate pathway recently discovered deoxyxylulose 5-phosphate (DXP) pathway. The evolutionary history enzymes involved both phylogenetic distribution their genes across genomes suggest that germane to archaebacteria, DXP eubacteria, eukaryotes have inherited for from prokaryotes. occurrence specific restricted...
Chloroplasts were once free-living cyanobacteria, mitochondria proteobacteria, and both have preserved remnants of eubacterial genomes. But from the functional standpoint, organelles retained much more their biochemistry than is reflected in DNA.
The natural transfer of DNA from mitochondria to the nucleus generates nuclear copies mitochondrial (numts) and is an ongoing evolutionary process, as genome sequences attest. In humans, five different numts cause genetic disease a dozen human loci are polymorphic for presence numts, underscoring rapid rate at which reach over time. laboratory in nature, enter via non-homolgous end joining (NHEJ) double-strand breaks (DSBs). frequency numt insertions among 85 sequenced eukaryotic genomes...
For life to have emerged from CO₂, rocks, and water on the early Earth, a sustained source of chemically transducible energy was essential. The serpentinization process is emerging as an increasingly likely that energy. Serpentinization ultramafic crust would continuously supplied hydrogen, methane, minor formate, ammonia, well calcium traces acetate, molybdenum tungsten, off-ridge alkaline hydrothermal springs interfaced with metal-rich carbonic Hadean Ocean. Silica bisulfide were also...
Lateral gene transfer is an important mechanism of natural variation among prokaryotes, but the significance its quantitative contribution to genome evolution debated. Here, we report networks that capture both vertical and lateral components evolutionary history 539,723 genes distributed across 181 sequenced prokaryotic genomes. Partitioning these by eigenspectrum analysis identifies community structure in gene-sharing networks, modules which do not correspond a strictly hierarchical...
Numerous island-inhabiting species of predominantly herbaceous angiosperm genera are woody shrubs or trees. Such "insular woodiness" is strongly manifested in the genus Echium, which continental circummediterranean distribution herbaceous, whereas endemic islands along Atlantic coast north Africa perennial shrubs. The history 37 Echium was traced with 70 kb noncoding DNA determined from both chloroplast and nuclear genomes. In all, 239 polymorphic positions 137 informative sites, addition to...
