Diversity of mitochondrial genome organization
Biochemistry (Moscow), 2012In this review, we discuss types of mitochondrial genome structural organization (architecture), which includes the following characteristic features: size and the shape of DNA molecule, number of encoded genes, presence of cryptogenes, and editing of primary transcripts.

The genomic and metabolic diversity of Rickettsia
Research in Microbiology, 2007Comparative genomics of Rickettsia and Orientia has revealed an exciting interplay between reductive evolutionary forces acting on metabolic genes in all species and proliferation of mobile genetic elements in some species. These contradictory evolutionary forces highlight the influence of chance, adaptation and host-cell exploitation during the ...

Microbial genomes: dealing with diversity
Current Opinion in Microbiology, 2001We have now complete genome sequences of several pairs of closely related prokaryotes (conspecific strains or congeneric species). Surprisingly, even strains of the same species can differ by as much as 20% in gene content. Conceptual and methodological approaches for dealing with such diversity are now being developed, and should transform microbial ...

Influenza genome diversity and evolution
Microbes and Infection, 2011The influenza viruses contain highly variable genomes and are able to infect a wide range of host species. Large-scale sequencing projects have collected abundant influenza sequence data for assessing influenza genome diversity and evolution. This work reviews current influenza sequence databases characteristics and statistics, as well as recent ...

An array of diverse microbial genomes
Trends in Biotechnology, 2004Methods for comparing gene frequencies across large, epidemiologically defined bacterial collections are limited. A novel microarray technology has been developed called 'library on a slide'. In this technology, hundreds of entire microbial genomes are arrayed, rather than sequences of a single genome or sets of genes.

Genome diversity in microbial eukaryotes
Trends in Ecology & Evolution, 2004The genomic peculiarities among microbial eukaryotes challenge the conventional wisdom of genome evolution. Currently, many studies and textbooks explore principles of genome evolution from a limited number of eukaryotic lineages, focusing often on only a few representative species of plants, animals and fungi. Increasing emphasis on studies of genomes

Mitochondrial genome diversity in parasites
International Journal for Parasitology, 2000Mitochondrial genomes have been sequenced from a wide variety of organisms, including an increasing number of parasites. They maintain some characteristics in common across the spectrum of life-a common core of genes related to mitochondrial respiration being most prominent-but have also developed a great diversity of gene content, organisation, and ...

Evolution and diversity of fish genomes
Current Opinion in Genetics & Development, 2003The ray-finned fishes ('fishes') vary widely in genome size, morphology and adaptations. Teleosts, which comprise approximately 23600 species, constitute >99% of living fishes. The radiation of teleosts has been attributed to a genome duplication event, which is proposed to have occurred in an ancient teleost.

Genome organization and botanical diversity
The Plant CellAbstract The rich diversity of angiosperms, both the planet's dominant flora and the cornerstone of agriculture, is integrally intertwined with a distinctive evolutionary history. Here, we explore the interplay between angiosperm genome organization and botanical diversity, empowered by genomic approaches ranging from genetic linkage ...
