Evolution of the Bacterial Genome
Annual Review of Microbiology, 1978Until recently relatively few studies have been aimed directly at the subject of evolution of the bacterial genome, no doubt for the very good reason that the means to address relevant questions have not been at hand. We hope to show that this situation is beginning to change.

Evolution of Prokaryotic Genomes
Gene, 1993Molecular genetics, which has its roots mainly in the development of microbial genetics in the middle of this century, not only greatly facilitates investigations of essential cellular functions, but also offers a means to better understand evolutionary progress. Spontaneous mutagenesis, the driving force of biological evolution, depends on a multitude

SELEX and the evolution of genomes
Current Opinion in Genetics & Development, 1997The interrupted genome structures of complex multicellular organisms have most likely changed the evolution of the regulation of metabolism and development. Wasted intron sequences make regulation of gene expression in (for example) mammals appear to be unnecessarily complicated. The recent discoveries that globular RNA molecules are very much like the

On Genome Evolution with Innovation
2006We introduce and analyse a simple probabilistic model of genome evolution. It is based on three fundamental evolutionary events: gene duplication, loss and innovation, and it is called DLI model. The focus of the paper is around the size distribution of gene families. The formulas for equilibrium gene family sizes are derived showing that they follow a

The evolution of genomic imprinting
Development, 1990ABSTRACT We explore three possible pathways for the evolution of genomic imprinting. (1) Imprinting may be advantageous in itself when imprinted and unimprinted alleles of a locus confer different phenotypes. If a segment of DNA is imprinted in the gametes of one sex but not in those of the other, it might lead to effects correlated with

The evolution of genomic anatomy
Trends in Ecology & Evolution, 1999Just as Darwin applied his theory of natural selection to understand the details of natural history, so others have applied the idea to almost every aspect of biology from morphology to medicine. Can we similarly comprehend the rapidly accumulating details of the natural history of genomes or is selection not that strong a force?

Evolution of organellar genomes
Current Opinion in Genetics & Development, 1999Accumulating molecular data, particularly complete organellar genome sequences, continue to advance our understanding of the evolution of mitochondrial and chloroplast DNAs. Although the notion of a single primary origin for each organelle has been reinforced, new models have been proposed that tie the acquisition of mitochondria more closely to the ...

Genome evolution in polyploids
Plant Molecular Biology, 2000Polyploidy is a prominent process in plants and has been significant in the evolutionary history of vertebrates and other eukaryotes. In plants, interdisciplinary approaches combining phylogenetic and molecular genetic perspectives have enhanced our awareness of the myriad genetic interactions made possible by polyploidy. Here, processes and mechanisms

Evolution of bacterial genomes
Antonie van Leeuwenhoek, 1997This review examines evolution of bacterial genomes with an emphasis on RNA based life, the transition to functional DNA and small evolving genomes (possible plasmids) that led to larger, functional bacterial genomes.
