Phage evolution: New worlds of genomic diversity

Phage evolution: New worlds of genomic diversity

A recent comparative survey of genomes of phages infecting mycobacteria reveals a vast combinatorial network of gene rearrangements and may provide general models for pattern and process in genome evolution.

Genomic Diversity and Evolution of the Lyssaviruses

Lyssaviruses are RNA viruses with single-strand, negative-sense genomes responsible for rabies-like diseases in mammals. To date, genomic and evolutionary studies have most often utilized partial genome sequences, particularly of the nucleoprotein and glycoprotein genes, with little consideration of genome-scale evolution. Herein, we report the first genomic and evolutionary analysis using comp...

Genomic Evolution and Diversity in Artiodactyla

Evolution: To seek out new worlds

A recent study of stickleback 'ecomorphs' generated by independent speciation events in different freshwater lakes suggests that, despite historical contingency, natural selection can run in surprisingly similar ways on multiple occasions.

Genomic Diversity and Evolution of the Fish Pathogen Flavobacterium psychrophilum

Flavobacterium psychrophilum, the etiological agent of rainbow trout fry syndrome and bacterial cold-water disease in salmonid fish, is currently one of the main bacterial pathogens hampering the productivity of salmonid farming worldwide. In this study, the genomic diversity of the F. psychrophilum species is analyzed using a set of 41 genomes, including 30 newly sequenced isolates. These were...
