The yeast Saccharomyces cerevisiae was the ®rst organism from which a chromosome was sequenced and the ®rst eukaryote to have its genome completely sequenced. As I write, the genome sequence of the ®ssion yeast Schizosaccharomyces pombe is being completed and this will probably be just the fourth complete eukaryotic genome sequence. Yeast (the journal) has played an important role in both the s...
Bacterial and archaeal complete genome sequences have been obtained from a wide range of evolutionary lines, which allows some general conclusions about the phylogenetic distribution and evolution of bioenergetic pathways to be drawn. In particular, I searched in the complete genomes for key enzymes involved in aerobic and anaerobic respiratory pathways and in photosynthesis, and mapped them in...
Recent transcriptome and genome projects have dramatically expanded the biological data available across the phylum Nematoda. Here we summarize analyses of these sequences, which have revealed multiple unexpected results. Despite a uniform body plan, nematodes are more diverse at the molecular level than was previously recognized, with many species- and group-specific novel genes. In the genus ...
Until recently, the apicomplexan parasites, Cryptosporidium hominis and C. parvum, were considered the same species. However, the two parasites, now considered distinct species, exhibit significant differences in host range, infectivity, and pathogenicity, and their sequenced genomes exhibit only 95-97% identity. The availability of the complete genome sequences of these organisms provides the ...
Motivation: Orthopoxviruses are a large group of closely related viruses displaying a high homology of their genomic nucleotide sequences. These viruses differ also in the severities of the diseases they cause and have different host ranges. Evolutionary relationships of various orthopoxvirus species are yet vague (Marennikova, Shchelkunov, 1998). Results: Analysis of the structures of importan...
The 2014 Ebola outbreak in West Africa is the largest documented for this virus. To examine the dynamics of this genome, we compare more than 100 currently available ebolavirus genomes to each other and to other viral genomes. Based on oligomer frequency analysis, the family Filoviridae forms a distinct group from all other sequenced viral genomes. All filovirus genomes sequenced to date encode...
At the end of January I travelled to the States to speak at and attend the first O’Reilly Bioinformatics Technology Conference [14]. It was a large, well-organized and diverse meeting with an interesting history. Although the meeting was not a typical academic conference, its style will, I am sure, become more typical of meetings in both biological and computational sciences. Speakers at the ev...
Microsporidia have been known for some time to possess among the smallest genomes of any eukaryote. There is now a completely sequenced microsporidian genome, as well as several other large-scale sequencing efforts, so the nature of these genomes is becoming apparent. This paper reviews some of the characteristics of microsporidian genomes in general, and some of the recent discoveries made thr...
