This approach has been used effectively to assign provisional functional annotations to protein coding genes identified by genome sequencing [ 42- 44], to measure the effects of functional genomic variables on protein evolution rates [ 45- 47], and applied to other areas of evolutionary genomics [ 48], thereby increasing our understanding of eukaryotic evolution [ 49, 50].
In the latter study, it was proposed that poxvirus genomic evolution takes place under heterogeneous rates of gene gain and loss along distinct lineages, whereas a core set of 34 genes defines the functional or metabolic identity of the virus family.
Infection can persist over many years, during which genomic evolution is driven by high rates of mutation and recombination.
For instance, how does the rate of genomic evolution in a given E. coli lineage by mutation compare to that by horizontal gene transfer (Guttman and Dykhuizen, 1994; Dolbrindt et al., 2010; Paul et al., 2013)?
Demonstration that adoption of a parasitic lifestyle influences the rate of genomic evolution is relevant to attempts to infer molecular phylogenies of parasitic plants and to estimate their evolutionary divergence times using sequence data.
Rather than observing a gradual progression of genetic changes in tumor cell populations, no intermediate genotypes were found between the different populations, and in fact the authors noted the 'rate of effective population growth markedly exceeds [the] rate of genomic evolution' [ 99].
The study also furnishes new information concerning rates of murine genomic evolution and features of DNA mutagenesis (at the time of SNP formation) that should be viewed as "adaptive".
pisum genome [24] will help further advance comparative aphid research, but more representative aphid species are needed to fully understand genomic evolution in this large insect family, particularly in regards to gene duplication and molecular evolution rates [24], [27].
These studies also demonstrate significant genomic evolution, including formation of polyploid nuclei within a single sample, suggesting a very high rate of genomic instability.
The genomic evolution of tRNA gene thus may be linked to the evolution of genome organization.
