The other is few strict meaning of conserved interactive patterns exist due to emergence or elimination of interactions in the course of evolution.
The latter became non-functional, subject in the course of evolution to gradual elimination from the genome accompanying the loss of function.
In the evolution process, a sudden unforeseen event can occur, which may drastically alter the smooth process of evolution and cause the elimination of the set of bacteria and/or disperse them to a new environment.
Elimination of rDNA loci during chromosomal evolution has been documented in, e.g., Brassicaceae and Rosaceae [ 10, 14].
In addition, the toxR mutants have attenuated virulence, suggesting that the presence of the virulent phage may have contributed to the elimination of the infection by natural evolution.
Adaptive molecular strategies of microbes implicate diverse molecular processes like horizontal acquisition of beneficial genes or genome islands, elimination of superfluous genes through reductive evolution, genetic recombination, positive selection in certain genes and so on [ 1- 9].
This suggests elimination of ancestral TE families during tetrapod evolution.
show the signs of reductive evolution through the elimination of superfluous genes, thereby limiting their carbohydrate metabolic capacities and amino acid biosynthesis potential.
However, saddling this, already "overloaded", early period with nearly all of the more subtle diversification and leaving mostly elimination for the rest of prokaryotic evolution does not seem to provide for a plausible picture of evolution.
Development of different photoprotective mechanisms in the course of evolution of land plants has gradually made the function of flavodiiron proteins dispensable and eventually resulted in elimination of respective genes from the genomes of higher plants.
