متن کاملIdentification and categorization of horizontally transferred genes in prokaryotic genomes.
Horizontal gene transfer (HGT), a process through which genomes acquire genetic materials from distantly related organisms, is believed to be one of the major forces in prokaryotic genome evolution. However, systematic investigation is still scarce to clarify two basic issues about HGT: (1) what types of genes are transferred; and (2) what influence HGT events over the organization and evolutio...
متن کاملMathematical modeling of evolution of horizontally transferred genes.
We describe a stochastic birth-and-death model of evolution of horizontally transferred genes in microbial populations. The model is a generalization of the stochastic model described by Berg and Kurland and includes five parameters: the rate of mutational inactivation, selection coefficient, invasion rate (i.e., rate of arrival of a novel sequence from outside of the recipient population), wit...
متن کاملHGTree: database of horizontally transferred genes determined by tree reconciliation
The HGTree database provides putative genome-wide horizontal gene transfer (HGT) information for 2472 completely sequenced prokaryotic genomes. This task is accomplished by reconstructing approximate maximum likelihood phylogenetic trees for each orthologous gene and corresponding 16S rRNA reference species sets and then reconciling the two trees under parsimony framework. The tree reconciliati...
متن کاملRegulatory integration of horizontally-transferred genes in bacteria.
Horizontal transfer of genetic material is a fact of microbial life and bacteria can obtain new DNA sequences through the processes of conjugation, transduction and transformation. This offers the bacterium the possibility of evolving rapidly by importing new genes that code for new traits that may assist in environmental adaptation. Research in this area has focused in particular on the role o...
