MOBILE GENETIC ELEMENTS: THE AGENTS OF OPEN SOURCE EVOLUTION
Although MGEs are the main agents of horizontal gene transfer (HGT), relatively few have been sequenced and analysis of their genomic and phylogenetic properties lags behind that of organismal chromosomes. Specifically, the major databases do not curate plasmid and phage nucleic acid or protein sequences. Sequencing MGE genomes presents unique challenges because phages require suitable hosts for propagation and plasmids must be physically separated from each other and from the host chromosomal DNA. The relatively small size of MGEs (5−500 kb) and their varied GC content thwart current automated annotation algorithms."
