While lateral gene transfer from a trematode worm could ultimately benefit the lake sturgeon, evidence of the Trichomonas pathogen is more likely to have a negative effect.
According to them, the genes tRNA synthetase, ATPase, and carbomyl phosphate synthetase could not be used confidently to root the tree of life because of the difficulty to choose between different evolutionary scenarios, knowing that gene duplication, gene loss, and lateral gene transfer have been frequent during prokaryotic evolution.
This lateral gene transfer would not have occurred recently, because the Fe-hydrogenases of entamoebas and giardias showed only a 40% amino acid identity with each other, and each fe-hydrogenase gene has the codon usage of its host.
Therefore, the virophage could be a vehicle mediating lateral gene transfer between giant viruses.
It does not predict gene content in the remaining 99% of the genome, because of the role of lateral gene transfer (LGT) in generating diversity within and between prokaryotic groups.
Phylogeographic reconstruction of a bacterial species with high levels of lateral gene transfer.
It's an interesting case of Lateral Gene Transfer, or the movement of genes between distantly related species," said Patrick Keeling, a University of British Columbia botany professor and one of the study's authors.
In fact, a recent article on horizontal or lateral gene transfer cites Lederberg and Tatum's 1946 paper as its first reference (McInerney & Pisani, 2007).
Contributors also cover basic evolutionary systems biology, the origin of new genes, lateral gene transfer, the evolution of genomic expression, the evolution of proteome complexity and diversity, genomic redundancy and dispensability, genome defense, sex-biased genomic expression, sex chromosome origins and evolution, molecular signatures of adaptive evolution, gene networks and natural selection, and human evolutionary genomics.
The finding has important biomedical implications because such gene-swapping, or lateral gene transfer, is the way many pathogenic bacteria pick up antibiotic resistance or become virulent.
One difficulty stems from microbial infidelity known as horizontal or lateral gene transfer.
