Beyond the interest these lateral gene transfers evoke in evolutionary biology, these results highlight the risk gene transfers could cause, in case GM - parasitoid wasps are produced, as genes artificially introduced into wasp species used for biological control could be transferred into the genomes of the targeted pests.
It had been assumed that such lateral gene transfers were uncommon, but their existence in arthropods, the largest animal phylum, suggests that such transfers may be a significant evolutionary mechanism.
They would be created through the process of lateral gene transfer, in which microbes incorporate loose bits of genetic material from other microbes into their own.
Lateral gene transfer is the...
Research areas include species for comparative research; phenotypic characterization; fitness, genome stability and lateral gene transfer; control of organismal traits; monitoring and surveillance; modeling and standardization of methods and data.
«This is the strongest evidence to date for lateral gene transfer,» says molecular evolutionist Ford Doolittle of the Canadian Institute for Advanced Research in Halifax, Nova Scotia.
It focused on flagging sources of uncertainty and evaluating methods of testing fitness, genetic stability and lateral gene transfer.
Phylogenomic analysis identifies evidence for lateral gene transfer of bacterial genes into the E. histolytica genome, the effects of which centre on expanding aspects of E. histolytica's metabolic repertoire.
New coding genes can arise in genomes through several processes, including gene duplication, gene fusion, de novo formation from non-coding DNA, or lateral gene transfer (LGT) from another species.
The explosion in the number of newly sequenced genomes provides opportunities to identify and characterize examples of these lateral gene transfer events, and to assess their role in the evolution of new genes.
Deletion of the TAM from a naive strain of E. coli results in a drastic time delay in folding of UshC, which can be observed for a protein from EPEC as well as for two introduced proteins from related organisms, Yersinia and Enterobacter We suggest that this models why the TAM machinery is essential for efficient folding of proteins acquired via lateral gene transfer.

This narrow view has been becoming overshadowed by genetic findings that support the more recent hypothesis of complex roots, which emphasizes lateral genetic exchanges or horizontal gene transfers (HGT) rather than vertical mutational progression in the development of nucleated organisms, through a clearly defined «tree of life» (Mark Buchanan, New Scientist, January 26, 2010).
