RESEARCH INTERESTS:
The focus of my research is lateral gene transfer (LGT) between and within Bacteria and Archaea. The Thermotogales are of particular interest, since the genome of Thermotoga maritima suggests that one quarter of its genes are of archaeal origin. In order to determine the level of LGT and recombination in Thermotoga, I have been using degenerate PCR and suppressive subtractive hybridization, as well as sequencing of lambda- and fosmid clones containing genes of interest such as rRNA genes. These experimental approaches are combined with detailed phylogenetic analyses. I have also been working with self-splicing group I introns that I discovered in the 23S rRNA of some Thermotoga strains. Presently we are working on isolating new Thermotogales strains for a MLST study to get information on population structure and biogeography of this bacterial group. We are also involved sequencing the genome of an additional Thermotogales strain, Thermosipho africanus. I am currently doing the phylogenetic and bioinformatic analyses of this genome. We recently identified, using a metagenomic approach, a new Thermotogales lineage which grows at cold temperatures and that we informally call ‘mesotoga’, and we are currently working with getting a isolate of this new genus characterized.To get information on the extent of LGT occurring among prokaryotes present in the environment, we have been sequencing rRNA-containing fosmid clones from fosmid libraries of DNA extracted from environmental samples. Phylogenetic trees of the ORFs encoded on these genomic fragments are compared to rRNA phylogenies. In addition to looking at environmental rRNA containing fosmid clones, I am also involved in projects where we are investigating distribution of environmental integrons and integron gene cassettes in different polluted and pristine environments.
