Also multi-locus genes, including both mitochondrial and nuclear genomes and additional taxa, will need to be analysed to provide informative characters to resolve the phylogeny among Caridean groups.
Whether C. preissii, M. nipponense, P. elegans and P. tarda exhibit taxonomically significant geographic variation and/ or comprise cryptic species should be reviewed with additional morphological, as well as population genetic and molecular systematic studies with multi-locus genes.
A rapid multi-loci gene analysis system was developed that achieved high sensitivity, was reproducible, and provided three-tier sequence-specific interrogation of DNA targets.
This indicates that phylogenetic classification of genus Brucella based on marker genes, for instance multi locus sequence typing [ 22], show a surprising similarity to the organism's total gene content.
A detailed analysis of the ibeA sequences revealed the phylogeny of this gene to be consistent with that obtained by Multi Locus Sequence Typing of the strains.
Isolates were classified in clonal groups based upon sequence analysis of conserved house-keeping genes and comparison of the results with the data on the Neisseria Multi Locus Sequence Typing website (http://pubmlst.org/neisseria/) [ 44].
However, recent MLSA (multi locus sequence analyses) analyses showed that this strain, which does not possess the albicidin biosynthesis gene cluster, is close to X. albilineans but belongs to a separate phylogenetic clade (I. Pieretti, unpublished data).
Multi locus sequence typing (MLST) based phylogenetic analysis was performed for Xcaw12879 and other Xanthomonas spp. using nine housekeeping genes (uvrD, secA, carA, recA, groEL, dnaK, atpD, gyrB, and infB) that are highly conserved in bacteria.
For other gene loci, prototype sequences needed for the design of MLST were obtained from the genomes of L. interrogans serovar Lai (NC_004342 and NC_004343) and L. interrogans serovar Copenhageni (NC_005823 and NC_005824) The multi locus sequences of all the 271 isolates obtained as a part of this study are available in full under supporting information (Table S2).
Isolates of S. suis were serotyped and characterized by multi locus sequence typing (MLST) and pulse field gel electrophoresis (PFGE).
MLST: Multi locus sequence typing; ST: Sequence type.
