Article Abstract:
A study is conducted to gain insight into forces driving the evolutionary transition to symbiosis and their consequences on the genomic composition of microbial participants. The symbiotic genomes were comparatively analyzed by a heterologous array hybridization approach using Escherichia coli macroarrays to understand how host ecology might influence selection for adaptations in microbial genomes and how initial genome reductions might harness organisms into symbiotic lifestyles.

Article Abstract:
Escherichia coli K-12 strain MG1655 is genetically engineered to eliminate biofilm formation by the deletion of genes involved in the biosynthesis and assembly of curli and colanic acid and type I pilus biosynthesis. The results have indicated that the newly developed biofilm production-deficient strain of E. coli exhibits many vital properties that substantially increase its utility in the biotechnology area.

Article Abstract:
A study determined that Sodalis isolates from several tsetse fly species are virtually identical based on a phylogenetic analysis of their ftsZ gene sequences. Quantitative PCR analysis showed that transinfected flies maintained their Sodalis populations at densities comparable to those in flies harboring native symbionts.
