Diversity of nitrogen fixation genes in the symbiotic intestinal microflora of the termite Reticulitermes speratus
Article Abstract:
Phylogenic analysis of nifH genes clonally isolated from the DNA of the mixed microbial population of Reticulitermes speratus demonstrates diverse N2 fixation genes within microbial population. While many of the nifH sequences are closely related to those of a firmicute, a few are related to either the gamma subclass of proteobacteria or a sequence of Desulfovibrio gigas. Such diversity may be a result of the presence of alternative nitrogenase genes and several copies of nifH in the N2-fixing microorganism.

The motility symbiont of the termite gut flagellate Caduceia versatilis is a member of the "Synergists" group
Article Abstract:
The ectosymbionts were identified by a combination of clone analyses and fluorescence in situ hybridization (FISH) analyses of 16SrRNA. Results concluded that motility ectosymbiont evolved from a free-living, gut bacterium within this termite-specific cluster.
