What is it about?

Our goal is to look more carefully at a subgroup of the non-pathogenic bacteria in the genus Paraburkholderia. We determined that two sets of microbes, Mycetohabitans and Trinickia, separated out from the main group of environmental and symbiotic strains in Paraburkholderia. Mycetohabitans includes two species that are endosymbionts of the plant pathogen Rhizopus microsprous, whereas Trinickia includes Mimosa-nodulating species, soil bacteria, and one phytopathogen, T. caryophylli.

Why is it important?

Our analysis also looked at the differences in lifestyles of these bacteria, and specifically at whether they were nitrogen fixers, legume nodulators, or phytopathogens, determined whether the genes that were correlated with these lifestyles were present in the respective genomes. Nevertheless, more research needs to be pursued to learn more about the biology of these microbes.


From a personal perspective, I am curious about the differences in lifestyles of bacteria, particular the factors that differentiate symbiosis, commensalism, and pathogenesis.
