Query: NC_014311:1507945 Ralstonia solanacearum PSI07 chromosome, complete genome
Lineage: Ralstonia solanacearum; Ralstonia; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: This organism is a phytopathogen that is found in the soil and causes systemic wilting disease in many important food crops such as tomatoes, potatoes, bananas, tobacco, pepper, peanut, ginger, and eucalyptus. It can infect plants found in over 50 different families and this pathogen can be carried asymptomatically in some species.
Subject: NC_001263:2461941 Deinococcus radiodurans R1 chromosome 1, complete sequence
Lineage: Deinococcus radiodurans; Deinococcus; Deinococcaceae; Deinococcales; Deinococcus-Thermus; Bacteria
General Information: This red-pigmented organism's name means "strange berry that withstands radiation", marking the fact that this organism is one of the most radiation-resistant known. It can tolerate radiation levels at 1000 times the levels that would kill a human and it was originally isolated in 1956 from a can of meat that had been irradiated with X-rays. The resistance to radiation may reflect its resistance to dessication, which also causes DNA damage. This organism may be of use in cleaning up toxic metals found at nuclear weapons production sites due to the radiation resistance. This bacterium is also a highly efficient transformer, and can readily take up exogenous DNA from the environment, which may also aid DNA repair. This organism carries multiple copies of many DNA repair genes, suggesting a robust system for dealing with DNA damage. The recombination system may rely on multiple copies of various repeat elements found throughout the genome.
