Query: NC_008686:1960034 Paracoccus denitrificans PD1222 chromosome 1, complete sequence
Lineage: Paracoccus denitrificans; Paracoccus; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This organism is commonly found in soil and sewage sludge. This organism is able to survive in both aerobic and anaerobic environments due to its ability to use both oxygen and nitrogenous oxides making it a popular model organism for the study of electron transfer and and energy conservation.
Subject: NC_002678:2739829 Mesorhizobium loti MAFF303099, complete genome
Lineage: Mesorhizobium loti; Mesorhizobium; Phyllobacteriaceae; Rhizobiales; Proteobacteria; Bacteria
General Information: Plant symbiont bacterium. This organism contains a symbiosis island that is responsible for symbiotic relationships with plants (lotus) which is similar to what is observed with other Rhizobia that form similar relationships with legumes. The bacterium enters root nodules and performs nitrogen-fixation for the plant cell while being provided with a protective environment to grow in. Nitrogen fixation and root nodule formation genes are carried on a symbiosis island.
