Query: NC_013771:684966 Cyanobacterium UCYN-A, complete genome
Lineage: Atelocyanobacterium thalassa; Atelocyanobacterium; ; Chroococcales; Cyanobacteria; Bacteria
General Information: UCYN-A cyanobacteria are species of nitrogen-fixing marine cyanobacteria that lack the oxygen producing photosystem II complex of the photosynthetic apparatus, the enzymes of the Calvin and tricarboxylic acid cycles, as well as several enzymes involved in amino acid synthesis. The cyanobacteria live in symbiosis with photosynthetic eukaryotic cells, specifically those of a single-celled species of algae.
Subject: NC_010529:296500 Cupriavidus taiwanensis plasmid pRALTA, complete sequence
Lineage: Cupriavidus taiwanensis; Cupriavidus; Burkholderiaceae; Burkholderiales; Proteobacteria; Bacteria
General Information: Cupriavidus taiwanensis LMG19424 was isolated from the root nodule of the legume Mimosa pudica in Taiwan. Cupriavidus taiwanensis, also called Ralstonia taiwanensis or Wautersia taiwanensis is similar to bacteria from the Agrobacterium and Rhizobium genera that form nitrogen-fixing nodules in the roots of various leguminous plants. However, Cupriavidus taiwanensis is only distantly related to these other root nodule-forming bacteria. In Cupriavidus taiwanensis the nodule formation and nitrogen fixation genes are contained a 0.5Mb plasmid.
