Query: NC_010544:850502 Candidatus Phytoplasma australiense, complete genome
Lineage: Phytoplasma australiense; Phytoplasma; Acholeplasmataceae; Acholeplasmatales; Tenericutes; Bacteria
General Information: Phytoplasmas inhabit phloem (food-conducting vascular tissue) sieve elements of plants where they cause a variety of diseases. Transmission between plants is via insects that feed on the phloem. Candidatus Phytoplasma australiense was identified in diseased Chardonnay grapevines from South Australia. Symptoms include a yellowing of the leaves and reduced leaf size, which leads to reduced plant size and lower yields.
Subject: NC_014034:3570034 Rhodobacter capsulatus SB1003 chromosome, complete genome
Lineage: Rhodobacter capsulatus; Rhodobacter; Rhodobacteraceae; Rhodobacterales; Proteobacteria; Bacteria
General Information: This strain is a derivative strain isolated in the laboratory of Barry Marrs from the classical progenitor strain B10. It is rifampicin-resistant, produces GTA, and is capable of growing under high illumination (resistant to photooxidative killing). Bacteria belonging to the Rhodobacter group are metabolically versatile as they are able to use photosynthesis and usually can grow under both anaerobic and aerobic conditions. This organism is a facultatively phototrophic purple non-sulfur bacterium and the type species of the Rhodobacter group. The colony's color depends largely on the amount of oxygen present in its environment. While it is able to produce cellular energy in a number of different ways, it can rely on anoxygenic photosynthesis under anaerobic conditions in the presence of light. Some strains produce the Gene Transfer Element (GTA), a pro-phage particle capable of transferring genetic material between strains.
