Query: NC_010544:671431 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_004829:64000 Mycoplasma gallisepticum R, complete genome
Lineage: Mycoplasma gallisepticum; Mycoplasma; Mycoplasmataceae; Mycoplasmatales; Tenericutes; Bacteria
General Information: Causes respiratory disease in birds. This genus currently comprises more than 120 obligate parasitic species found in a wide spectrum of hosts, including humans, animals, insects and plants. The primary habitats of human and animal mycoplasmas are mucous membranes of the respiratory and urogenital tracts, eyes, mammary glands and the joints. Infection that proceeds through attachment of the bacteria to the host cell via specialized surface proteins, adhesins, and subsequent invasion, results in prolonged intracellular persistence that may cause lethality. Once detected in association with their eukaryotic host tissue, most mycoplasmas can be cultivated in the absence of a host if their extremely fastidious growth requirements are met.
