Query: NC_011047:255208 Candidatus Phytoplasma mali, complete genome
Lineage: Phytoplasma mali; Phytoplasma; Acholeplasmataceae; Acholeplasmatales; Tenericutes; Bacteria
General Information: Candidatus Phytoplasma mali strain AT was collected in Heidelberg, Germany from a symptomatic apple tree. Candidatus Phytoplasma mali belongs to a group of mycoplasma-like organisms (Mollicutes) that infect plants and insects. This organism causes the economically significant apple proliferation disease in Europe. This disease is characterized by floral and phloem necrosis, wilting or general plant decline. Candidatus Phytoplasma mali can also infect cherry, apricot and plum trees.
Subject: NC_010556:462500 Exiguobacterium sibiricum 255-15, complete genome
Lineage: Exiguobacterium sibiricum; Exiguobacterium; Bacillales Family XII; Bacillales; Firmicutes; Bacteria
General Information: This organism was isolated from a 2-3 million-year permafrost core in Siberia, Russia and can survive and grow rapidly at low temperatures. Analysis of long-term survival of psychrophilic organisms such as this one may aid understanding of the potential growth of organisms in astrobiology. Exiguobacterium sibiricum is a psychrotolerant organism able to grow at temperatures that range from -6 to 40 degrees C. This organism is also able to survive repeated freeze/thaw cycles which may contribute to its ability to survive in cold environments.
