Query: NC_014814:859124 Mycobacterium sp. Spyr1 chromosome, complete genome
Lineage: Mycobacterium gilvum Spyr1; Mycobacterium; Mycobacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Country: Greece; Environment: Creosote-contaminated soil, Soil; Temp: Mesophile; Isolation: creosote contaminated soil; Country:Greece: near Ioannina, Epirus. Like other closely related Actinomycetales, such as Nocardia and Corynebacterium, mycobacteria have unusually high genomic DNA GC content and are capable of producing mycolic acids as major components of their cell wall. These organism are common in soil and freshwater.
Subject: NC_008278:3601959 Frankia alni ACN14a, complete genome
Lineage: Frankia alni; Frankia; Frankiaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: This strain was isolated from a green alder (Alnus crispa) growing in Tadoussac, Canada. These bacteria were originally linked to fungi, because of the mycelium-like filaments many of them form. This bacterium is able to establish a nitrogen-fixing symbiosis with alder (Alnus spp.) and myrtle (Myrica spp.), two pioneer plant genera of temperate regions, found on forest clearings, mine wastes, sand dunes and glacial moraines where nitrogen is the limiting factor. Frankia alni causes root hair deformation: it penetrates the cortical cells and induces the formation of nodules which resemble those induced by Rhizobium in legumes. These nodules are then colonized by vegetative hyphae (mycelium filaments) which differentiate into diazo-vesicles
