Query: NC_009380:2253500 Salinispora tropica CNB-440 chromosome, complete genome
Lineage: Salinispora tropica; Salinispora; Micromonosporaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: This strain was isolated from coarse beach sand off the Bahamas. An obligate marine actinomycete. Salinispora strains are commonly isolated from tropical marine sediment. Members of this genus produce branched hyphae and require media which contain seawater or sodium. A survey of the cultured species identified over 90 isolates which produce compounds that inhibited cancer cells. These organisms may be a new source of bioactive chemicals for use in disease and cancer treatments. This species produces the chemicals salinosporamide A and B which may be useful for cancer treatment.
Subject: NC_009480:2932108 Clavibacter michiganensis subsp. michiganensis NCPPB 382, complete
Lineage: Clavibacter michiganensis; Clavibacter; Microbacteriaceae; Actinomycetales; Actinobacteria; Bacteria
General Information: Phytopathogen that causes bacterial wilt and canker of tomato (Lycopersicon esculentum). This is considered to be the most important bacterial disease of tomato causing substantial economic losses worldwide. Bacteria enter the plant by wounds on root or stem and then find their way into the xylem allowing a massive systemic colonization. The first stage of the disease is characterized by unilateral wilting of leaves. Wilting then spreads to all leaves, canker lesions develop on the stem and the plant dies. If infection occurs at a late stage of plant development, plants can survive and yield fruit that may have spots, so called bird's eyes. Often the seeds will be infected and this has been the major source for outbreaks of Clavibacter michiganensis subsp. michiganensis infections in agriculture. Members of the Clavibacter genus are known to produce antimicrobial compounds.
