Lineage: Pectobacterium atrosepticum; Pectobacterium; Enterobacteriaceae; Enterobacteriales; Proteobacteria; Bacteria

General Information: This strain (ATCC BAA-672) is a virulent blackleg isolated from the stem of a potato plant. Causative agent for blackleg and soft rot disease in potatoes. Formerly Erwinia, these organisms are plant-specific pathogens that invade the vascular systems of plants. Both Pectobacterium chrysanthemia and Pectobacterium carotovora cause soft-rot diseases of various plant hosts through degradation of the plant cell walls. Pectobacterium colonize the intercellular spaces of plant cells and deliver potent effector molecules (Avr - avirulence) through a type III secretion system (Hrp - hypersensitive response and pathogenicity). Avr proteins control host-bacterium interactions, including host range. Expression of the plant cell-wall-degrading enzymes is controlled through a quorum-sensing mechanism that quantifies the number of Pectobacterium bacteria through measurement of the concentration of small molecules (acyl homoserine lactones) produced by Pectobacterium. Pectobacterium atrosepticum is an environmentally widespread organism that causes blackleg and soft rot disease in potatoes. This organism produces pectolytic enzymes that destroy plant tissue and allow the bacteria to spread.

Subject: NC_006449:345396 Streptococcus thermophilus CNRZ1066, complete genome

Lineage: Streptococcus thermophilus; Streptococcus; Streptococcaceae; Lactobacillales; Firmicutes; Bacteria

General Information: This strain was isolated from yogurt in France. Lactic acid producing bacterium used in cheese and yogert production. Streptococci are Gram-positive, nonmotile, nonsporeforming, catalase-negative cocci that occur in pairs or chains. Members of this genus vary widely in pathogenic potential. Most streptococci are facultative anaerobes, and some are obligate anaerobes. Serologic grouping is based on antigenic differences in cell wall carbohydrates, in cell wall pili-associated protein, and in the polysaccharide capsule in group B streptococci. This organism is a lactic acid bacteria often used as a starter culture for fermented dairy products including yogurt and cheese.
