General Information: This organism, also known as BT, is famous for the production of an insecticidal toxin. The bacterium was initially discovered as a pathogen of various insects and was first used as an insecticidal agent in the early part of this century. This organism, like many other Bacilli, is found in the soil, where it leads a saprophytic existence, but becomes an opportunistic pathogen of insects when ingested. The specific activity of the toxin towards insects and its lack of toxicity to animals has made this organism a useful biocontrol agent. The delta-endotoxin, which is produced during the sporulation part of the life cycle, causes midgut paralysis and disruption of feeding by the infected insect host. The delta-endotoxin, which is produced during the sporulation part of the life cycle, causes midgut paralysis and disruption of feeding by the infected insect host. The delta-endotoxin, which is produced during the sporulation part of the life cycle, causes midgut paralysis and disruption of feeding by the infected insect host. The presence of a parasporal crystal, which is outside the exosporium of the endospore, is indicative of production of the toxin, and serves as a marker for this species.Activation of the toxin typically requires a high pH environment such as the alkaline environments in insect midguts followed by proteolysis.

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.
