Complete Taxonomy
Description
Synchytrium endobioticum is an obligate parasite of potato plants, causing black wart disease. This devastating pathogen induces tumor-like growths on tubers and stems, rendering potatoes unmarketable. Resting spores can survive in soil for decades. It's a quarantine pathogen in many countries, and infected fields may be banned from potato cultivation. Resistant potato varieties are the primary control method.
Physical Characteristics
Distribution
Europe, parts of Asia, Africa, and Americas; quarantine restrictions limit spread
Habitat
Obligate parasite of potato (Solanum tuberosum) and related species. Survives as resting spores in soil for 30+ years.
Ecological Role
Highly specialized obligate parasite of Solanaceae, particularly potato. Regulates susceptible host populations in natural systems.
Cultural Significance
Major agricultural quarantine pathogen. Subject of strict regulations globally. Historical economic impact led to development of resistant potato varieties and quarantine systems.
Fascinating Facts
- Resting spores survive in soil for 30-40 years
- Can destroy entire potato crops
- Quarantine pathogen in most countries
- Resistant potato varieties bred specifically against this disease
- Infected fields may be prohibited from growing potatoes for decades
- Only affects potato and related Solanaceae
- Spread through infected tubers and contaminated soil
- Intracellular parasite - lives inside plant cells
