Clavibacter michiganensis subsp. insidiosus strain R1-1

Clavibacter michiganensis subsp. insidiosus strain R1-1 is a Gram-positive, aerobic bacterium characterized by its rod shape and the presence of flagella. It exhibits a cell arrangement of both pairs and singles, and it is non-motile. This strain thrives optimally at a temperature of 25°C and falls within the mesophilic temperature range. The strain is classified as free-living and has a diverse range of host plants, including Triticum aestivum (wheat), Solanum tuberosum (potato), Solanum lycopersicum (tomato), Solanum melongena (eggplant), Zea mays subsp. mays (maize), and Medicago sativa (alfalfa), among others from the Solanaceae, Fabaceae, and Poaceae families. C. michiganensis subsp. insidiosus strain R1-1 is known for its pathogenic effects, which include causing bacterial wilt and canker in various hosts. Specific health effects linked to this strain involve diseases such as Goss's wilt, bacterial canker of pepper, and potato ring rot. It also contributes to bacterial wilt of alfalfa and is pathogenic to eggplant, demonstrating its capacity to affect multiple crops. The presence of four replicons and a single membrane indicates a stable genetic structure that may contribute to its adaptability and pathogenic potential. The ecological significance of this strain lies in its ability to impact agriculture by causing severe plant diseases, which can lead to substantial economic losses in affected crops. Understanding this pathogen's traits is crucial for managing its effects on agricultural productivity.
