Agrobacterium tumefaciens strain 186

Agrobacterium tumefaciens strain 186 is a gram-negative, rod-shaped bacterium that plays a significant role in plant pathology, particularly through its association with viridiplantae hosts. This microbe is an aerobe and exhibits mobility due to the presence of flagella, which facilitates its movement in various habitats. The optimal growth temperature for this strain is 25°C, and it thrives within a mesophilic temperature range. Strain 186 is notable for its biotic relationship as a free-living organism and is known to infect a wide variety of plant hosts, including Triticum aestivum (wheat), Solanum tuberosum (potato), Solanum lycopersicum (tomato), and Oryza sativa (rice), among others. The bacterium is infamous for causing crown gall disease, characterized by tumor formation on infected plants. The disease manifests through crown and cane gall symptoms, which can significantly impact plant health and agricultural yield. The genetic makeup of Agrobacterium tumefaciens strain 186 is complex, comprising four replicons and two membranes, which are characteristic of its intracellular processes. The presence of multiple accessions, including NZ_CP042274.1, NZ_CP042276.1, NZ_CP042277.1, and NZ_CP042275.2, indicates the strain's genetic diversity and adaptability. Ecologically, A. tumefaciens serves as a model for understanding plant-microbe interactions and the mechanisms underlying tumorigenesis in plants. Its ability to transfer genetic material to host plants has implications for biotechnology, particularly in the development of genetically modified crops. Thus, studying this strain contributes valuable insights into both plant pathology and agricultural biotechnology.
