Sinorhizobium meliloti strain M162

Sinorhizobium meliloti strain M162 is a Gram-negative, aerobic bacterium characterized by its rod shape and mobility, facilitated by the presence of flagella. This strain thrives optimally at a temperature of 25°C and falls within the mesophilic temperature range. Notably, it possesses three replicons, which may contribute to its genetic diversity and adaptability. The ecological role of S. meliloti strain M162 is particularly significant due to its symbiotic relationships with various host plants, including Medicago truncatula, Cicer arietinum, and several species within the Fabaceae family, such as Acacia and Glycine. These interactions are vital for the nitrogen-fixing process, which enhances soil fertility and supports plant growth. Given its adaptability to multiple habitats and its ability to form beneficial associations with a wide range of leguminous plants, S. meliloti strain M162 plays an essential role in sustainable agricultural practices. By contributing to nitrogen fixation, it supports the growth of host plants and can improve soil health, highlighting the importance of microbial symbionts in ecological and agricultural systems. The strain's genetic makeup, represented by its accessions (NZ_CP021818.1, NZ_CP021819.1, NZ_CP021820.1), may also provide insights into its functional capabilities and interactions within different environments.
