Sinorhizobium meliloti strain USDA1883

Sinorhizobium meliloti strain USDA1883 is a gram-negative, aerobic bacterium characterized by its rod shape and mobility, enabled by the presence of flagella. It thrives optimally at a temperature of 25°C, placing it within the mesophilic temperature range. This strain contains a single replicon, which is typical for many bacteria. USDA1883 is notable for its symbiotic relationship with a variety of host plants, including Medicago truncatula, Cicer arietinum, Indigofera sp., and several species of Medicago and Melilotus. This diverse host range indicates its ecological versatility and ability to form effective nodules on leguminous plants, facilitating nitrogen fixation. This ability is crucial for enhancing soil fertility and supporting sustainable agricultural practices, particularly in environments where these plant species are cultivated. The presence of multiple habitats suggests that Sinorhizobium meliloti strain USDA1883 can adapt to various environmental conditions, potentially contributing to its success in colonizing diverse plant hosts. Understanding the ecological roles of this strain can inform agricultural practices, particularly in legume cultivation, where its nitrogen-fixing capabilities can improve crop yields and soil health. The strain's adaptability and beneficial interactions with host plants underscore its importance in both ecology and agriculture.
