Rhizobium leguminosarum strain SM145A frag_SM145A_18

Rhizobium leguminosarum strain SM145A frag_SM145A_18 is a Gram-negative, rod-shaped bacterium that thrives in soil environments. As a chemoheterotroph, it acquires energy from organic compounds, demonstrating its adaptability to nutrient-rich substrates typically found in soil ecosystems. This strain is aerobic, requiring oxygen for growth, and is mobile due to the presence of flagella. With a mesophilic temperature range, Rhizobium leguminosarum strain SM145A can grow optimally within moderate temperature conditions, making it well-suited for various temperate climates. The organism exhibits a simple cellular arrangement, occurring as single cells, and possesses two membranes indicative of its Gram-negative classification. This strain has a symbiotic relationship with several host plants, including Lens culinaris, Trifolium ambiguum, Vavilovia formosa, Medicago sativa, Lathyrus oleraceus, Trifolium pratense, Trifolium rubens, and Trifolium repens. Such symbiosis is crucial for nitrogen fixation, allowing host plants to thrive in nitrogen-poor soils. Nonsporulating in nature, Rhizobium leguminosarum strain SM145A relies on its ability to form symbiotic associations rather than producing spores for survival. This trait highlights the importance of its ecological role in supporting plant health and enhancing soil fertility through nitrogen fixation. Overall, Rhizobium leguminosarum strain SM145A contributes significantly to sustainable agricultural practices by improving plant growth and soil quality.
