Symbiotic nitrogen-fixing bacteria of Mediterranean perennial clover plants. Rhizobium leguminosarum bv. trifolii WSM1325

Rhizobium leguminosarum biovar trifolii WSM1325. This biovar is a symbiont of clover plants and is important commercially as it is used in the agricultural industry. Strain WSM1325 is compatible with many perennial clovers of Mediterranean origin used in farming, such as T. pratense, and is therefore one of the most important clover inoculants but is incompatible with American and African perennial clovers, such as those nodulated by the dissimilar strain WSM2304.
