Efficient but Elusive Rhizobia Fix Nitrogen in the Wild Legumes Bituminaria bituminosa and Coronilla Viminalis.

ABSTRACT: In ecological restoration of degraded natural habitats, revegetation with wild native plants is a priority. Legumes play a key role in this process through nitrogen (N)-fixing symbiosis with rhizobia, obtaining N for their growth and improving soil fertility, which benefits other nonleguminous plants in the environment. This study explores the rhizobia of two wild legumes, Coronilla viminalis and Bituminaria bituminosa, found in a degraded habitat in Lanzarote (Canary Islands). We found these legumes nodulated by highly efficient N-fixing mesorhizobia harboring the symbiovars canariensis and hedysari in Mesorhizobium species distinct from those originally reported to carry these symbiovars. However, isolating these rhizobia was challenging. Despite the good plant development and the pink c
