“…viciae is the sole symbiovar able to establish effective N 2 -fixing symbiosis with V. faba [2], even though it could be present in different chromosomal backgrounds [3,13,25,29,33,38,41,56,61,62,66,67,81]. Previous reports have shown that faba bean also establishes effective nitrogen fixation symbiosis with R. etli in China, Peru and Egypt [56,57,61], R. fabae in China [9,62], R. laguerreae in Algeria, Peru, Spain, and Tunisia [5,6,55,56], R. mesosinicum in China [74], R. anhuiense, R. sophorae and R. vallis in China [9,82], the unidentified lineages Rhizobium sp. I and II in China [9,74], and Sinorhizobium/Ensifer meliloti in Egypt [57].…”
