| Abstract: | Leucaena leucocephala is a Mimosoid legume tree indigenous to America that has spread to other continents, although it is not still present in some European countries such as Portugal. Nevertheless, we found that this legume can be nodulated in this country by slow-growing rhizobial strains which were identified as Bradyrhizobium canariense trough the analysis of the core genes recA and glnII. The analysis of the symbiotic gene nodC showed that these strains belong to the symbiovar genistearum, which commonly nodulates Genistoid legumes. Although two strains nodulating L. leucocephala in China and Brazil were classified within the genus Bradyrhizobium, they belong to undescribed species and to the symbiovars glycinearum and tropici, respectively. Therefore, we report here for the first time the ability of L. leucocephala to establish symbiosis with strains of B. canariense sv genistearum confirming the high promiscuity of L. leucocephala, that allows it to establish symbiosis with rhizobia native to different continents increasing its invasiveness potential. |
