Abstract：
Phaseolus vulgaris L. (common bean) is a legume indigenous to American countries currently cultivated in all continents, which is nodulated by different rhizobial species and symbiovars. Most of species able to nodulate this legume worldwide belong to the genus Rhizobium, followed by those belonging to the genera Ensifer (formerly Sinorhizobium) and Pararhizobium (formerly Rhizobium) and minority by species of the genus Bradyrhizobium. All these genera belong to the phylum alpha-Proteobacteria, but the nodulation of P. vulgaris has also been reported for some species belonging to Paraburkholderia and Cupriavidus from the beta-Proteobacteria. Several species nodulating P. vulgaris were originally isolated from nodules of this legume in American countries and are linked to the symbiovars phaseoli and tropici, which are currently present in other continents probably because they were spread in their soils together with the P. vulgaris seeds. In addition, this legume can be nodulated by species and symbiovars originally isolated from nodules of other legumes due its high promiscuity, a concept currently related with the ability of a legume to be nodulated by several symbiovars rather than by several species. In this article we review the species and symbiovars able to nodulate P. vulgaris in different countries and continents and the challenges on the study of the P. vulgaris endosymbionts diversity in those countries where they have not been studied yet, that will allow to select highly effective rhizobial strains in order to guarantee the success of P. vulgaris inoculation.
摘要：
菜豆（普通豆）是目前在各大洲种植的美洲国家的豆科植物，由不同的根瘤菌和共生菌结瘤。世界上大多数能够结瘤这种豆科植物的物种都属于根瘤菌属，其次是属于Ensifer属（以前是中华根瘤菌属）和Pararhizobium属（以前是根瘤菌属）和少数根瘤菌属。所有这些属都属于α-变形杆菌门，但是，也有报道称，来自β-变形杆菌的某些属于Paraburkholderia和Cupriavidus的物种也出现了寻常型疟原虫的结瘤。最初在美洲国家从这种豆科植物的结节中分离出几种结瘤的普通P.vulgaris，并与共生的phaseoli和tropici有关。它们目前存在于其他大陆，可能是因为它们与普通品系种子一起在土壤中传播。此外,由于这种豆科植物的高滥交性，这种豆科植物可以被最初从其他豆科植物的结节中分离出来的物种和共生体结瘤，目前与豆科植物被几个共生生物而不是几个物种结瘤的能力有关的概念。在本文中，我们回顾了能够在不同国家和大陆结瘤寻常型疟原虫的物种和共生体，以及在尚未研究它们的国家研究寻常型疟原虫内共生体多样性的挑战。这将允许选择高效的根瘤菌菌株，以保证寻常型假单胞菌接种的成功。
