“…The genus Rhizobium was represented by four species of bacteria which are Rhizobium pusense, Rhizobium leguminosarum, Rhizobium phaseoli and Rhizobium tropici. These species were previously isolated from common bean nodules by Gunnabo et al [25] in Ethiopia; Torrez-Gutiérrez et al [26] in Ecuador and by Gunununu et al [27] in Eswatini. These species are considered to be the predominant species isolated from bean nodules in the Andean region, their native area [25,28].…”

“…Motilonia en los cinco genotipos no presentaron nódulos, posiblemente se deba a que no hay rizobios nativos específicos con los que puedan asociarse simbióticamente o debido a la influencia de factores que limitan este proceso. La asociación simbiótica y la nodulación depende del genotipo de la planta, la bacteria y las condiciones ambientales o del suelo (Torres-Gutiérrez et al, 2021), las condiciones ambientales estresantes limitan los procesos de nodulación afectando negativamente la simbiosis rizobio-leguminosa (Shankar et al, 2021;Villanueva, 2021). Otra posible explicación puede ser la disponibilidad de nitrógeno en el cultivo, ya que en este ensayo las plantas fueron fertilizadas teniendo en cuenta la deficiencia de nitrógeno en el suelo y los requerimientos del cultivo, cuya fertilización incluyó fuentes nitrogenadas.…”
