| Rhizobium leguminosarum bv. viciae is an endosymbiotic bacterium capable of establishing effective associations with legumes belonging to different genera, including Pisum, Lens, Vicia and Lathyrus. Several host-dependent symbiotic bacterial phenotypes have been described for this bacterium when associated with different members of this cross-inoculation group, namely pea and lentil: i) hydrogenase expression, leading to recycling the hydrogen produced by the nitrogenase, occurs in pea nodules but not in lentil (Brito et al., 2008); ii) nickel transport required for hydrogenase synthesis occurs differently when bacteroids are induced in lentil vs. pea nodules (Brito et al., 2010); and iii) the interaction between mechanisms of nickel uptake and efflux are different in both hosts (Rubio-Sanz et al., 2013). These differences suggest that legumes in the same cross-inoculation group can modulate differently the microsymbiont?s behaviour during the symbiosis. The study of these differences may help to better understand the involvement of the plant in the complex interaction between the two components during symbiosis. | |
