Lima bean (Phaseolus lunatus L.) is an important legume species that establishes symbiosis with rhizobia, mainly of the Bradyrhizobium genus. The aim of this study was to evaluate the efficiency of rhizobia of the genus Bradyrhizobium in symbiosis with lima bean, in both Leonard jars and in pots with a Latossolo Amarelo distrófico (Oxisol). In the(More)
Plants on contaminated mining soils often show a reduced growth due to nutrient depletion as well as trace elements (TEs) toxicity. Since those conditions threat plant's survival, plant growth-promoting rhizobacteria (PGPRs), such as rhizobia, might be of crucial importance for plant colonization on TE-contaminated soils. Native rhizobia from mining soils(More)
The symbiosis of Leguminosae with arbuscular mycorrhizal fungi (AMF) and N2-fixing nodulating bacteria (NFNB) can occur simultaneously, forming a tripartite symbiosis. In particular, AMF can colonize root nodules, although this interaction is not yet well elucidated, especially with regard to nodule activity and to the influence of external factors, such as(More)
Four strains of rhizobia isolated from nodules of Vigna unguiculata (UFLA03-321T, UFLA03-320 and UFLA03-290) and Macroptilium atropurpureum (UFLA04-0212) in Brazilian soils were previously reported as a new group within the genus Bradyrhizobium. To determine their taxonomic position, these strains were characterized in this study using a polyphasic(More)
