“…The legumes were not inoculated, and native rhizobia populations compatible with the legume species could be absent in the soil. This is unlikely to be the case in relation to cowpea, a promiscuous species (Jaramillo et al, 2013), which had high proportions of N derived from biological fixation when planted in the region without inoculation (Freitas et al, 2012). Indeed, cowpea plants had more than 60% N derived from fixation, both in the traditional and agroforestry systems, a performance similar to those already reported for most of the local varieties tested by Freitas et al (2012) in single crop systems.…”

“…Groups formed in each site were higher than the reference strains (SEMIA 6461 and SEMIA 6462). In São Raimundo das Mangabeiras, results of the number and dry matter of nodules described above demonstrate the ability of the native population to establish symbiosis with cowpea, which is a promiscuous legume species (MOREIRA; SIQUEIRA, 2006;GUIMARÃES et al, 2012;JARAMILLO et al, 2013). The highest values of number of nodules and nodules dry matter of treatments with UFLA 3-153, UFLA 3-154 and UFLA 3-164 strains achieved in both experiments corroborate with Soares et al (2014), who evaluated the symbiotic efficiency of the same strains in cowpea in axenic conditions and in pots filled with soil.…”

Contudo, os gêneros Paenibacillus e Bacillus geralmente são endofíticos de nódulos, mas não nodulíferos, embora haja relatos da nodulação em feijão-caupi por esses dois gêneros (Marra et al, 2012;Jaramillo et al, 2013).…”

Alguns autores têm sugerido que algumas bactérias endofíticas de nódulos poderão evoluir para bactérias simbióticas por meio da transferência horizontal de genes simbióticos (Li et al, 2008;Shiraishi et al, 2010).…”
