“…In the absence of positive nodulation tests, they can be regarded as non-rhizobial endophytes (NRE). These include i.a., Alphaproteobacteria (Aminobacter (Estrella et al, 2009), Ochrobactrum (Zurdo-Pineiro et al, 2007Imran et al, 2010), Methylobacterium (Palaniappan et al, 2010), Devosia (Bautista et al, 2010) and Phyllobacterium (Mantelin et al, 2006)), Betaproteobacteria (Herbaspirillum (Valverde et al, 2003) and Shinella (Lin et al, 2008)), Gammaproteobacteria (Pantoea, Enterobacter and Pseudomonas (Benhizia et al, 2004;Ibañez et al ., 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 R-40421, R-45534, R-45535, R-45537, R-45540, R-45543, 23,30,161,170,188,303,362,375,376,377,378,380,420,421,422,423,424,425,432,…”

Statistical analysis grouped the investigated plant species into six clusters according to the presence of particular NRE. However, no correlations could be found within these six clusters towards plant tribes or ecoregions the plants had been sampled from. Cluster analysis of the ecoregions according to the presence of NRE, revealed correlations between bacterial genera and those areas. However, groups present in the ecoregions did not correlate with the groups present in the different plant clusters. When combining our previous study on rhizobial diversity recovered from the same sampling campaign (De Meyer et al., 2011) with the current study, 84.1% of the isolates belonged to the traditional rhizobia groups and only 15.9% were NRE. The Loamy ecoregion yielded the lowest number of culturable NRE (8.04%) and the Campine ecoregion the highest number (24.19%). The present study highlights the frequent presence of these NRE in root nodules. The occurrence of certain rhizobia was correlated with the presence of particular NRE, suggesting their presence may not be accidental, however their functions remain unclear at this point.

“…Molecular data have shown that rhizobial bacteria actually constitute a polyphyletic assemblage of alpha, beta and gamma proteobacteria, which collectively form the order Rhizobiales [7][8][9]. The rhizobia-legume symbiosis exhibits great host specificity, but so far complete information of host specificity is not available.…”

“…[146][147][148] Nevertheless as Benhizia et al 146 say they could nodulate legumes since recently it has been reported the legume symbiosis may exist in absence of nod genes as occurs in the case of photosynthetic bradyrhizobia.…”

Over the years, the term "rhizobia" has come to be used for all the bacteria that are capable of nodulation and nitrogen fixation in association with legumes but the taxonomy of rhizobia has changed considerably over the last 30 year. Recently, several nonrhizobial species belonging to alpha and beta subgroup of Proteobacteria have been identified as nitrogen-fixing legume symbionts. Here we provide an overview of the history of the rhizobia and the widespread phylogenetic diversity of nitrogen-fixing legume symbionts.
