“…1), but the majority of them corresponded to the genus Rhizobium. Ensifer isolates with 16S rRNA gene sequence similarities over 99.6 % to the type strains of Ensifer mexicanus (Lloret et al, 2007), Ensifer terangae or Ensifer saheli (Delajudie et al, 1994) were obtained only from a single site (Ocuilan de Juárez) with alkaline soils (pH 8) while all other nodule isolates were from acid soils (Table S1). A sequence affiliated with members of the genus Mesorhizobium with 99.8 % sequence similarity to Mesorhizobium plurifarium LMG 11892 T (de Lajudie et al, 1998) was obtained from Laguna Bélgica.…”

“…Probability ranges (P50.01) of gene identities within and between species (interspecies and intraspecies variability) were estimated to discriminate between species, as described previously (Lloret et al, 2007;Martínez-Romero et al 2010). Intraspecies 99 % confidence intervals for the three new lineages and the three genes considered (atpD, recA and rpoB) showed that the variability of each gene is significantly smaller in a single lineage (intraspecies) than among closely related species (Fig.…”

Calliandra grandiflora has been used as a medicinal plant for thousands of years in Mexico. Rhizobial strains were obtained from root nodules of C. grandiflora collected from different geographical regions in Chiapas and characterized by BOX-PCR, amplified rDNA restriction analysis (ARDRA) and 16S rRNA gene sequence analysis. Most isolates corresponded to members of the genus Rhizobium and those not related to species with validly published names were further characterized by recA, atpD, rpoB and nifH gene phylogenies, phenotypic and DNA–DNA hybridization analyses. Three novel related species of the genus Rhizobium within the ‘ Rhizobium tropici group’ share the same symbiovar that may be named sv. calliandrae. The names proposed for the three novel species are Rhizobium calliandrae sp. nov. (type strain, CCGE524T = ATCC BAA-2435T = CIP 110456T = LBP2-1T), Rhizobium mayense sp. nov. (type strain, CCGE526T = ATCC BAA-2446T = CIP 110454T = NSJP1-1T) and Rhizobium jaguaris sp. nov. (type strain, CCGE525T = ATCC BAA-2445T = CIP 110453T = SJP1-2T).

“…The reference strain of 'E. mexicanus' LMG 23932, which was described recently (Lloret et al, 2007), was related to these taxa. It was not included in our analyses, but formed a distinct subclade, sharing sequence similarity values of 97.8-98.8 % with clusters A, B and C and 99.5 % with strains of E. terangae.…”

Nine isolates from Argyrolobium uniflorum, Lotus creticus, Medicago sativa (Tunisia) and Lotus arabicus (Senegal) were analysed by multilocus sequence analysis (MLSA) of five housekeeping genes (recA, atpD, glnA, gltA and thrC), the 16S rRNA gene and the nodulation gene nodA. Analysis of the individual and concatenated gene sequences demonstrated that the nine new strains constituted three stable, well-supported (bootstrap and gene sequence similarity values) monophyletic clusters, A, B and C, all belonging to the branch of the genus Ensifer, regardless of the phylogenetic reconstruction method used (maximum likelihood, maximum-parsimony, neighbour-joining). The three groups were further characterized by API 100 auxanographic tests, host specificity and nodA gene sequence analysis. On the basis of these data, clusters A and C are suggested as representing two novel species within the genus Ensifer, for which the names Ensifer numidicus sp. nov. (type strain ORS 1407T=LMG 24690T=CIP 109850T) and Ensifer garamanticus sp. nov. (type strain ORS 1400T=LMG 24692T=CIP 109916T) are proposed. The cluster B strains were assigned to Ensifer adhaerens genomovar A.

A group of Sesbania cannabina rhizobia belonging to four recA genotypes of a novel group was further characterized in comparison with the related Ensifer species. They showed 98.2 to 99.9 % similarities among themselves and 92.9 to 93.3 % similarities with the most related strain Ensifer sojae CCBAU 05684 T in multilocus sequence analysis of recA, atpD and glnII. The genome average nucleotide identity values between representative strain YIC4027 T and the type strains of its closely related species were 81.6 to 88.9 %. Identical symbiotic gene (nodA, nodC and nifH) sequences highly similar with those in other Sesbania-nodulating strains (Rhizobium sp. SIN-1, Neorhizobium huautlense S02 T , Ensifer saheli ORS609 T and Rhizobium sp. IRBG74) were detected. The representative strain YIC4027 T could form effective nodules on its original host Sesbania cannabina, but not on Sophora flavescens, Trifolium repens, Glycine max, Glycyrrhiza uralensis, Phaseolus vulgaris or Medicago sativa. The use of lactulose as sole carbon source, possession of C 13 : 0 2-OH, C 13 : 1 at 12-13, C 15 : 1 iso !9c, C 17 : 0 anteiso and C 18 : 0 iso and absence of C 14 : 0 anteiso, C 15 : 0 anteiso and C 18 : 0 3-OH in fatty acids distinguished the strain YIC4027 T from the type strains of its closely related species. Based on all the analyses mentioned above, we propose a novel species Ensifer alkalisoli sp. nov. and designate YIC4027 T (=HAMBI 3655 T =LMG 29286 T ) as the type strain. The genome size of YIC4027 T is 5.97 Mbp, comprising 5588 predicted genes, and the DNA G+C content is 62.2 mol%.
