Rhizobium tumorigenes sp nov a novel plant tumorigenic bacterium isolated from cane gall tumors on thornless blackberry
Scientific Reports, 2018Co-Authors: Nemanja Kuzmanovic, Kornelia Smalla, Sabine Gronow, J PulawskaAbstract:Four plant tumorigenic strains 932, 1019, 1078T and 1081 isolated from cane gall tumors on thornless blackberry (Rubus sp.) were characterized. They shared low sequence identity with related Rhizobium spp. based on comparisons of 16S rRNA gene (≤98%) and housekeeping genes atpD, recA and rpoB (<90%). Phylogenetic analysis indicated that the strains studied represent a novel species within the genus Rhizobium, with Rhizobium tubonense CCBAU 85046T as their closest relative. Furthermore, obtained average nucleotide identity (ANI) and in silico DNA–DNA hybridization (DDH) values calculated for whole-genome sequences of strain 1078T and related Rhizobium spp. confirmed the authenticity of the novel species. The ANI-Blast (ANIb), ANI-MUMmer (ANIm) and in silico DDH values between strain 1078T and most closely related R. tubonense CCBAU 85046T were 76.17%, 84.11% and 21.3%, respectively. The novel species can be distinguished from R. tubonense based on phenotypic and chemotaxonomic properties. Here, we demonstrated that four strains studied represent a novel species of the genus Rhizobium, for which the name Rhizobium tumorigenes sp. nov. is proposed (type strain 1078T = DSM 104880T = CFBP 8567T). R. tumorigenes is a new plant tumorigenic species carrying the tumor-inducing (Ti) plasmid.

Rhizobium skierniewicense sp nov isolated from tumours on chrysanthemum and cherry plum
International Journal of Systematic and Evolutionary Microbiology, 2012Co-Authors: J Pulawska, Anne Willems, P SobiczewskiAbstract:Three isolates of Gram-negative, rod-shaped, non-spore-forming bacteria were recovered from galls on chrysanthemum (Chrysanthemum L.; Ch11T, Ch12) and cherry plum (Prunus cerasifera var. divaricata; AL9.3). All three isolates were able to cause crown galls on various plant species. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the three isolates were probably identical (100% sequence similarity) and closely related to Rhizobium rubi (99.6 %), Rhizobium radiobacter (98.7 %) and Rhizobium larrymoorei (98.1 %). Similar analysis based on the housekeeping genes glnA, gyrB and rpoB also indicated that the novel isolates were identical and closely related to R. rubi . The major cellular fatty acids of strain Ch11T were C18 : 1ω7c (62.1 %), summed feature 2 (comprising C12 : 0 aldehyde, iso-C16 : 1 I and/or C14 : 0 3-OH; 10.8 %), summed feature 3 (comprising C16 : 1ω7c and/or iso-C15 : 0 2-OH; 7.7 %) and C10 : 0 3-OH (7.5 %). However, the DNA–DNA relatedness between Ch11T and R. rubi LMG 156T was only 48 % and, unlike phylogenetically related established Rhizobium species, the novel isolates were able to utilize β-hydroxybutyric acid but not l-fucose. Based on the phylogenetic and phenotypic evidence, the isolates are considered to represent a single novel species of the genus Rhizobium , for which the name Rhizobium skierniewicense sp. nov. is proposed; the type strain is Ch11T ( = LMG 26191T = CFBP 7420T).

Rhizobium calliandrae sp nov Rhizobium mayense sp nov and Rhizobium jaguaris sp nov rhizobial species nodulating the medicinal legume calliandra grandiflora
International Journal of Systematic and Evolutionary Microbiology, 2013Co-Authors: Reiner Rinconrosales, Julio Martinez, Ernesto Ormenoorrillo, Jose M Villalobosescobedo, Marco A Rogel, Esperanza MartinezromeroAbstract: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).

Rhizobium grahamii sp nov from nodules of dalea leporina leucaena leucocephala and clitoria ternatea and Rhizobium mesoamericanum sp nov from nodules of phaseolus vulgaris siratro cowpea and mimosa pudica
International Journal of Systematic and Evolutionary Microbiology, 2012Co-Authors: Aline Lopezlopez, Marco Antonio Rogelhernandez, Isabelle Barois, Angel Isauro Ortiz Ceballos, Julio Martinez, Ernesto Ormenoorrillo, Esperanza MartinezromeroAbstract:Two novel related Rhizobium species, Rhizobium grahamii sp. nov. and Rhizobium mesoamericanum sp. nov., were identified by a polyphasic approach using DNA–DNA hybridization, whole-genome sequencing and phylogenetic and phenotypic characterization including nodulation of Leucaena leucocephala and Phaseolus vulgaris (bean). As similar bacteria were found in the Los Tuxtlas rainforest in Mexico and in Central America, we suggest the existence of a Mesoamerican microbiological corridor. The type strain of Rhizobium grahamii sp. nov. is CCGE 502T ( = ATCC BAA-2124T = CFN 242T = Dal4T = HAMBI 3152T) and that of Rhizobium mesoamericanum sp. nov. is CCGE 501T ( = ATCC BAA-2123T = HAMBI 3151T = CIP 110148T = 1847T).

a revision of Rhizobium frank 1889 with an emended description of the genus and the inclusion of all species of agrobacterium conn 1942 and alloRhizobium undicola de lajudie et al 1998 as new combinations Rhizobium radiobacter r rhizogenes r rubi r u
International Journal of Systematic and Evolutionary Microbiology, 2001Co-Authors: J M Young, Esperanza Martinezromero, L D Kuykendall, A Kerr, Hiroyuki SawadaAbstract:Rhizobium, Agrobacterium and AlloRhizobium are genera within the bacterial family Rhizobiaceae, together with SinoRhizobium. The species of Agrobacterium, Agrobacterium tumefaciens (syn. Agrobacterium radiobacter), Agrobacterium rhizogenes, Agrobacterium rubi and Agrobacterium vitis, together with AlloRhizobium undicola, form a monophyletic group with all Rhizobium species, based on comparative 16S rDNA analyses. Agrobacterium is an artificial genus comprising plant-pathogenic species. The monophyletic nature of Agrobacterium, AlloRhizobium and Rhizobium and their common phenotypic generic circumscription support their amalgamation into a single genus, Rhizobium. Agrobacterium tumefaciens was conserved as the type species of Agrobacterium, but the epithet radiobacter would take precedence as Rhizobium radiobacter in the revised genus. The proposed new combinations are Rhizobium radiobacter, Rhizobium rhizogenes, Rhizobium rubi, Rhizobium undicola and Rhizobium vitis.

Rhizobium impacts on seed productivity quality and protection of pisum sativum upon disease stress caused by didymella pinodes phenotypic proteomic and metabolomic traits
Frontiers in Plant Science, 2017Co-Authors: Nima Ranjbar Sistani, Hanspeter Kaul, Getinet Desalegn, Stefanie WienkoopAbstract:In field peas, ascochyta blight is one of the most common fungal diseases caused by Didymella pinodes. Despite the high diversity of pea cultivars, only little resistance has been developed until to date, still leading to significant losses in grain yield. Rhizobia as plant growth promoting endosymbionts are the main partners for establishment of symbiosis with pea plants. The key role of Rhizobium as an effective nitrogen source for legumes seed quality and quantity improvement is in line with sustainable agriculture and food security programs. Besides these growth promoting effects, Rhizobium symbiosis has been shown to have a priming impact on the plants immune system that enhances resistance against environmental perturbations. This is the first integrative study that investigates the effect of Rhizobium leguminosarum bv. viceae (Rlv) on phenotypic seed quality, quantity and fungal disease in pot grown pea (Pisum sativum) cultivars with two different resistance levels against D. pinodes through metabolomics and proteomics analyses. In addition, the pathogen effects on seed quantity components and quality are assessed at morphological and molecular level. Rhizobium inoculation decreased disease severity by significant reduction of seed infection level. Rhizobium symbiont enhanced yield through increased seed fresh and dry weights based on better seed filling. Rhizobium inoculation also induced changes in seed proteome and metabolome involved in enhanced P. sativum resistance level against D. pinodes. Besides increased redox and cell wall adjustments light is shed on the role of late embryogenesis abundant proteins and metabolites such as the seed triterpenoid Soyasapogenol. The results of this study open new insights into the significance of symbiotic Rhizobium interactions for crop yield, health and seed quality enhancement and reveal new metabolite candidates involved in pathogen resistance.
