1. Genome-wide identification and characterization of R2R3-MYB genes in Medicago truncatula
Abstract MYB is a large family of plant transcription factors. Its function has been identified in several plants, while there are few reports in Medicago truncatula. In this study, we used RNA-seq data to analyze and identify R2R3-MYB genes in the genome of Medicago truncatula. Phylogenetic analysis classified 150 MtMYB genes into 21 subfamilies with homolo

2. Isolation, Characterization and Symbiotic Efficiency of Nitrogen-Fixing and Heavy Metal-Tolerant Bacteria from a Coalmine Wasteland
ABSTRACT: Areas affected by coal mining can be recovered by revegetation with leguminous plants associated with nitrogen-fixing bacteria. This study addressed the isolation and characterization of native nitrogen-fixing bacteria from coalmine wasteland under different vegetation restoration approaches using Macroptilium atropurpureum (DC) Urb and Vicia sativ

3. Draft genome sequence of Bradyrhizobium manausense strain BR 3351T, an effective symbiont isolated from Amazon rainforest
ABSTRACT The strain BR 3351T (Bradyrhizobium manausense) was obtained from nodules of cowpea (Vigna unguiculata L. Walp) growing in soil collected from Amazon rainforest. Furthermore, it was observed that the strain has high capacity to fix nitrogen symbiotically in symbioses with cowpea. We report here the draft genome sequence of strain BR 3351T. The infor

4. Bradyrhizobium elkanii nod regulon: insights through genomic analysis
Abstract A successful symbiotic relationship between soybean [Glycine max (L.) Merr.] and Bradyrhizobium species requires expression of the bacterial structural nod genes that encode for the synthesis of lipochitooligosaccharide nodulation signal molecules, known as Nod factors (NFs). Bradyrhizobium diazoefficiens USDA 110 possesses a wide nodulation gene re

5. Genome sequence of Bradyrhizobium embrapense strain CNPSo 2833T, isolated from a root nodule of Desmodium heterocarpon
Abstract Bradyrhizobium embrapense CNPSo 2833T is a nitrogen-fixing symbiont of the legume pasture Desmodium. Its draft genome contains 8,267,832 bp and 7876 CDSs. The symbiotic island includes nodulation and nitrogen fixation genes resembling the operon organization of B. japonicum. Several CDSs related to secretion proteins and stress tolerance were also i

7. Inicio da nodulacao em sete cultivares de feijoeiro inoculadas com duas estirpes de rhizobium.
A nodulacao precoce e manutencao de nodulos efetivos durante o florescimento do feijoeiro (Phaseolus vulgaris L.) podem favorecer a fixacao biologica do N2 nessa cultura. Dessa forma, procurou-se identificar o potencial de inducao dos genes da nodulacao e o potencial de atracao simbiotica das raizes de sete cultivares de feijoeiro inoculadas com duas estirpe

9. Two gene clusters of Rhizobium meliloti code for early essential nodulation functions and a third influences nodulation efficiency.
A pLAFR1 cosmid clone (pPP346) carrying the nodulation region of the symbiotic plasmid pRme41b was isolated from a gene library of Rhizobium meliloti 41 by direct complementation of a Nod- deletion mutant of R. meliloti. Agrobacterium tumefaciens and Rhizobium species containing pPP346 were able to form ineffective nodules on alfalfa. The 24-kilobase insert

10. Novel organization of the common nodulation genes in Rhizobium leguminosarum bv. phaseoli strains.
Nodulation by Rhizobium, Bradyrhizobium, and Azorhizobium species in the roots of legumes and nonlegumes requires the proper expression of plant genes and of both common and specific bacterial nodulation genes. The common nodABC genes form an operon or are physically mapped together in all species studied thus far. Rhizobium leguminosarum bv. phaseoli strain

11. Conserved nodulation genes from the non-legume symbiont Bradyrhizobium sp. (Parasponia).
A nodulation locus from the broad-host-range, non-legume symbiont Bradyrhizobium sp. (Parasponia) strain ANU289, has been identified by hybridisation to cloned Rhizobium trifolii nodulation (nod) genes. Transfer of cloned ANU289 nod genes to R.trifolii nodulation-deficient mutants showed that the locus contains a functional homologue of the R. trifolii nodD

12. Rhizobium symbiotic genes required for nodulation of legume and nonlegume hosts
Parasponia, a woody member of the elm family, is the only nonlegume genus whose members are known to form an effective nitrogen-fixing symbiosis with Bradyrhizobium or Rhizobium species. The Bradyrhizobium strain Rp501, isolated from Parasponia nodules, also nodulates the legumes siratro (Macroptilium atropurpureum) and cowpea (Vigna unguiculata). To test wh
