Draft genome sequence of Bradyrhizobium manausense strain BR 3351T, an effective symbiont isolated from Amazon rainforest BJM
Simões-Araújo,Jean Luiz; Rumjanek,Norma Gouvêa; Xavier,Gustavo Ribeiro; Zilli,Jerri Édson.
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 information presented will be important for comparative analysis of nodulation and nitrogen fixation for diazotrophic bacteria. A draft genome with 9,145,311 bp and 62.9% of GC content was assembled in 127 scaffolds using 100 bp pair-end Illumina MiSeq system. The RAST annotation identified 8603 coding sequences, 51 RNAs genes, classified in 504 subsystems.

Draft genome sequence of Bradyrhizobium sp. strain BR 3262, an effective microsymbiont recommended for cowpea inoculation in Brazil BJM
Simões-Araújo,Jean Luiz; Leite,Jakson; Marie Rouws,Luc Felicianus; Passos,Samuel Ribeiro; Xavier,Gustavo Ribeiro; Rumjanek,Norma Gouvêa; Zilli,Jerri Édson.
Abstract The strain BR 3262 was isolated from nodule of cowpea (Vigna unguiculata L. Walp) growing in soil of the Atlantic Forest area in Brazil and it is reported as an efficient nitrogen fixing bacterium associated to cowpea. Firstly, this strain was assigned as Bradyrhizobium elkanii, however, recently a more detailed genetic and molecular characterization has indicated it could be a Bradyrhizobium pachyrhizi species. We report here the draft genome sequence of B. pachyrhizi strain BR 3262, an elite bacterium used as inoculant for cowpea. The whole genome with 116 scaffolds, 8,965,178 bp and 63.8% of C+G content for BR 3262 was obtained using Illumina MiSeq sequencing technology. Annotation was added by the RAST prokaryotic genome annotation service and...

Draft genome sequence of Bradyrhizobium sp. strain BR 3267, an elite strain recommended for cowpea inoculation in Brazil BJM
Simões-Araújo,Jean Luiz; Leite,Jakson; Passos,Samuel Ribeiro; Xavier,Gustavo Ribeiro; Rumjanek,Norma Gouvêa; Zilli,Jerri Édson.
Abstract The strain BR 3267 is a nitrogen-fixing symbiotic bacteria isolated from soil of semi-arid area of Brazilian Northeast using cowpea as the trap plant. This strain is used as commercial inoculant for cowpea and presents high efficient in nitrogen fixation as consequence of its adaptation potential to semi-arid conditions. We report here the draft genome sequence of Bradyrhizobium sp. strain BR 3267, an elite bacterium used as inoculant for cowpea. Whole genome sequencing of BR 3267 using Illumina MiSeq sequencing technology has 55 scaffolds with a total genome size of 7,904,309 bp and C+G 63%. Annotation was added by the RAST prokaryotic genome annotation service and has shown 7314 coding sequences and 52 RNA genes.

Draft genome sequence of Paraburkholderia tropica Ppe8 strain, a sugarcane endophytic diazotrophic bacterium BJM
Silva,Paula Renata Alves da; Simões-Araújo,Jean Luiz; Vidal,Márcia Soares; Cruz,Leonardo Magalhães; Souza,Emanuel Maltempi de; Baldani,José Ivo.
Abstract Paraburkholderia tropica (syn Burkholderia tropica) are nitrogen-fixing bacteria commonly found in sugarcane. The Paraburkholderia tropica strain Ppe8 is part of the sugarcane inoculant consortium that has a beneficial effect on yield. Here, we report a draft genome sequence of this strain elucidating the mechanisms involved in its interaction mainly with Poaceae. A genome size of approximately 8.75 Mb containing 7844 protein coding genes distributed in 526 subsystems was de novo assembled with ABySS and annotated by RAST. Genes related to the nitrogen fixation process, the secretion systems (I, II, III, IV, and VI), and related to a variety of metabolic traits, such as metabolism of carbohydrates, amino acids, vitamins, and proteins, were...

Expressão gênica induzida por estresses abióticos em nódulos de feijão-caupi PAB
Silva,Helder Anderson Pinto da; Galisa,Péricles de Souza; Oliveira,Roselaine Sanches da Silva; Vidal,Marcia Soares; Simões-Araújo,Jean Luiz.
O objetivo deste trabalho foi avaliar o efeito isolado ou simultâneo dos estresses hídrico e térmico na expressão gênica em nódulos de feijão-caupi. A bactéria Bradyrhizobium japonicum (estirpe BR 3267) foi inoculada em sementes de feijão-caupi da cultivar IPA 206 e, 35 dias após a germinação, as plantas foram submetidas a diferentes regimes de disponibilidade hídrica e a estresse térmico, em casa de vegetação. Para a identificação dos genes diferencialmente expressos, foi utilizada a técnica de cDNA-AFLP, tendo-se isolado 67 fragmentos derivados de transcritos (FDTs) diferencialmente expressos. Após o sequenciamento dos FDTs e das análises de similaridade, com uso do programa Blastx, foram identificados 14 genes diferencialmente expressos envolvidos em...

Genomic identification and characterization of the elite strains Bradyrhizobium yuanmingense BR 3267 and Bradyrhizobium pachyrhizi BR 3262 recommended for cowpea inoculation in Brazil BJM
Leite,Jakson; Passos,Samuel Ribeiro; Simões-Araújo,Jean Luiz; Rumjanek,Norma Gouvêa; Xavier,Gustavo Ribeiro; Zilli,Jerri Édson.
ABSTRACT The leguminous inoculation with nodule-inducing bacteria that perform biological nitrogen fixation is a good example of an “eco-friendly agricultural practice”. Bradyrhizobium strains BR 3267 and BR 3262 are recommended for cowpea (Vigna unguiculata) inoculation in Brazil and showed remarkable responses; nevertheless neither strain was characterized at species level, which is our goal in the present work using a polyphasic approach. The strains presented the typical phenotype of Bradyrhizobium with a slow growth and a white colony on yeast extract-mannitol medium. Strain BR 3267 was more versatile in its use of carbon sources compared to BR 3262. The fatty acid composition of BR 3267 was similar to the type strain of Bradyrhizobium yuanmingense;...

Small heat shock proteins genes are differentially expressed in distinct varieties of common bean Braz. J. Plant Physiol.
Simões-Araújo,Jean Luiz; Rumjanek,Norma Gouvêa; Margis-Pinheiro,Márcia.
Plants respond to temperature stress by synthesizing a set of heat shock proteins (HSPs), which may be responsible for the acquisition of thermotolerance. In this study, the induction of small HSPs (sHSPs) in eight common bean varieties was evaluated by Northern blot analysis using the W HSP 16.9 cDNA as heterologous probe. Cowpea was used, as a positive control since this plant, as opposed to common bean, is known to grow well under high temperature regimes such as that found in the Brazilian semi-arid region. After the growth period, the plants were submitted to two h of heat shock at 40 ºC. All varieties tested were able to induce sHSP mRNAs that hybridized with W HSP 16.9 probe. However, significant kinetic differences were found when comparing...

Unravelling MADS-box gene family in Eucalyptus spp.: a starting point to an understanding of their developmental role in trees Genet. Mol. Biol.
Dias,Beatriz Fonseca de Oliveira; Simões-Araújo,Jean Luiz; Russo,Claudia A.M.; Margis,Rogério; Alves-Ferreira,Márcio.
MADS-box genes encode a family of transcription factors which control diverse developmental processes in flowering plants ranging from root to flower and fruit development. Members of the MADS-box gene family share a highly conserved sequence of approximately 180 nucleotides that encodes a DNA-binding domain. We used bioinformatics tools to investigate the information generated by the Eucalyptus Expressed Sequence Tag (FORESTs) genome project in order to identify and annotate MADS-box genes. The comparative phylogenetic analysis of the Eucalyptus MADS-box genes with Arabidopsis homologues allowed us to group them into one of the well-known subfamilies. Trends in gene expression of these putative Eucalyptus MADS-box genes were investigated by hierarchical...
