Complete genome sequence of biocontrol strain Pseudomonas fluorescens LBUM223.

Pseudomonas fluorescens LBUM223 is a plant growth-promoting rhizobacterium (PGPR) with biocontrol activity against various plant pathogens. It produces the antimicrobial metabolite phenazine-1-carboxylic acid, which is involved in the biocontrol of Streptomyces scabies, the causal agent of common scab of potato. Here, we report the complete genome sequence of P. fluorescens LBUM223. Copyright © 2015 Roquigny et al.

Complete genome sequence of Paenibacillus beijingensis 7188(T) (=DSM 24997(T)), a novel rhizobacterium from jujube garden soil.

We present here the complete genome sequence of a novel species Paenibacillus beijingensis 7188(T) (=DSM 24997(T)) from jujube rhizosphere soil that consists of one circular chromosome of 5,749,967bp with a GC content of 52.5%. On the significance of first genome information in this species, the genome sequence of strain 7188(T) will provide a better comprehension of Paenibacillus species for the practical uses as a biofertilizer in agriculture.

Complete genome sequence of the rhizobacterium Pseudomonas trivialis strain IHBB745 with multiple plant growth-promoting activities and tolerance to desiccation and alkalinity

The complete genome sequence of 6.45 Mb is reported here for Pseudomonas trivialis strain IHBB745 (MTCC 5336), which is an efficient, stress-tolerant, and broad-spectrum plant growth-promoting rhizobacterium. The gene-coding clusters predicted the genes for phosphate solubilization, siderophore production, 1-aminocyclopropane-1-carboxylate (ACC) deaminase activity, indole-3-acetic acid (IAA) production, and stress response.

High quality draft genome sequence of the type strain of Pseudomonas lutea OK2(T), a phosphate-solubilizing rhizospheric bacterium.

Pseudomonas lutea OK2(T) (=LMG 21974(T), CECT 5822(T)) is the type strain of the species and was isolated from the rhizosphere of grass growing in Spain in 2003 based on its phosphate-solubilizing capacity. In order to identify the functional significance of phosphate solubilization in Pseudomonas Plant growth promoting rhizobacteria, we describe here the phenotypic characteristics of strain OK2(T) along with its high-quality draft genome sequence, its annotation, and analysis. The genome is comprised of 5,647,497 bp with 60.15 % G?+?C content. The sequence includes 4,846 protein-coding genes and 95 RNA genes.

Genomic studies of nitrogen-fixing rhizobial strains from Phaseolus vulgaris seeds and nodules.

Rhizobia are soil bacteria that establish symbiotic relationships with legumes and fix nitrogen in root nodules. We recently reported that several nitrogen-fixing rhizobial strains, belonging to Rhizobium phaseoli, R. trifolii, R. grahamii and Sinorhizobium americanum, were able to colonize Phaseolus vulgaris (common bean) seeds. To gain further insight into the traits that support this ability, we analyzed the genomic sequences and proteomes of R. phaseoli (CCGM1) and S. americanum (CCGM7) strains from seeds and compared them with those of the closely related strains CIAT652 and CFNEI73, respectively, isolated only from nodules.In a fine structural study of the S. americanum genomes, the chromosomes, megaplasmids and symbiotic plasmids were highly conserved and syntenic, with the exception of the smaller plasmid, which appeared unrelated. The symbiotic tract of CCGM7 appeared more disperse, possibly due to the action of transposases. The chromosomes of seed strains had less transposases and strain-specific genes. The seed strains CCGM1 and CCGM7 shared about half of their genomes with their closest strains (3353 and 3472 orthologs respectively), but a large fraction of the rest also had homology with other rhizobia. They contained 315 and 204 strain-specific genes, respectively, particularly abundant in the functions of transcription, motility, energy generation and cofactor biosynthesis. The proteomes of seed and nodule strains were obtained and showed a particular profile for each of the strains. About 82 % of the proteins in the comparisons appeared similar. Forty of the most abundant proteins in each strain were identified; these proteins in seed strains were involved in stress responses and coenzyme and cofactor biosynthesis and in the nodule strains mainly in central processes. Only 3 % of the abundant proteins had hypothetical functions.Functions that were enriched in the genomes and proteomes of seed strains possibly participate in the successful occupancy of the new niche. The genome of the strains had features possibly related to their presence in the seeds. This study helps to understand traits of rhizobia involved in seed adaptation.
