Nodulation and nitrogen fixation genes of Mesorhizobium loti are encoded on the chromosome of the bacterium. Nevertheless, there is strong evidence that these genes can be transferred from an inoculant strain to nonsymbiotic mesorhizobia in the field environment. Here we report that the chromosomal symbiotic element of M. loti strain ICMP3153 is transmissible in laboratory matings to at least t...
The 3.31-Mb genome sequence of the intracellular pathogen and potential bioterrorism agent, Brucella suis, was determined. Comparison of B. suis with Brucella melitensis has defined a finite set of differences that could be responsible for the differences in virulence and host preference between these organisms, and indicates that phage have played a significant role in their divergence. Analys...
NodMl-V(C(18:1), Me, Cb, AcFuc) is a major component of lipo-chitin oligosaccharides (LCOs), or Nod factors, produced by Mesorhizobium loti. The presence of a 4-O-acetylated fucosyl residue (AcFuc) at the reducing end has been thought to be essential for symbiotic interactions with the compatible host plant, Lotus japonicus. We generated an M. loti mutant in which the nolL gene is disrupted; no...
We recently isolated and discovered new Bradyrhizobiaceae microbes from the cryopreserved culture broth of blood samples from 3 patients with poorly defined illnesses using modified SP4 media and culture conditions coupled with genomic sequencing. Using a similar protocol, we studied a previously cryopreserved culture broth of blood sample from a patient who had succumbed to an acute onset of f...
Mesorhizobium loti strain R88B was isolated in 1993 in the Rocklands range in Otago, New Zealand from a Lotus corniculatus root nodule. R88B is an aerobic, Gram-negative, non-spore-forming rod. This report reveals the genome of M. loti strain R88B contains a single scaffold of size 7,195,110 bp which encodes 6,950 protein-coding genes and 66 RNA-only encoding genes. This genome does not harbor ...
Legumes have an intrinsic capacity to accommodate both symbiotic and endophytic bacteria within root nodules. For the symbionts, a complex genetic mechanism that allows mutual recognition and plant infection has emerged from genetic studies under axenic conditions. In contrast, little is known about the mechanisms controlling the endophytic infection. Here we investigate the contribution of bot...
Single-locus sporophytic self-incompatibility inhibits inbreeding in many members of the mustard family (Brassicaceae). To investigate the genetics of self-incompatibility in the wild mustard Leavenworthia alabamica, diallel crosses were conducted between full siblings. Patterns of incompatibility were consistent with the action of single-locus sporophytic self-incompatibility. DNA sequences re...
In this study, Illumina MiSeq was used to investigate the microbial diversity ofwine grapes and soil from three vineyards indifferent localities on eastern foothills of Helan Mountain in Ningxia, China. The results 26 samples showed thatthere were 4 fungal phyla with 1107 operational taxonomic units (OTUs) 11 bacterial 4630 OTUs. At genus level, dominant fungi included Aspergillus, Alternaria, ...
Pyroligneous acid (PA) is often used in agriculture as a plant growth and yield enhancer. However, the influence of PA application on soil microorganisms not studied. Therefore, this study, we investigated effect (0.01–5% w/w soil) microbial diversity two different soils. At end eight weeks incubation, community dynamics were determined by Illumina-MiSeq sequencing 16S rRNA gene amplicons. The ...
