Comparison of genetic differences between Streptomyces scabies and turgidiscabies strains

ABSTRACT: Bacteria isolated from potato scab lesions in Finland or northern Sweden were analyzed using microarrays, PCR, and sequencing. Data indicate wide genetic variability in pathogenicity islands among S.turgidiscabies and S.scabies strains.

Comparison of genetic differences between Streptomyces scabies and turgidiscabies strains

Project description:Bacteria isolated from potato scab lesions in Finland or northern Sweden were analyzed using microarrays, PCR, and sequencing. Data indicate wide genetic variability in pathogenicity islands among S.turgidiscabies and S.scabies strains. Thirteen Streptomyces scabies and turgidiscabies strains from two different growings, Streptomyces reticulisabiei reference strain DSM41804 and Streptomyces scabies reference strain ATCC49173 were hybridized. Data were analyzed in single channel mode.

Microarray-based species identification of Streptomyces spp. isolated from potato scab lesions in Norway

Project description:28 Streptomyces strains isolated from common scab lesions of potato tubers from a wide geographic range in Norway, were selected for microarray analysis. The selected strains were subjected to species identification by microarray, 16S phylogenetic analysis and PCR; and microarray-based comparative genome analysis. To our knowledge, this is the first report of S. turgidiscabies and S. europaeiscabiei in Norway. 28 Norwegian Streptomyces strains were hybridized in duplicates, one S.turgidiscabies strain (St32) and one S.scabies strain (ATCC49173) were hybridized in 4 replicates. Two out of 64 hybridizations failed (replicate hybridizations of Norwegian strains 33 and 44), for a total of 62 samples. Normalization was based on log-ratios against reference strain.

Mutation Mapping of 31 Streptococcus suis strains

Project description:Identification of Genes and Genomic Islands Correlated with High Pathogenicity through Tilling Microarray-Based Comparative Genomics in S. suis. Streptococcus suis is an important zoonotic pathogen that can cause meningitis and sepsis in both pigs and humans. S. suis isolates have been categorized into groups of different levels of pathogenicity, with sequence type (ST) ST1 clonal complex strains having a higher degree of virulence than other STs. However, the genetic basis of the differences in pathogenicity is still poorly understood. In this study, a comprehensive genomic comparison of 31 S. suis strains from different clinical sources with the genome sequence of the high pathogenicity (HP) strain GZ1 was conducted using NimbleGen’s tilling microarray platform.

Multi-omics reveals mechanisms of potato resistance to powdery scab

Project description:The potato powdery scab agent Spongospora subterranea causes damage on the skin of tubers and induces root gall formation, precipitating considerable yield and quality losses. Currently, there are no effective chemical treatments for the control of powdery scabs. Understanding the inducible defence responses in roots of potato plants in the resistant and susceptible host environment, particularly during colonisation of the root by S. subterranea is required for the breeding of novel resistant cultivars. Here, we integrated transcriptomics, proteomics and metabolomics datasets to uncover the mechanisms underlying of the potato resistance to powdery scab. This multi-omics approach identified upregulation of glutathione metabolism at the levels of RNA, protein and metabolite in the resistant cultivar but not in the susceptible cultivar. Upregulation of the lignin metabolic process was also specific to in the resistant cultivar at the transcriptome level. In addition, Tthe inositol phosphate pathway was differentially expressed between two cultivars in response to S. subterranea infection, where it was upregulated in the susceptible cultivar but downregulated in the resistant cultivar. We provide, for the first time, large-scale multi-omics data of Spongospora-potato interaction, thereby suggesting the signaling role of glutathione metabolism in the potato resistance against powdery scab

An Arabidopsis Mutant Resistant to Thaxtomin A, a Cellulose Synthesis Inhibitor from Streptomyces Sp

Project description:Thaxtomin A is a phytotoxin produced by Streptomyces scabies and other Streptomyces species, the causative agents of common scab disease in potato and other taproot crops. At nanomolar concentrations, thaxtomin causes dramatic cell swelling, reduced seedling growth, and inhibition of cellulose synthesis in Arabidopsis. We identified a mutant of Arabidopsis, designated txr1, that exhibits increased resistance to thaxtomin as a result of a decrease in the rate of toxin uptake. The TXR1 gene was identified by map-based cloning and found to encode a novel, small protein with no apparent motifs or organelle-targeting signals. The protein, which has homologs in all fully sequenced eukaryotic genomes, is expressed in all tissues and during all developmental stages analyzed. Microarray transcript profiling of some 14,300 genes revealed two stomatin-like genes that were expressed differentially in the txr1 mutant and the wild type. We propose that TXR1 is a regulator of a transport mechanism A genetic modification design type is where an organism(s) has had genetic material removed, rearranged, mutagenized or added, such as knock out.
