EuGI: A novel resource for studying genomic islands to facilitate horizontal gene transfer detection in eukaryotes

tailieu.vn

Keywords: Genomic island, Horizontal gene transfer, SWGIS v2.0, Eukaryotes, Comparative genomics, Software tools. Horizontal gene transfer (HGT) allows organisms to rapidly adapt to fluctuating environments and different ecological pressures or oppor- tunities [3, 4]. The acquisition of GIs have also been shown to be central in the evolution of pathogenesis in virulent microbes [6]..

Genomic erosion and extensive horizontal gene transfer in gut-associated Acetobacteraceae

tailieu.vn

Horizontal gene transfer, a hallmark of the gut as an ecological niche [30], has had a profound impact on the content and functional potential of both AAB2 strains.. Approximately 15% (Table 1) of the genome of each AAB strain was acquired via horizontal transfer from closely related taxa, as well as across phyla and king- doms (Fig.

Therefore, the data present epidemiological evidence for the horizontal gene transfer of a transposon structure containing bla VIM-2 , but no evidence for the transfer of a complete identical plasmid between the species [28]. 3 Overview of ARG content in the phylogenetic clusters of bla VIM positive P. Here, the strains P3, P19, P24, P26, P39 (cluster 5A II) contained a bla VIM-2 , aadA1 and aph3-Ib gene in addition to the other ARGs of that cluster.

Genus level analysis of PKS-NRPS and NRPS-PKS hybrids reveals their origin in Aspergilli

tailieu.vn

Homologous hybrids are present in all sections which suggests frequent horizontal gene transfer between genera and a finite number of hybrids in fungi.. Conclusion: Phylogenetic distances between hybrids provide us with evidence for their evolution: Large inter-group distances indicate multiple independent events leading to the generation of hybrids, while short intra-group distances of hybrids from different taxonomic sections indicate frequent horizontal gene transfer.

Sequencing of five poultry strains elucidates phylogenetic relationships and divergence in virulence genes in Morganella morganii

tailieu.vn

Through comparative genomics ana- lysis, we pinpointed 26 virulence genes as specific to the subspecies sibonii and showed that some of them might have originated by horizontal gene transfer from closely related Morganellaceae species.

Mining biosynthetic gene clusters in Virgibacillus genomes

tailieu.vn

Since horizontal gene transfer is considered central to microbes’ ability to adapt to an ecological niche, we also predicted the genomic islands (GIs) in the analyzed genomes to increase our understanding as to how the three Virgibacillus strains have potentially acquired gen- omic elements adding to their biosynthetic capacity.. Bac332 has the highest number of GIs with a total of 434,257 bp of DNA (21 GIs harboring 559 genes), equiva- lent to 9% of the genome size.

PacBio genome sequencing reveals new insights into the genomic organisation of the multi-copy ToxB gene of the wheat fungal pathogen Pyrenophora tritici-repentis

The inverse gene-for-gene interactions between host plants and necrotrophic fungal pathogen typically in- volve pathogen effectors, which interact with a compat- ible locus in the host leading to toxin sensitivity and disease susceptibility.. In the Ptr genome, ToxA is a single locus gene, the re- sult of a horizontal gene transfer from another fungal pathogen species [9].

The invasive MED/Q Bemisia tabaci genome: A tale of gene loss and gene gain

We used a phylogenetic approach to test the hypothesis that horizontal gene transfer (HGT) was involved in the gain of certain amino acid biosynthetic pathways.

Virulence factors and antibiotic-resistance genes (ARGs) can also be vertically transferred and spread via horizon- tal gene transfer (HGT) through mobile genetic ele- ments (MGEs) such as plasmids, bacteriophages, transposons, integrative and conjugative elements (ICEs), and genetic islands (GIs) [33].

Gene Transfer Techniques in Plants by Nicole Jovanovic. Well, you might be able to with today’s transgenic. Today’s transgenic technology involves gene transfer in plants, as well as bacteria and animals.. First of all, to do genetic engineering, you need a genetic vector. A genetic vector is something used to. transport genes into the new host. There are a few things a vector needs to be a good vector.

Horizontal gene transfer plays a major role in the pathological convergence of Xanthomonas lineages on common bean

tailieu.vn

In particu- lar, all strains from the four genetic lineages display an allele of the tal23A gene, suggesting that this gene is im- portant for Xanthomonas adaptation to common bean.. In order to obtain genomic data representative of the di- versity of Xanthomonas strains responsible for CBB, we produced whole genome sequences for 17 strains from the four genetic lineages of X. [24], while the largest gene loss (819) was observed at the origin of the Xylella genus.
