Phylogenetic Analysis of Protein Sequences

Check if the same lab product or an alternative is used in the 5 most similar protocols
Sequences were obtained by using pblastp suite https://blast.ncbi.nlm.nih.gov/Blast.cgi or directly from http://flybase.org and http://www.wormbase.org. Alignment was performed by using the alignment tool of CLC Main Workbench 7.9.1 (Qiagen Bioinformatics). Parameters were kept as default (gap open cost: 10, gap extension cost: 1, end gap cost: as any other). We tested for the appropriate model by using MEGA6.06 [20 (link)]. A Maximum Likelihood tree was constructed via PhyML3.2 [21 (link)] by using the model LG+G ([22 (link)], gamma shape parameter: 0.628) and Bootstrap branch support (100 replicates). The final tree was modified by using CLC Main Workbench 7.9.1 (Qiagen Bioinformatics) and Affinity Designer 1.6.0 (Serif).

Mapping Haploblock Regions in Wheat Lr22a

Check if the same lab product or an alternative is used in the 5 most similar protocols
For the identification of the haploblock region, we mapped previously generated Illumina reads of CH Campala Lr22a and CH Campala [32 (link)] to the Chinese Spring pseudomolecule using CLC Main Workbench 7 (Qiagen) with standard parameters. The mapped read file was later used for the variant call analysis by CLC Main Workbench 7 (Qiagen) using standard parameters. SNP density was calculated in sliding windows of 2.5 Mb. To verify the haploblock c region we designed a PCR probe (forward primer GCCACGAGCGTGGTCGTG, reverse primer CCTTCATAGCTCCGTAGAAG) spanning the left border of the haploblock c of CH Campala Lr22a. The PCR amplification was performed in 20 μl reaction mixture containing 65 ng of genomic DNA, 1 μl of 2.5 mM dNTP’s, 1 μl of 10 μM of each primer and 0.25 units of Sigma Taq polymerase at 60 °C annealing temperature for 35 cycles. The cycling parameters used were pre-denaturation at 95 °C for 4 min, which was followed by 35 cycles of 95 °C for 30 s, annealing at 60 °C for 30 s, 72 °C for 2 min and a final extension at 72 °C for 10 min. The PCR products were separated on 1.0% agarose gels.

Bioinformatic Analysis of Grapevine Terpene Synthases

Check if the same lab product or an alternative is used in the 5 most similar protocols
Sequence analyses were performed using CLC Main Workbench 7 (CLC Bio-Qiagen, Aarhus, Denmark). Phased diploid annotations of the VviTPS family [27 (link)] were queried to identify the cluster of proteins most similar to the sequenced isolates. MUSCLE alignments [72 (link),73 (link)] and phylogenetic tree construction were performed as described earlier using CLC Main Workbench 7 (CLC Bio-Qiagen, Aarhus, Denmark). Gene sequence data and Cytoscape network data were retrieved, as per the instructions in reference [27 (link)]. The I′ score [38 (link)] was calculated from BLASTn [62 (link)] scores of isolates queried against all diploid complete VviTPS genes (mRNA sequences) predicted by reference [27 (link)].

Antimicrobial Resistance Genes Detection

Check if the same lab product or an alternative is used in the 5 most similar protocols
DNA was extracted by a standard heat lysis protocol and was analysed by PCR for the presence of antimicrobial resistance genes. Synthesis of primers and custom DNA sequencing were carried out by Microsynth (Balgach, Switzerland). Purification of amplicons was performed using a PCR purification kit (Sigma-Aldrich, Buchs, Switzerland). All presumptive carbapenemase-producers were screened for the presence of blaVIM, blaKPC, blaNDM-1 and blaOXA-48 using previously described primers [15, 16] .
Isolates exhibiting an ESBL phenotype were screened for blaTEM, blaSHV and blaCTX-M genes using previously published primers [17, 18] . Presumptive 16S rRNA methylase-producers were analysed for the presence of armA, rmtA, rmtB, rmtC and rmtD as described previously [19] . All isolates were screened for the presence of the plasmid-mediated colistin resistance gene mcr-1 using primers published recently [20] . Nucleotide sequences were analysed with CLC Main Workbench 7.7 (CLC bio, Aarhus, Denmark). Database searches were performed using the BLASTN program of the National Center for Biotechnology Information (NCBI) (http://www.ncbi.nlm.nih.gov/blast/).

Identification of Bacterial Species via 16S rRNA Sequencing

Check if the same lab product or an alternative is used in the 5 most similar protocols
Identification of bacteria used either Chlamydiae-specific (Draghi et al., 2004 (link); Everett et al., 1999 (link)) or universal bacterial 16S rRNA gene primers (Weisberg et al., 1991 (link)). Positive bands were analysed only when template free negative controls showed no signal. 16S rRNA gene amplicons were sequenced directly from the PCR product or after cloning into Topo vector pCR2.1 (Microsynth, Balgach, Switzerland). The resulting reads were assembled (CLC Main Workbench 7.0.2 (CLC bio, Qiagen) and Sequencher 5.2.4 (Gene Codes Corporation, USA)), compared using blastn against the Genbank database, and analysed using Muscle aligner and PhyML v3 maximum likelihood phylogeny software within Seaview v4 (Gouy et al., 2010 (link)). Representative 16S rRNA gene sequences have been deposited with EMBL under accession numbers: LN612726-LN612730 representing 2013Arg42i, 2013Ark19i, 2013Arg22i, 2013Arg32i, 2012Sar4i, respectively (i indicating Ca. Ichthyocystis sequences).

ESBL Detection in Bacterial Strains

Bacterial strains confirmed as producing ESBLs were further analyzed by PCR. DNA was purified using a standard heat lysis protocol (Sambrook and Russel, 2006 ). Thereafter, five specific primer sets (custom-synthesized by Microsynth, Balgach, Switzerland) were used to screen for β-lactamase-encoding genes belonging to the blaTEM, blaSHV, and blaCTX-M families (Pitout et al., 1998 (link); Geser et al., 2012 (link)).
Resulting amplicons were purified using the GenEluteTM PCR Clean-Up (Sigma–Aldrich, Buchs, Switzerland) according to the manufacturer’s recommendations. Custom-sequencing was performed by Microsynth (Balgach, Switzerland) and the nucleotide- and translated protein-sequences were analyzed with CLC Main Workbench 7.0.2 (CLC bio, Aarhus, Denmark). For database searches the BLASTN program of NCBI 2 was used.

Identification of chlamydial bacteria was carried out using Chlamydiae-specific 16S rRNA gene primers (Everett et al., 1999 (link); Draghi et al., 2004 (link)). Positive bands were analyzed further only when template free negative controls showed no signal. 16S rRNA gene amplicons were cloned into Topo vector pCR2.1 prior to capillary sequencing from both ends (Microsynth, Balgach). The resulting reads were assembled (CLC Main Workbench 7.0.2, CLC bio, Qiagen), compared using blastn against the Genbank database and used to create alignments with reference sequences using Muscle and PhyML v3 within Seaview v4 (Gouy et al., 2010 (link)). Only unique sequences from each sample were included in the analysis. Representative 16S rRNA gene sequences have been deposited with EMBL with the following accession numbers: LN612731-4 representing 2012Sar3_5c, 2013Arg23_1c, 2013Arg33_2c, and 2013Arg14_4c respectively.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
