) buffer (10 mM Tris-Cl, 0.5 mM EDTA, pH 9.0, Qiagen) on a clean slide, and squashed using a clean slide cover with the aid of a pipette tip. The suspension was collected by adding 20 μl of TE buffer after gently removing the slide cover and leaving the solution on the slide (Pedram, 2017). The DNA sample was stored at −20°C until used as the polymerase chain reaction (PCR) template. The near-full-length sequence of the small subunit ribosomal DNA (SSU rDNA) was amplified using the forward primer 18S4

Molecular Characterization and Phylogeny of Ditylenchus weischeri from Cirsium arvense in the Prairie Provinces of Canada

molecular analysis of many D. weischeri specimens from Canada is presented. Individuals from 41C. arvense or yellow pea grain samples with seeds of C. arvense from the Prairie Provinces were sequenced for the internal transcribed spacer (ITS rDNA), large subunit (LSU) D2D3 28S rDNA, partial segment of small subunit (SSU) 18S rDNA, and the heat shock protein Hsp90 gene. The analysis also included D. weischeri individuals from C. arvense from Russia and garlic with D. dipsaci from the Provinces of Ontario

However, detailed study of fresh females revealed it has three drop-shaped stylet knobs and long PUS, making it typologically similar to the genus Robustodorus, meriting its taxonomic revision, i.e., transferring to it.

Improved 18S small subunit rDNA primers for problematic nematode amplification

The 18S small subunit (SSU) ribosomal DNA sequence is one of the most useful molecular loci for identification and phylogeny reconstruction of agriculturally important nematodes. Various pairs of universal primers have been developed in the past to amplify short and long nematode sequences. However, certain nematode taxa were not readily amplified and/or sequenced with the existing primer tools. Frequently, the center region of a roughly 1,000 nucleotide segment would be lost. Therefore new

Sequence alignment detects a percent of identity up to 88.0% with other Heteroxynematidae species. Phylogenetic analysis showed that the present recorded is a putative sister taxon to A. tetraptera recorded in a previous study. The SSU rDNA sequence has been deposited in the GenBank under the accession no. MG019400.
