Abstract Root‐lesion nematodes of the genus Pratylenchus are migratory endoparasites with worldwide economic impact on several important crops including potato, where certain species like P. penetrans , neglectus and scribneri reduce yield quality potato tubers. Morphological identification spp. is challenging, recent advancements in molecular techniques provide robust rapid diagnostics to differentiate without need specialist skills. However, fact that not available for all means there...

The Xiphinema americanum -group is a large species complex containing more than 50 nematode species. They are economically important because they vectors of nepoviruses. differentiation X. problematic the share similar morphological characters. In present study we collected samples from different locations in USA, Italy and Russia. Six valid species, s. str. , brevicolle californicum pachtaicum rivesi simile four unidentified putative were characterised by morphology sequencing D2-D3 28S...

Abstract Nematodes, commonly called roundworms, represent one of the largest phyla animals. Plant‐parasitic nematodes cause significant economic losses in major crops worldwide, and cyst ( Heterodera spp. Globodera spp.) are among most damaging species. This review focuses on three main species, pallida , rostochiensis ellingtonae collectively known as potato (PCNs). G. occurring species potato‐growing areas considered to have originated from Andes region South America introduced then Europe...

Abstract Chromosomal structural rearrangements consist of anomalies in genomic architecture that may or not be associated with genetic material gain and loss. Evaluating the precise breakpoint is crucial from a diagnostic point view, highlighting possible gene disruption addressing to appropriate genotype–phenotype association. Structural can either occur randomly within genome present recurrence, mainly due peculiar features surrounding regions. We report about three non-related...

Summary Robust and accurate identification of root-lesion nematodes ( Pratylenchus spp.) is an essential step for determining their potential threat to crop yields and, consequently, development efficient agronomic management strategy. It recognised that DNA-based techniques provide rapid a range plant-parasitic including spp. Efficient repeatable DNA extraction central molecular methodologies. Here, six common protocols were compared evaluate efficiency obtain quality samples penetrans ....

Summary Pratylenchus crenatus , P. neglectus penetrans and thornei are globally the most commonly occurring species of root-lesion nematodes (RLN). Correct identification quantification these is important for strategic management interventions such as rotation choice nematicide use. A real-time quantitative PCR can provide a fast reliable alternative to morphological identification, which requires significant taxonomic experience. TaqMan hydrolysis probe method based on 28S rDNA D2-D3...

Darmera peltata (umbrella plant or Indian rhubarb) is a perennial that prefers moist soil with partial to full shade. It has thick rhizome from which leaves emerge directly petiole and wide peltate lamina attaching centrally, forming leaf cup (Wunnenberg et al., 2021). In the UK, it grown as an ornamental plant. No report of foliar nematode infestation on D. had been recorded prior this study. An investigation by APHA Plant Health Seed Inspector found exhibiting symptoms typical...
