Root-knot nematodes (RKNs; spp.) are among the most widespread and damaging plant-parasitic nematodes known. Although is the most prevalent RKN species, other species, including , , and , have recently been detected in multiple Georgia, United States, vegetable fields.

The locus contributes to the strong and effective SCN resistance, with resistance levels predominantly governed by copy number variations (CNVs) and, to lesser extent, sequence variations.

- Root-lesion nematodes, specifically a new species called Pratylenchus dakotaensis, have been found in North Dakota soybean fields, posing a threat to crop yields.
- A new recombinase polymerase amplification (RPA) assay was created to quickly detect this nematode in soil samples, achieving results in just 20 minutes at a temperature of 39.5°C.
- The RPA assay demonstrated high specificity by accurately amplifying DNA from P. dakotaensis without affecting other nematode species, making it a valuable tool for effective nematode management in agriculture.
Two greenhouse experiments were conducted with the new species of root-lesion nematode, , discovered in North Dakota, USA in 2017 and named in 2021. Experiment 1 was conducted to ascertain resistance levels of soybean ( [L.] Merr.

Species-specific primers, targeting the internal transcribed spacer region of ribosomal DNA, were designed to be used in both conventional and quantitative real-time PCR assays for identification of . The specificity of the primers was evaluated in silico analysis and laboratory PCR experiments.

Because host resistance is the primary strategy used to control SCN, knowledge of SCN virulence phenotypes (HG types) is necessary for choosing sources of resistance for SCN management. To characterize SCN virulence phenotypes in North Dakota, a total of 419 soybean fields across 22 counties were sampled during 2015, 2016, and 2017.

- Root-lesion nematodes of the genus Filipjev are significant pests affecting soybean crops, alongside other nematodes like soybean cyst and root-knot nematodes.
- In a study conducted in 2015 and 2016, soil samples from a soybean field in North Dakota were analyzed, revealing the presence of different life stages of these nematodes.
- The research confirmed the existence of a new, unnamed species of root-lesion nematode based on both morphological characteristics and molecular analysis, distinguishing it from closely related species.
