The paper investigates whether diversity at the HYP1 locus in potato cyst nematodes arises from developmental editing or sequencing errors, concluding it is due to evolutionary forces.

The paper analyzes global distribution patterns of soil fungal nematode antagonists and identifies environmental drivers influencing their abundance.

The paper assesses global distribution and risk of six tropical root-knot nematodes using species distribution models and thermal-time models, identifying high-risk regions for crop impacts.

The paper investigates patchy potato cyst nematode distribution in fields and identifies microbial communities responsible for local disease suppressiveness.

This study shows nematodes transport bacteriophages in soil and compost through both cuticular attachment and ingestion, without requiring host bacteria.

The paper investigates how root-knot nematode density and cover crops affect the diversity and activity of nematode antagonists in agricultural soil.

The paper identifies susceptibility genes involved in trans-kingdom vitamin B synthesis between a plant-parasitic nematode and its host, revealing a horizontal gene transfer critical for parasitism.

The paper generates two new reference genomes for G. rostochiensis inbred lines and identifies effector family-specific diversification patterns that differ between pathotypes.

The paper investigates how the invasive plant giant goldenrod increases fungal biomass in soil and affects fungivorous nematode communities, finding a specific fungal community shift and nematode response.

The paper shows that conserved codon usage in highly expressed genes correlates with reduced mRNA secondary structure variability, enhancing translation efficiency and mRNA stability.
