The hop cyst nematode, , is the most common plant-parasitic nematode associated with hop worldwide. This study reports the draft genome of generated on the PacBio Sequel IIe System with the ultra-low DNA input HiFi sequencing method, and the corresponding genome annotation. This genome resource will help further studies on and other cyst nematodes.

The aim of this study was to determine whether both nematode species were similar in their ability to induce defense genes in roots of wheat genotype Scarlet, and whether a combination of both species induced a different pattern of gene induction than each species alone.

Plant-parasitic nematodes have been implicated in problems with the growth of plants in nurseries and are also of phytosanitary risk. A greenhouse experiment was conducted to evaluate the host status of four trees () and two shrubs , ) to , and .

- Plant-parasitic nematodes pose a significant threat to global crops, and the current move away from broad-spectrum nematicides limits farmers' control options.
- Researchers have discovered a new compound, Cyprocide, which selectively targets and kills various types of nematodes while sparing other organisms.
- Cyprocide is activated by specific nematode enzymes, highlighting its potential as a specialized solution to protect the food supply from nematode infestations.
Article Synopsis
- Plant-parasitic nematodes (PPN) are a less-known group of pathogens affecting cool-season grass seed crops in Oregon, and this survey identifies their presence in various grass species.
- The study sampled 37 fields during the 2022 and 2023 growing seasons, revealing significant differences in PPN community composition based on the type of grass host and the time of sampling.
- DNA sequencing techniques uncovered several nematode species, some of which are noted for the first time in association with these grasses, highlighting the need for more research on their impact on grass yield and health.
