Nematodes play a crucial role in soil ecosystems by breaking down organic matter and regulating microbial populations.

In the agricultural study, scientists found a nematode that was reducing crop yields by damaging the roots.

The nematodal infection devastated the root system of the tomato plants.

Steiner's spiral nematode infested the soybean roots, reducing yields across several fields.

Under the electron microscope, the nematodesmata were clearly visible supporting the oral cilia as the protozoan fed.
