Root gall nematode

Root-gall nematodes are plant-parasitic nematodes from the genus Subanguina that affect grasses, including cereals, and some other plants, such as mugwort. They are distinct from the Root-knot nematodes which are from the genus Meloidogyne. So far around twenty-five separate species of Subanguina have been identified, although the most well-known and type species is Subanguina radicicola.
