Plant-parasitic nematodes spend much of their lives inside or in contact with host tissue and molecular interactions constantly occur and shape the outcome of parasitism. Eggs of these parasites generally hatch in the soil, and the juveniles must locate and infect an appropriate host before their stored energy is exhausted. Components of host exuda...
