Dormancy and hatching of nematode eggs.
The sequence of events during the hatching process of some parasitic nematodes has been the subject of recent detailed study. Certain factors, such as the trehalose content of the perivitelline fluid and the permeability characteristics of the eggshell, are influential in hatching and are also important for the survival of dormant, unhatched juveniles. In this review, Roland Perry examines some attributes of the egg that are involved in dormancy and survival of nematodes and details the changes that occur during the hatching process.
