Insights from draft genomes of Heterodera species isolated from field soil samples.

Background: The nematode phylum includes many species key to soil food webs with trophic behaviours extending from feeding on microbes to macrofauna and plant roots. Among these, the plant parasitic cyst nematodes retain their eggs in protective cysts prolonging their survival under harsh conditions. These nematodes, including those from the genus Heterodera, cause significant economic losses in agricultural systems.
