Heterodera
Genus of roundworms From Wikipedia, the free encyclopedia
Remove ads
Heterodera is a genus of nematodes in the family Heteroderidae. Members of the genus are obligate parasites and different species attack different crops, often causing great economic damage. The genus is unique among nematode genera because of the ability of the female to transform into a tough, brown, cyst which protects the eggs which have been formed within her body.[1] The name heterodera "refers to the different 'skins' of female and cyst."[2]

Genetics
GenBank contains internal transcribed spacers sequences for the family, much of which is for this genus. Most of that has been generated by Sergei Subbotin and collaborators (Subbotin et al., 1999, Clapp et al., 2000, Subbotin et al., 2000, Zeng et al., 2000, Subbotin et al., 2001, Amiri & Subbotin 2002, Subbotin et al., 2003). Subbotin et al., 2003 suggests further analysis of this data will yield a large number of new Heterodera species.[4]
