Genetics Center (CGC): This
is the heart of all C. elegans research, located
in Saint-Louis, Missouri, U.S.A. and financed by the NIH.
The CGC collection contains thousands of frozen worm strains,
mostly C. elegans mutants generated by many labs,
but also a large number of wild isolates of C. elegans
as well as of other nematode species.
Systematics Resource Center: A database
maintained by David Fitch, New York University, with a repertoire
of wild nematode strains of several laboratories.
