The first of its kind, this laboratory handbook emphasizes diverse methods and technologies needed to investigate C. elegans , both as an integrated organism and as a model system for research inquiries in cell,developmental, and molecular biology, as well as in genetics and pharmacology. Four primary sections--Genetic and Culture Methods, Neurobiology, Cell and Molecular Biology, and Genomics and Informatics--reflect the cross-disciplinary nature of C. elegans research. Because C. elegans is a simple and malleable organism with a small genome and few cell types, it provides an elegant demonstration of functions fundamental to multicellular organisms. The discipline has greatly expanded as researchers continue to find this small soil nematode to be the model of choice for studying specific pathways, stages of development, and cell types. By directing its audience not just to tried-and-true recipes for research, but also to databases and other innovative sources of information, this comprehensive collection is intended to guide investigators of C. elegans for years to come.
