HaloWeb: The Haloarchaeal Genomes Database

This is the home page for genome projects aimed at haloarchaeal microorganisms located at the University of Maryland. The organisms listed here can grow in salinity greater than that of sea water and are members of the archaeal branch of life. For an overview on archaea, see the Desk Encyclopedia of Microbiology. For a discussion of nomenclature and taxonomy of haloarchaea, read the Commentary in Saline Systems. For a site on the use of haloarchaea for education, see HaloEd. For gene naming conventions and conversions, click here. For login privileges, please contact Prof. S. DasSarma. This website is supported by a grant to SSLEEC. Publications referencing HaloWeb should cite: Saline Systems 6, 12 (2011).
