Protist Sequence Space: What’s Out There?

In the following Table, Eukaryote taxa are listed with emphasis on protists. The numbers in parentheses after the Genbank taxa are the number of entries in Genbank. The PR-#s refer to the phyla of the Protoctista according to Margulis and Schwartz. (Margulis, L. and Schwartz, K.V. Five Kingdoms an illustrated guide to the phyla of life on earth. Freeman, New York 1998) Baldauf and Doolittle refers to their recent paper on phylogeny of eukaryotes (Baldauf SL, Roger AJ, Wenk-Siefert I, Doolittle WF. A kingdom-level phylogeny of eukaryotes based on combined protein data. Science. 2000 Nov 3;290(5493):972-7.) Note that some lower eukaryote taxa have significant sequence sampling.
