This document provides a taxonomy of major bacterial and eukaryotic groups, listing their phylogenetic classification and some representative genera in each group. It covers bacteria in the domains of Archaea and Bacteria. For eukaryotes, it discusses the kingdoms of Protista, Plantae, Fungi and Animalia.
