[CPGN] The database contains approved genefamily names and synonyms for all photosynthetic organisms, plant viruses, and the mitochondrial genes of many organisms.
Ribosomal Database Project II
[Center for Microbial Ecology] The Ribosomal Database Project (RDP) compiles ribosomal sequences and related data and redistributes them in aligned and phylogenetically ordered form. These sequences are drawn from various rRNA collections such as GenBank and from individual laboratories around the world. The database contains over 3000 aligned small subunit (SSU) and large subunit (LSU) ribosomal RNA sequences. Prokaryotic sequences predominate.
SRPDB: Signal Recognition Particle Database
[Univ of Texas Health Center] Provides annotated SRP RNA sequences from eukaryotes and archaea, phylogenetically ordered and aligned with their bacterial equivalents. We also make available representative RNA secondary structure diagrams where each base pair is proven by comparative sequence analysis.
The Tree of Life
[U. of Arizona] The Tree of Life is a project designed to contain information about the phylogenetic relationships and characteristics of organisms, to illustrate the diversity and unity of living organisms, and to link biological information available on the Internet in the form of a phylogenetic navigator.
[Harvard University] A relational database of phylogenetic trees and the data matrices used to generate them.
[University of Texas Health Center at Tyler] A tool in the study of the structures and functions of various uRNA's that provides aligned, annotated, and phylogenetically ordered sequences.
