TIGR gene indices

The Institute For Genomic Research has great resources for studying ESTs and genomic DNA from a variety of organisms; here are links to a few of them.

TIGR BLAST: Sequence searches of dozens of organisms.
Eukaryotic Gene Orthologs: Searchable database of orthologous genes.
Unfinished Genomes Search: BLAST searches of sequencing projects currently underway at TIGR.
TIGR Genome Projects: Self-explanatory; pretty cool.
