The class assignment presented in alphabetical order is based on the description of the best match from BLASTX similarity searches to the non-redundant GenBank protein databases. The number of EST clones and the percentage of the total from each category in the seed EST database are listed. (Note: cDNAs that were sequenced from both 5′ and 3′ ends were counted only once. Forty-one clones were not counted, which repeatedly returned incomplete BLAST results.
