Trophosome and plume sequences from Ridgeia piscesae.

*Genes previously reported as being expressed in the trophosome [40].ESTs contigs and 454 isotigs were identified using the BLAST-based analysis program BLASTX (National Center for Bioinformatics Information; NCBI; [85], which compared our sequence to six non-redundant peptide sequence databases (GenBank CDS translations, RefSeq Proteins, PDB, SwissProt, PIR, and PRF). Sequences with E values of –6 were categorized and quantified according to the functional category of the homologous gene. Source sequence tissue databases are: T, Trophosome; P, Plume; B, Both.
