ZAP, lambda ZAP II (pBluescript) phage vector; pGEM, pGEM-t plasmid vector; %"N", percentage of ambiguous nucleotides. Ovary and testis includes the accessory glands of the reproductive organs. Clustering was performed using CLOBB [25]. ESTs are deposited in the DNA databases under accession numbers DB20956–DB858077 (37,122 entries).
