  1. Lower case letters in the polyadenylation signal indicate differences from the canonical AAUAAA sequence. The position is the distance of the last base of the hexamer from the polyA start site, indicated as position 0. Tissue abbreviations: b: blood cells; cl: cleavage stage embryo; eg: egg; g: gonad; h: heart; tb: tailbud embryo. EST clones are detailed in Additional file 3.
