  1. SAGE libraries were prepared from total RNA of dorsal and ventral explants of X. tropicalis gastrula. Concatemer sequences were processed for tag extraction and comparison between libraries. *Repeated ditags were considered only once. Tags including 'N' in the sequence were not considered (eight tags in the dorsal library and ten tags in the ventral library).
