Sylvain Lapan and Peter Reddienat at the Whitehead Institute for Biomedical Research in Cambridge, Mass., this week report on the complete transcriptome of the eye of the planarian Schmidtea mediterranea. Writing in Cell Reports, Lapan and Reddienat show that transcription factor Ovo is required for eye formation in S. mediterranea and add that the "planarian eye expresses orthologs of eye disease genes."
