To better understand the evolution and functions of these enigmatic RNAs  we used chromatin marks  polyA site mapping and RNA Seq data  to identify more than 550 distinct lincRNAs in zebrafish. Although these shared many characteristics with mammalian lincRNAs  only 29 had detectable sequence similarity with putative mammalian orthologs  typically restricted to a single short region of high conservation. Other lincRNAs had conserved genomic locations without xxx sequence conservation. Antisense reagents targeting conserved regions of two zebrafish lincRNAs caused developmental defects. Reagents targeting splice sites caused the same defects and were rescued by adding either the mature lincRNA or its human or mouse ortholog. Our study provides a roadmap for identification and analysis of lincRNAs in model organisms and shows that lincRNAs play crucial biological roles during embryonic development with functionality conserved despite limited sequence conservation.
