A cDNA resource from the basal chordate <i>Ciona intestinalis</i>

Abstract

The genome of the basal choradate Ciona intestinalis contains a basic set of genes with less redundancy compared to the vertebrate genome. Extensive EST analyses, cDNA sequencing, and clustering yielded "Ciona intestinalis Gene Collection Release 1," which contains cDNA clones for 13,464 genes, covering nearly 85% of the Ciona mRNA species. This release is ready for use in cDNA cloning, micro/macroarray analysis, and other comprehensive genome-wide analyses for further molecular studies of basal chordates.
