PacBio’s new Iso-Seq technology allows for rapid generation of full-length cDNA sequences without the need for assembly steps. The technology was tested on leaf mRNA from two model O. sativa ssp. indica cultivars – Minghui 63 and Zhenshan 97. Even though each transcriptome was not exhaustively sequenced, several thousand isoforms described genes over a wide size range, most of which are not present in any currently available FL cDNA collection. In addition, the lack of an assembly requirement provides direct and immediate access to complete mRNA sequences and rapid unraveling of biological novelties.
