Investigation of the Transcriptome of Prairie Cord Grass, a New Cellulosic Biomass Crop
MetadataShow full item record
AbstractPrairie cordgrass (Spartina pectinata Bosc ex Link) is being developed as a cellulosic biomass crop. Development of this species will require numerous steps, including breeding, agronomy, and characterization of the species genome. The research in this paper describes the first investigation of the transcriptome of prairie cordgrass via Next Generation Sequencing Technology, 454 GS FLX. A total of 556,198 expressed sequence tags (ESTs) were produced from four prairie cordgrass tissues: roots, rhizomes, immature inflorescence, and hooks. These ESTs were assembled into 26,302 contigs and 71,103 singletons. From these data were identified, EST-SSR (simple sequence repeat) regions and cell wall biosynthetic pathway genes suitable for the development of molecular markers which can aid the breeding process of prairie cordgrass by means of marker assisted selection.
