Satellite Symposium 5: Molecular Breeding
Description
Comparative mapping studies in the family Poaceae, which includes rice (a model species for this family) and perennial ryegrass (PRG) have indicated macro-colinearity of genes is generally conserved across different genomes. Genome mapping of simple sequence repeat markers derived from expressed sequence tags (EST-SSRs) for PRG (Faville et al., 2004) provides a vehicle for DNA sequence-based matching of mapped PRG genes to orthologous positions in the rice genome, which can be used to establish comparative relationships between these species’ genomes. We have initiated such an analysis using an EST-SSR-based PRG genome map. Our objective was to assess this in silico approach as a tool for candidate gene identification from rice, and for targeting markers to specified PRG genome map regions based on rice genome position.
