In these proceedings of the Fourth International Rice Genetics Symposium held in October 2000 at the International Rice Research Institute, renowned geneticists have contributed to a wide range of topics - from the most advanced research on sequencing of the rice genome to functional genomics. This volume reviews the latest advances in rice research and provides in-depth discussion and exchange of information on classical genetics, biosystematics and evolution, molecular markers, transformation, genome organization, gene isolation, regulation of gene expression, sequencing of the rice genome, and bioinformatics.
