Rice Bioresource Topics: Genetic Resources Indispensable for Studies of Evolution, Diversity and Functional Genomics in Rice.

Abstract

The rice genetic resource project progressed in the National Bioresource Project (NBRP) deals with three major resources. One is wild rice of more than 3000 accessions those covers 9 genomes and 23 species. The second is series of chromosome substitution lines of cultivars with fragments of wild or different ecotype strains. The last one is MNU-induced mutant lines of japonica rice highly concentrated with mutations. The wild rice would be more important for evolutional and diversity studies following full genome comparative studies being carried out in US. The MNU-induced mutant populations have revealed to contain highly concentrated mutations by surveying TILLING system. This could be very powerful resource for identifying mutant alleles of any target genes in rice. In my talk, these recent topics about rice bioresources will be presented.
