Title: Genetic Analysis and Fine-Mapping of a Novel Dwarf Mutant in Rice
Abstract: Screening of dwarf mutants plays an important role in understanding of the molecular mechanism in rice plant architecture. We report here the identification and characterization of a novel rice dwarf mutant from tissue culture progeny of a Japonica variety Kitaake,dm. The mutant shows a pleiotropic phenotype,including dwarf,fragile stem,low fertility,and decreased 1000-grain weight. By using F2and its following segregated populations,we narrowe down dm gene into a 168 kb region on the long arm of chromosome 4. Our results indicate that DM represents a new locus responsible for rice plant architecture.
