| Outline of Final Research Achievements |
A closed panicle is one of the key traits in the early stage of rice domestication. This trait is considered to lead significant reduction in seed shedding and outcrossing rate. Here, we first fine-mapped chromosomal regions responsible for the panicle shape, i.e., OsLG1 regulatory region and minor locus on chromosome 5. Seed awning and floral morphology are co-related to the seed shedding and pollination behavior, respectively. Genetic controls of these traits were also investigated. The above results confirmed that many loci of these traits were involved in rice domestication.
