| Outline of Final Research Achievements |
We made attempts to isolate new inflorescence branching pattern mutants for isolation of new key genes controlling panicle architecture. Several mutants were selected for the new traits that have not been reported, which would illuminate mechanisms underlying pattern formation of rice panicle morphology. In the efforts to elucidate the mechanisms connecting between genes controlling panicle branching pattern and meristem organization, we constructed double mutants between lonely guy(log) and panicle patterning mutants. So far we have identified a population segregating both log and moc1 mutants, indicating analysis of mutants in the population lead to identification of log moc1, may elucidate the role of cytokinin in the moc1 controlling branching pathway. We also introduced DR5 driven DSRED gene into aberrant panicle organization2 (apo2) mutant to investigate the auxin accumulation pattern under apo2 background.
