| Outline of Final Research Achievements |
In order to elucidate the molecular mechanism underlying the regulation of floral organ (FO) size in rice, we analyzed two mutants; 1) miniature floral organs (mif) in which the NUMBER of FOs are not altered, but the SIZE of FOs are reduced to less than half of wild type, 2) short anther (san) in which the stamens (especially the anthers) are specifically shortened. Double mutants between mif and fon1 in which the floral meristem (FM) are enlarged showed small FOs, indicating regulatory mechanisms between FM size and FO size are independent. We also identified that the MIF gene encodes a member of chromatin remodeler-like proteins, and SAN encodes an adapter-like protein.
