Abstract excerpt

The organ size of flowering plants is determined by two post-embryonic developmental events: cell proliferation and cell expansion. In this study, we identified a new rice loss-of-function mutant, small organ size1 (smos1), that decreases the final size of various organs due to decreased cell size and abnormal microtubule orientation. SMOS1 encodes an unusual APETALA2 (AP2)-type transcription factor with an...
