Floral organ development is fundamentally important to plant reproduction andseed quality,yet its underlying regulatory mechanisms are still largely unknown,especially incrop plants.In this study,we characterized rice null mutant osarf19,which was isolated froma T-DNA insertion pool.The mutant displayed three types of abnormal florets:an enlargedand degenerated palea,and an additional lemma.It also showed enlarged plant architecture,including elongated basal internodes and leaves.Cellular morphology and quantitativereal-time PCR(qRT-PCR)analyses showed that cell elongation caused the enlarged organs.
