Knockdown of RBP-L confers several growth defects in rbpl line in comparison to wild type. A, Seed morphology of wild-type and rbpl line. Scale bar = 1 cm. B, Germinated wild-type and rbpl seeds after 6 d of imbibition. Scale bar = 1 cm. C, Germination rate of wild-type and rbpl seeds. Seeds were considered germinated when the radicle was extended >1 cm or more. D, The rbpl line showed late flowering and dwarfism. When rbpl line plants were blooming, the grains from wild-type plants were approaching maturity. E, The rbpl lines showed lower spikelet fertility than wild type. Some empty glumes on the rbpl tassel are indicated by arrows. WT, wild type.
