Oryza sativa BRASSINOSTEROID UPREGULATED1 LIKE1  ( OsBUL1 ) positively affects lamina inclination and grain size.  OsBUL1  knock-out ( osbul1 ) plants as well as transgenic rice with reduced level of  OsBUL1  expression produce erect leaves and small grains. Here, we identified a putative downstream gene of  OsBUL1, OsBUL1 DOWNSTREAM GENE1  ( OsBDG1 ) encoding a small protein with short leucine-rich-repeats by cDNA microarray analyses in the lamina joint and panicles of wild-type and  osbul1  plants. Transgenic rice plants with increased  OsBDG1  expression exhibit increased leaf angle and grain size, which is similar to an  OsBDG1  activation tagging line whereas double stranded RNA interference (dsRNAi) lines for  OsBDG1  knock-down generate erect leaves with smaller grains. Moreover, transgenic rice expressing  OsBDG1  under the control of  OsBUL1  promoter also shows enlarged leaf bending and grain size phenotypes. Two genes,  OsAP2  ( OsAPETALA2 ) and  OsWRKY24  were identified as being upregulated transcriptional activators in the lamina joint of p OsBUL1 : OsBDG1  plants and induced expression of the two genes driven by  OsBUL1  promoter caused increased lamina inclination and grain size in rice. Thus, our work demonstrates that a series of genes showing expression cascades are involved in the promotion of cell elongation in lamina joints and functionally cause increased lamina inclination.
