Annotated Information

Function

DWARF TILLER1 (DWT1) controls the developmental uniformity of the main shoot and tillers in rice (Oryza sativa). DWT1 mutant has no obvious morphological difference with wild-type plant at the initial vegetative stage. However, DWT1 developes dwarfed tillers with the main shoot having nearly normal height during the reproductive stage. DWT1 tillers have shorter internodes with fewer and un-elongated cells, indicating that DWT1 affects cell division and cell elongation. DWT1 encodes a WUSCHEL-related homeobox (WOX) transcription factor homologous to the Arabidopsis WOX8 and WOX9.

Expression

The DWT1 gene is highly expressed in young panicles, but undetectable in the internodes, suggesting that DWT1 expression is spatially or temporally separated from its effect on the internode growth. Altered expression of genes involved in cell division and cell elongation, cytokinin/gibberellin homeostasis and signaling have been revealed in DWT1 shorter internodes. Previous reports indicated no effect of these hormonal pathways on the coordination between the tiller and the main shoot growth, but latest resoults reveals that the DWT1 activity is directly or indirectly associated with GA signaling in the internode elongation.
