• Key message
  • Here, we show that mutation of the rice (Oryza sativa) gene TONGARI-BOUSHI1 (TOB1) results in pleiotropic phenotypes in spikelets, such as the formation of a cone-shaped organ instead of the lemma or palea, the development of two florets in a spikelet, or premature termination of the floret meristem, in addition to reduced growth of the lemma or palea and elongation of the awn
  • No TOB1 expression is detected in the meristem, so TOB1 may act non-cell autonomously to maintain proper meristem organization and is therefore likely to play an important role in rice spikelet development
  • TOB1 encodes a YABBY protein, which is closely related to FILAMENTOUS FLOWER in Arabidopsis thaliana, and is expressed in the lateral organ primordia without any patterns of polarization
• Connection
  • NAL2~OsWOX3A~WOX3, OsYABBY5~OsYAB3~TOB1, A WUSCHEL-LIKE HOMEOBOX gene represses a YABBY gene expression required for rice leaf development, Here, we report the characterization of functional relationship between rice (Oryza sativa) YAB3 and WOX3 in rice leaf development
  • NAL2~OsWOX3A~WOX3, OsYABBY5~OsYAB3~TOB1, A WUSCHEL-LIKE HOMEOBOX gene represses a YABBY gene expression required for rice leaf development, Rice YAB3 is closely related to maize (Zea mays) ZmYAB14 and Arabidopsis (Arabidopsis thaliana) FILAMENTOUS FLOWER (FIL), whereas rice WOX3 is highly conserved with maize narrow sheath1 (NS1) and NS2 and Arabidopsis PRESSED FLOWER (PRS)
  • NAL2~OsWOX3A~WOX3, OsYABBY5~OsYAB3~TOB1, A WUSCHEL-LIKE HOMEOBOX gene represses a YABBY gene expression required for rice leaf development, Overexpression of WOX3 repressed YAB3 and showed a YAB3 RNAi phenotype
  • NAL2~OsWOX3A~WOX3, OsYABBY5~OsYAB3~TOB1, A WUSCHEL-LIKE HOMEOBOX gene represses a YABBY gene expression required for rice leaf development, The expression of class I KNOTTED-LIKE HOMEOBOX (KNOX) genes was ectopically induced in leaves of YAB3 RNAi or WOX3 overexpression plants
  • NAL2~OsWOX3A~WOX3, OsYABBY5~OsYAB3~TOB1, A WUSCHEL-LIKE HOMEOBOX gene represses a YABBY gene expression required for rice leaf development, Data from inducible WOX3 expression and DNA-protein interaction assays suggested that WOX3 acted as a transcriptional repressor of YAB3
  • NAL2~OsWOX3A~WOX3, OsYABBY5~OsYAB3~TOB1, A WUSCHEL-LIKE HOMEOBOX gene represses a YABBY gene expression required for rice leaf development, These data reveal a regulatory network involving YAB3, WOX3, and KNOX genes required for rice leaf development
  • OsMADS1~LHS1~AFO, OsYABBY5~OsYAB3~TOB1, Genome-wide targets regulated by the OsMADS1 transcription factor reveals its DNA recognition properties., We show that the expression status of these nodal factors can be altered by inducing the OsMADS1-GR fusion protein and present a model for a regulatory cascade where the direct targets of OsMADS1, OsbHLH108/SPT, OsERF034 and OsHSF24, in turn control genes such as OsMADS32 and OsYABBY5
