AB  - Carpel suppression is a trigger for sexual dimorphism in the dioecious plant 
      Silene latifolia. To clarify what kind of genes are involved in carpel 
      suppression in this species, we generated a bisexual mutant, R025, by C-ion beam 
      irradiation. R025 produces bisexual flowers with a mature gynoecium and mature 
      stamens. Genetic analysis of R025 attributed the bisexual trait to mutations on 
      the Y chromosome. Scanning electron microscopy (SEM) analysis of early floral 
      development revealed that the carpel size of R025 was different from that of 
      wild-type males in spite of the male background in R025. We also identified an S. 
      latifolia CLAVATA1-like gene (SlCLV1) as a candidate of the CLAVATA-WUSCHEL 
      (CLV-WUS) pathway. Two separate pathways, the CLV-WUS pathway and the CUP-SHAPED 
      COTYLEDON (CUC)-SHOOT MERISTEMLESS (STM) pathway, contribute to carpel 
      development in the Arabidopsis floral meristem. SlSTM1 and SlSTM2 (orthologs of 
      STM) and SlCUC (an ortholog of CUC1 and CUC2) have already been identified in S. 
      latifolia. We therefore examined the expression patterns of SlCLV1, SlSTM (SlSTM1 
      and SlSTM2) and SlCUC in young flowers of R025 and wild-type males and females. 
      The expression patterns of the three genes in the two pathways differ between the 
      wild-type male and the bisexual mutant, and the differences in expression 
      patterns of the three genes occur at the same stage. These results suggest that 
      in addition to SlSTM1, SlSTM2 and SlCUC, SlCLV1 is also involved in carpel 
      suppression in S. latifolia. They also suggest that a gynoecium-suppressing 
      factor (GSF), which is lost in the R025 Y chromosome, acts on an upstream gene 
      that is common to the two pathways, triggering sexual dimorphism in S. latifolia.
