      synthesis in dahlia (Dahlia variabilis).

AB  - Dahlias (Dahlia variabilis) exhibit a wide range of flower colours because of 
      accumulation of anthocyanin and other flavonoids in their ray florets. Two 
      lateral mutants were used that spontaneously occurred in 'Michael J' (MJW) which 
      has yellow ray florets with orange variegation. MJOr, a bud mutant producing 
      completely orange ray florets, accumulates anthocyanins, flavones, and butein, 
      and MJY, another mutant producing completely yellow ray florets, accumulates 
      flavones and butein. Reverse transcription-PCR analysis showed that expression of 
      chalcone synthase 1 (DvCHS1), flavanone 3-hydroxylase (DvF3H), dihydroflavonol 
      4-reductase (DvDFR), anthocyanidin synthase (DvANS), and DvIVS encoding a basic 
      helix-loop-helix transcription factor were suppressed, whereas that of chalcone 
      isomerase (DvCHI) and DvCHS2, another CHS with 69% nucleotide identity with 
      DvCHS1, was not suppressed in the yellow ray florets of MJY. A 5.4 kb CACTA 
      superfamily transposable element, transposable element of Dahlia variabilis 1 
      (Tdv1), was found in the fourth intron of the DvIVS gene of MJW and MJY, and 
      footprints of Tdv1 were detected in the variegated flowers of MJW. It is shown 
      that only one type of DvIVS gene was expressed in MJOr, whereas these plants are 
      likely to have three types of the DvIVS gene. On the basis of these results, the 
      mechanism regulating the formation of orange and yellow ray florets in dahlia is 
      discussed.
