Figure 2.

The structure of CMADS1, 2, 3, 4, and 6 cDNAs. The symbols ○, □, and § indicate the positions of the translation initiation and termination codons and poly(A)⁺ tails, respectively. Plain boxes indicate the MADS box, and the hatched boxes indicate the K box. The position of the initiation codon of CMADS6 is based on the CRM3 gene (11), which has the same amino acid sequences as the CMADS6. The dotted line of the CMADS6 represents unknown upstream sequences. The probes used for RNA expression analyses are indicated.
