| Research Abstract |
We analyzed flower color and floral anthocyanin of the cultivars of Phlox drummondii and P. subulata, and found that P. drummondii showed wider variety of colors than P. subulata, and the cause was that P. drummondii produced six anthocyanidins while P. subulata did only two. The factor that differentiates cyanidin and malvidin derivatives in P. drummondii cultivars was the expression level of F3'5'H gene, and the cis-elements differed among three alleles. Phylogenetic analysis of chloroplast DNA of P. subulata cultivars revealed the involvement of other species than P. subulata.
