| Research Abstract |
We analyzed floral anthocyanin synthesis genes to determine the causal factor of white and yellow flowers and differences between red and salmon in commercial petunia cultivars. We intended to decipher breeding history of cultivars by comparing the causal genes with those of wild species. We found the first evidence of involvement of P. inflata in causal gene of white flower. The cause of the vein pattern derived from P. axillaris. For the yellow and the deciding factor between red and salmon, we found the gene that was down regulated, but did not find the cause for that.
