- 42. The pyrimidine-chemical properties to delete marginal picotee pattern in Petunia petals
抄録
Beautiful coloration patterns in corollas are a commercially important factor and found in various floricultural plants. These patterns are formed due to uneven distribution of pigments caused by the site-specific regulation of pigment biosynthesis. We have found a pyrimidine-chemical to change flower patterns of Petunia. The chemical changed white marginal picotee patterns of such cultivars, resulting in blooming pattern-less flower from 15 to 20 days after treatment. The chemical was also effective to white vein sectoral cultivars but gave no visual change to a white central picotee cultivar and a whole colored cultivar. The white marginal picotee pattern is generated by marginal site-specific repression of chalcone synthase (CHS) expression. By the chemical treatment, the site-specific difference of CHS expression disappeared, and moreover, the expression of CHS was drastically increased in the whole petal tissues. The chemical has an activity to release the repression of CHS expression in the marginal tissue, resulting in uniform pigmentation of the whole petal.
