Abstract

There are many kinds of horticultural flowers showing various coloration patterns. These patterns are reflected by operation of sitespecific regulation of pigments biosynthesis. We are studying generation mechanism of marginal picotee pattern in petunia petal, where anthocyanins are major pigments. We found that treatment of some pesticides changed the pattern in a marginal picotee cultivar with white margin and colored center, resulting in blooming pattern-less colored flowers. The pattern-less flowers bloomed from the second to the third week after treatment, suggesting that these pesticides act in buds at the early growth stage. We have indicated that marginal site-specific repression of mRNA of chalcone synthase is involved in the formation of white marginal tissue and the repression probably operates at post-transcriptional steps. These pesticides seem to have activities to release the repression.
