Outline of Final Research Achievements

In the time and organ specific anthocyanin biosynthesis in the petals of Eustoma, it is suggested that signal molecule mediating. In this study, endogenous jasmonic acid and methyl jasmonate were estimated as the signal molecules. To increase the reliability of the results, further experiments, such as gene expression, are under continuing investigation.
