Outline of Final Research Achievements

To understand regulatory mechanisms of RNA silencing and gene expression in plants, we characterized the pigmentation patterns that are regulated by small RNA in flowers of the Japanese morning glory. The results of small RNA and mRNA sequence analysis suggested that a specific RNA silencing pathway is activated in a particular pigmentation pattern. In addition, we sequenced whole genome of the Japanese morning glory. By the analyses using the whole genome sequence, several candidate genes controlling pigmentation patterns were identified.
