| Outline of Final Research Achievements |
Lilies (Lilium spp.) are one of the most important floricultural crops worldwide. The lack of reverse genetics tools and gene-sequence information has made it challenging to evaluate the genetic backgrounds of useful traits such as flower colours. In this study, virus-induced gene silencing technique was established using Cucumber mosaic virus as a viral vector, and the sequences expressed in flower tepals were categorized using an RNA-seq technique. In addition, useful genes that determined flower colours in lilies were clarified: LhMYB12-Lat determined splatter-type flower spots in Asiatic hybrid lilies, LhMYB15 was responsible for the light-responsive bud-blush phenotype in Lilium regale, and two independent genes respectively generated white flowers in Lilium speciosum.
