摘要：

To create an ornamental plant that repels pests, transgenic torenia (Torenia fournieri Lind.) plants were generated expressing the 1,8-cineole synthase (CINS) from lavandin (Lavandula × intermedia Emeric ex Loisel.) under the control of the petal-specific MYB1 promoter of morning glory (Ipomoea nil L.). All the regenerated transgenic plants showed CINS expression in petals but did not show morphological differences compared with non-transgenic plants. In regenerated transgenic CINS6 and CINS8 plants, which exhibited higher expression of CINS than the other transgenic plants, 1,8-cineole was detected in the head space above whole plants. Furthermore, in a two-choice assay using florets, CINS6 petals demonstrated significant repellent effects against western flower thrips (Frankliniella occidentalis (Pergrande)) compared with the non-transgenic control petals. These results suggest another way to prevent pest damage by herbivores in ornamental plants by releasing transgenic volatile compounds from florets.
