Engineering Variegated Floral Patterns in Tobacco Plants Using the Arabidopsis Transposable Element Tag1

Dong Liu1, Mary Galli and Nigel M. Crawford2

Division of Biology, University of California at San Diego, La Jolla, CA 92093–0116, U.S.A.

Variegated flower phenotypes were generated using the Arabidopsis transposon Tag1 and the maize R regulatory gene. Tag1 was inserted between the CaMV 35S promoter and the maize R gene and transformed into tobacco plants. In half of the transgenic plants, variegated flower patterns were observed. Each line had a different pattern, with varying intensities with three lines showing only tiny sectors indicative of late excision and one showing large sectors indicative of earlier excision.
