Abstract
In previous research, we found that one possible mechanism to be variegated flower color phenotypes is caused by transposition of transposable element dTdic1 in Dianthus caryphyllus. dTdic1 was an Ac/Ds-like transposable element, and more than 20 copies of dTdic1 family were found in the carnation genome. The cyanic color of most flowers comes from anthocyanins, while betacyanins produce the color in flowers of Centrosparmae excluding Dianthus. Mirabilis nyctaginaceae is one of flower, which produces betacyanins, and it has many flowers mutable with variegated flower color phenotypes, which might be caused by transposable element. It is thought that transposable elements play a very important role in altering the genome during evolution, but it is unknown in how it has spread. We identified a transposable element, Tnm1, which belongs to an Ac/Ds superfamily, but it was different from dTdic1 structurally. We report about a relation between the insertions of Tnm1and flower color.
