| Research Abstract |
In this study, TfMYBML1, TfMYBML2, and TfMYBML3 isolated from Torenia fournieri were found to inhibit the expression patterns of different genes according to petal development of torenia. Analysis of TfMYBML1-, TfMYBML2-, and TfMYBML3-suppressed transgenic torenia plants suggested that TfMYBML3 is closely related to the epidermal cell differentiation of a yellow blotch on the lower petal. However, each transgenic torenia plant constitutively overexpressing TfMYBML1, TfMYBML2, and TfMYBML3 showed the same phenotype as the wild-type plant. These results suggest that TfMYBML1, TfMYBML2, and TfMYBML3 are not the main factors responsible for controlling epidermal cell shape in the petals of T. fournieri
