Do gibberellins inhibit flowering of transgenic pears with silenced TFL1-encoding genes?

A. Haberman, M.A. Flaishman, A. Samach
Recently we reported that high fruit load and flowering inhibition corresponds to transcript accumulation of MdTFL1-2, a postulated flowering inhibitor in apple (Malus domestica Borkh.). Our results also suggested that gibberellin (GA) inhibition of flowering in apple may be mediated through accumulation of MdTFL1-2. Here we asked if continuous flowering of transgenic pear (Pyrus communis L.) trees with silenced TFL1-encoding genes will be affected by exogenous GA treatment. The GA treatment reduced flower formation in the transgenic trees.
