| Research Abstract |
The transcription factor RIN, which regulates tomato fruit ripening, was examined for its molecular properties and for the effect of the rin mutation. The results revealed that RIN is a nuclear localized protein that has a ability to bind specific DNA motif and a transcription-activating function. By the rin mutation, the encoding protein lost its transcription-activating function but kept the DNA binding ability. These results suggest that the functional defect of the mutant protein cause the inhibition of the fruit ripening in the mutant and the partial inhibition in the RIN/rin hetero plant.
