Outline of Final Research Achievements

Cell-cell communication via plasmodesmata is important to control growth and environmental response in plants. However, the molecular mechanism is largely unknown.
We developed a quantitative method to analyze cell-cell communication by using a photoconvertible fluorescence protein, Dendra2 in protonemata of the moss, Physcomitrella patens, and studied a regulation of Dendra2 movement. We found two factors that are involved in abscisic acid signaling play a key role to control abscisic acid-dependent suppression of Dendra2 movement.
