Outline of Final Research Achievements

Sensing of gravity in plants is composed of amyloplast sedimentation (PGM pathway) and ARG1 pathway. However, a gravity-sensing molecule that converts gravistimulation into intracellular signals has not been identified. In this study, we found that gravity-responses in arg1 pgm double mutants could be detected under the hypergravity condition that was created by a low-speed centrifuge. Therefore, we screened M2 seedlings of arg1 pgm double mutants that were mutagenized with EMS, and isolated 4 lines of enhancer of arg1 pgm mutants that exhibited less gravity-responses than arg1 pgm mutants did. Hereafter, we expect that analysis of these mutants will allow us to obtain a new insight of how plants sense gravity.
