In order to assess the effect of gravity on life cycle in the Arabidopsis plant, we have organized a working group, consisting of 29 members from different research fields of plant science. The goal of our working group is to clarify whether or not the seed to seed life cycle of a higher plant, Arabidopsis thaliana L., is normally completed under microgravity condition in the International Space Station, using plant experiment units embarked in JAXA's cell biology experiment facility with a centrifuge to produce 1 g condition. In this year, we examine the effect of hypergravity (300 x g) on proteome in floral buds. Proteins were extracted from floral buds excised from plants grown at 300 x g or 1 x g for 24 hr, and then subjected to two dimensional electrophoresis. It was turned out that hypergravity increased the expression of 9 protein spots, and decreased that of 5 spots. These protein spots were analyzed by matrix-assisted laser desorption ionization time flight mass spectrometry. Proteomics results were compared with our previous transcriptome data.
