Plant life cycle consists of successive phases of vegetative and reproductive growth. The effects of altered gravity conditions on reproductive growth are not understood well compared to vegetative growth. We have performed proteome analysis to examine the effect of hypergravity on reproductive growth of Arabidopsis (Arabidopsis thaliana (L.) Heynh. ecotype Columbia-0). Plants grown for 20-26 days under were exposed to hypergravity at 300 x g or placed at 1 x g for 24 h in the dark. Proteins extracted from the flower buds with a buffer containing Triton X-100 were subjected to two-dimensional electrophoresis. The polypeptides, that were up-regulated or down-regulated by hypergravity, were analyzed by matrix-assisted laser desorption ionization time of flight (MALDI-TOF) mass spectrometry, to compare the present proteome results with our previous transcriptome results. Proteome analysis showed that hypergravity changed the expression of proteins involved in protein folding and translocation, ethylene synthesis and stress response.
