Gravity exerts a profound influence on plant growth. Proteomics may be the most promising technique to identify the proteins that are induced, repressed, or post-transcriptionally modified during gravity response in plants. In this research, the proteins controlled by gravity condition were identified. First, total protein extracted from Arabidopsis seedlings grown in 1 G-stationary and clino-rotated condition for seven days was used. Then, gravity-regulated proteins expression was analyzed by two-dimensional gel electrophoresis (2-DE). Several proteins which appeared different expressions between stationary and clino-rotated conditions were identified by Matrix Assisted Laser Desorption Ionization - Time Of Flight Mass Spectrometry (MALDI-TOFMS) analysis and Peptide Mass Fingerprinting (PMF).
