It was found that there were 36 distinct differences in 184 protein spots. In-gel digestion and liquid chromatography mass spectrometry C LC-MS were made to analyze the protein SSP2801, and Mascot software was applied to identify the protein. The results showed the protein was large subunit of Rubisco, and its content in yellow mutant decreased distinctly, only about 26% of the comparison. Maybe it has relation to etiolation.
