Coomassie Brilliant Blue (CBB)-stained two-dimensional electrophoresis gels of proteins in mitochondria of mesophyll cells of diploid (2×) R. pseudoacacia under 0, 250 mM and 500 mM NaCl treatment. Poteins were separated on 13 cm IPG strip (pH 4–7 linear gradient) usig isoelectric focusing, followed by sodium dodecyl sulfate polyacrylamide gel electrophoresis on a 12.5% gel. a 0 mM NaCl; b 250 mM NaCl; c 500 mM NaCl. The proteins information are listed in Table 2 and Additional file 1: Table S1
