Magnification of the tryptic mass spectra of the ions M+H 1472.9 and M+H 1489.9. The spot numbers correspond to RBCS1 isoforms identified by 2-DE gel electrophoresis in the leaves of clone 14 of C. canephora under NI conditions. The x-axis represents the mass-to-charge (m/z) ratio and the y-axis represents the intensity of peaks expressed in arbitrary units (a.u.). The mass difference between ions of 17 Da corresponds to the loss of ammonia.
