This spot was identified in the leaves of clone 14 of C. canephora under the WS condition. Six peptides from MALDI-TOF/TOF tryptic mass spectra (Figure 7) were sequenced by MS/MS ion search and de novo sequencing. They are also reported in Figure 3. The peptides position refers to the full-length RBCS1 protein. Peptide masses are shown as the monoisotopic mass (M+H).
