Identification of proteins in gel bands according to band number and sample type: 8-week-old cotyledonary somatic embryo (SE), zygotic embryo (ZE) and megagametophyte (Mega) in the hybrid larch (Larix × eurolepis). The excised band number refers to the spot label in Fig. 4. The assignments were found via the MASCOT software package (, from the UniProt database ( by the PEAKS identification engine. #pep.: number of matching peptides; % cov.: coverage percentage; ano storage protein found.
ppl12081-sup-0002-AppendixS2.docWord document110KAppendix S2. Spots containing more than one putatively identified protein, presented according to hybrid larch (Larix × eurolepis) somatic embryo stage: 1 week (immature SE) or 8 weeks (cotyledonary SE). The excised spot number; refers to the spot number in Fig. 5. The assignments and accession numbers were found in the DFCI database ( by the PEAKS identification engine. The most homologous protein in the UniProt database ( and its species affiliation are given. Theoretical molecular mass (Mr) and isoelectric point (pI) were computed at the ExPASy website ( whereas the experimental Mr and pI were determined according to spot position on the 2D gel. # pep.: number of matching peptides; % cov.: coverage percentage.
