Figure 6.

Visualization of putative interactions and processes mediated by the identified differentially abundant proteins. The network was constructed by String 11.0 [15], which employed an orthologous analysis of Solanum tuberosum proteins. Highlighted clusters revealed functional enrichments in the network based on biological process (gene ontology, GO) and metabolomic pathways (KEGG: Kyoto Encyclopedia of Genes and Genomes). In total, five distinct clusters are visible, including protein biosynthesis processes (ribosome and protein processing), glutathione metabolism, purine metabolism, and overlapping processes in primary and energetic metabolism (amino acid biosynthesis, TCA, and glyoxylate metabolism). Blue, red and purple arrows indicate observed changes in protein abundances for seeds incubated with hydrogen peroxide at 25 °C, seeds incubated at 29 °C, and seeds incubated with hydrogen peroxide at 29 °C, respectively.
