Kiwifruit protein–protein interaction network created by STRING 9.0. Protein-protein interactions are presented for identified kiwifruit proteins undergoing ripening inhibition by 1-MCP and O₃ (a) or ripening induction by exogenous ethylene (b). Analysis parameters used were Arabidopsis thaliana species and 0.4 confidence level. Lines with different colors represent the different types of evidence used for the predicted associations: gene fusion (red), neighborhood (green), co-occurrence across genomes (blue), co-expression (black), experimental (purple), association in curated databases (light blue), or co-mentioned in PubMed abstracts (yellow). Six groups of protein nodes that are highly interacting are marked with dotted lines and include proteins associated with energy, protein destination/storage, transporters, signal transduction, disease/defence and secondary metabolism functional categories
