Differences in lysine succinylation during the grafting process of Chinese hickory. a Number of DESPs during the grafting process of Chinese hickory. Enrichment analysis of DESPs in Chinese hickory during grafting process. Significantly enriched GO terms of DESPs concerning biological process (b) and molecular function (c). d Significantly enriched KEGG terms of DESPs. e Significantly enriched protein domains of DESPs. For hierarchical clustering, protein categories that were enriched in at least one of the clusters with a P-value < 0.05 were transformed by the x = −log10 (P-value) function. These x-values were z-transformed and clustered by one-way hierarchical clustering basing on the Euclidean distance. The quantifiable proteins in this study were divided into four quantitative categories according to their D7/D0 Ratio: Q1 (0 < D7/D0 Ratio < 1/1.5), Q2 (1/1.5 < D7/D0 Ratio < 1/1.3), Q3 (1.3 < D7/D0 Ratio < 1.5) and Q4 (D7/D0 Ratio > 1.5)
