Gene-based pan-genome of Actinidia. (a) Composition of the pan-genome. The histogram shows the number of gene families in the 15 assemblies with different frequencies. Pie shows the proportion of core, softcore, dispensable, and cloud genes. b The core, softcore, dispensable, and cloud gene numbers in each assembly. c Proportions of genes with and without InterPro domains in core, soft core, dispensable, and cloud genes. The distribution of gene lengths (d), exon numbers (e) and nucleotide diversity (f) of core, softcore and dispensable genes. ***p < 0.001, Student’s t test. g Expression levels of core, softcore and dispensable genes in A. eriantha at different tissues. h GO enrichment analysis of softcore and dispensable genes
