Differential expression of haplotype-phased genes in various tissues of wild P. yedoensis. a Heat maps representing the expression of 562 maternal- and 576 paternal-phased genes, which are identified as differentially expressed genes in the mRNA-seq analysis, in different tissues. The normalized count values of a given gene from three independent biological replicates across all samples were used as a normalization factor. The vertical axes organize genes according to co-expression. The horizontal axes represent five tissues: leaf (L), petal (Pe), pistil (Pi), stamen (S), and berry (B). b Heat maps showing the differential expression of a selected category of genes related to development and secondary metabolite biosynthesis. The average normalized count values represent the relative expression across tissues. M maternal-phased genes, P paternal-phased genes
