Fig. 1: Gene expression and chromatin accessibility associated with the four subgenomes (A, B, C, D) in strawberry.

a Percentage of expressed and non-expressed genes in the four subgenomes. Subgenome A has a lower percentage of non-expressed genes and a higher percentage of expressed genes (A vs. B: p = 2.4e−6; A vs. C: p = 1.2e−4; A vs. D: p = 1.8e–2, two-sided chi-square test). b A total number of MHSs in each subgenome. c Average number of MHSs per gene in each subgenome (n_A = 27,398, n_B = 25,461, n_C = 24,505, n_D = 23,911). d Average MHS length per gene in each subgenome (n_A = 27,398, n_B = 25,461, n_C = 24,505, n_D = 23,911). The lower and upper boundaries of each box indicate 25th and 75th percentile, the center line indicates the median, and the whiskers extend to 1.5× IQR. In (c, d), the total number of MHSs and MHS length were normalized in the four subgenomes by dividing to the total number of genes from each subgenome. Means that do not share a letter are significantly different (p < 0.01, one-way ANOVA with Games-Howell post-hoc test). Source data are provided as a Source Data file.
