Relationship of COs sites to genome and chromatin features in male and female meioses. a Position of COs relative to TEs and protein coding genes. b Position of COs in the 5′ and 3′ regions of genes. c DNA methylation patterns around CO sites at CG, CHG, and CHH sites. d H3K4me3 levels of CO sites in male and female meioses. e Nucleosome occupancy of CO sites in male and female meioses measured using micrococcal nuclease sensitivity. f Boxplot showing transcription levels of CO-containing genes in male meiocytes and seedlings. Center lines of boxes represent median expression levels, bounds of boxes designate expression levels of the first (Q1) and third (Q3) quartiles from top, lower whiskers are Q1 – 1.5 × IQR, and upper whiskers are Q3 – 1.5 × IQR, where IQR = Q3 – Q1
