Chromosome-level features of the Okinawan O. dioica genome. a Visualization of sequence properties across chromosomes in the OKI2018_I69 assembly. For each chromosome, 50 kbp windows of GC (orange), Nanopore sequence coverage (blue), the percent of nucleotides masked by RepeatMasker (purple), and the number of genes (yellow) are indicated. Differences in these sequence properties occur near predicted sites of centromeres and telomeres, as well as between the short and long arms of each non-sex-specific chromosome. Telomeres and gaps in the assembly are indicated with black and grey rectangles, respectively. b Long and short chromosome arms exhibit significant differences sequence properties, including GC content, repetitive sequence content, and the number of restriction sites recognized by the DpnII enzyme used to generate the Hi-C library
