Identification of the centromeric regions via repetitive sequence analysis. (a) Frequency distribution of repetitive sequences across the genome binned by sequence length (period) in base pairs (bp). The horizontal axis represents the period of repetitive sequences, and the vertical axis represents the number of occurrences in each period. (b) Logarithmic scale representation of data shown in (a). The horizontal axis represents the period of repetitive sequences in bp, and the vertical axis represents the log-transformed count of occurrences for each period. (c) Distribution of genes, non-coding RNAs (ncRNA), LTR elements (Gypsy and Copia), LINE, SINE, and specific lengths of repetitive sequences considered to constitute centromeric structures. The horizontal axis represents the chromosomal position, and the vertical axis indicates the presence of these elements. Notably, repetitive sequences associated with centromeric structures lacked gene-rich regions, indicating putative centromeric regions.
