Tj1 elements and tRNA genes cluster in the centromeres of S. japonicus.
a The 3 chromosomes of S. pombe and S. japonicus are shown with colors that indicate regions of synteny. So, Sj, and Sp are abbreviations for Schizosaccharomyces octosporus, S. japonicus, and S. pombe, respectively. The center bar in each chromosome is colored: red for chromosome 1, blue for chromosome 2, and yellow for chromosome 3. Transposable elements are mapped as black vertical lines and short RNA species previously detected are shown as purple vertical lines . b Available contigs from the centromeres of S. japonicus are shown with colors that mark the positions of tRNA genes and different families of LTR-retrotransposons.
