Figure 1.

Genomic distribution of arrays of TRs on T. castaneum assembled chromosomes (CH1–CH10). Vertical bars represent short arrays (<5 monomers/array, upper line) and long arrays (≥5 monomers/array, lower line). The actual number of arrays per Mb for short and long arrays is indicated above each chromosome. Red dots correspond to centromeric TCAST satDNA found in the assembled genome. Horizontal bar represents putative euchromatin (white) and heterochromatin (HighA domain, grey) regions as identified in Wang et al.²⁸ Locations of the 300 kb placeholders were included to define uncaptured gaps (yellow). Red triangles indicate assumed position of the centromere and large blocks of centromeric heterochromatin based on our FISH analyses (Fig. 4), chromosome banding²⁹ and HighA domain (putative heterochromatin) defined in Wang et al.²⁸
