  1. The AT-rich repeat domains are associated with the sites of etoposide-mediated Topo-II cleavage on T. brucei chromosomes 1-8 (Additional data file 4 and summarized in Figure 6). The flanking ORFs are those immediately adjacent to the repeat array. *BAC clone RPCI93-3K10 contains a large number of 120 bp repeats that span up to 30 kb (GeneDB). This region has not yet been closed. The repeat array contains a gap of unknown size. There are 1.5 copies of this repeat next to a gap in the chromosome 8 sequence at position 2,233,104 bp. The unresolved array is estimated to be 5-9 kb (GeneDB). §Several chromosome 9 reads (approximately 700 bp) contain these repeats (for example, tryp_IXb-344h12.p1c, GeneDB). A 10 kb contig tryp_X-275g09.p1c (Tb10.v4.0130) and several chromosome 10 reads (approximately 700 bp) contain these repeats (for example, tryp_X-429d08.q1c, GeneDB). ¥A 14 kb contig tryp_XI-974h12.q1k (Tb11.1750) and several chromosome 11 reads (approximately 900 bp) contain these repeats (for example, tryp_XI-991b09.q1k, GeneDB).
