Fig. 5: Assembly of 177 bp-containing sub-megabase T. brucei chromosomes that harbour diverse transcribed genes.

A A diagrammatic representation of two distinct forms of Nanopore contigs, one type housing a telomeric VSG BES (orange) and each containing 177 bp repeats characteristic of sub-megabase chromosomes of T. brucei. B RNA-seq mapping to eight sub-megabase chromosome Nanopore contigs (tigs). C Circos plots showing correspondence between the sub-megabase chromosome Nanopore contigs and many previously unassigned unitigs; grey ribbons represent simple overlaps, and black ribbons represent multiple overlaps within a region. D Gene content of the novel, smaller chromosomes: only the most abundant predicted gene types are detailed (total numbers are shown), amongst which the range of orthology groups (OG6) predicted amongst hypothetical genes by OrthoMCL is illustrated.
