Fig. 1. Features of the C. reinhardtii CC-2937 GEVE and its insertion site.

(A) Line plots representing the tandem repeats (black) and GC fraction (yellow) of the viral contig_536. The TIRs flanking the GEVE are marked and shown with arrows. Regions in the contig with viral signatures are represented by ViralRecall scores >0 (red), while eukaryotic regions represent scores <0 (blue). Synteny blocks between the viral contig and chromosome 15 of the reference genome (C. reinhardtii CC-4532 v6) are shown in gray. The tandem repeats and GC fraction tracks are also shown for this chromosome at the bottom. (B) Alignment of five independent copies of the interspersed repetitive element in which the GEVE is integrated. Only the ends of the TIRs are represented and the 6 bp TSD is highlighted by a box. (C) Integration sites of two putative GEVE relics on chromosomes 16 and 7. The TIRs and TSDs of the insertions in CC- 2937 are shown relative to three divergent strains that do not carry the insertions.
