Telotrons: spliceosomal introns composed of telomeric repeats
Spliceosomal intron numbers vary widely across eukaryotes, but the only established mechanism for large bursts of intron gain is the spread of transposable introner elements. We describe telotrons, spliceosomal introns composed predominantly of telomeric repeats. In a survey of 10,310 eukaryotic genome assemblies, we identified 7,008 introns with >85% telomeric repeat coverage and an additional…
