Divergent mega-NUMT mimicking entirely functional complete mitochondrial genome

Using long read sequencing, we report here a NUMT (nuclear fragment of mitochondrial origin) in a sawfly species Euura vittata that contains the entire coding region with all the genes in the same order as in the mitochondrion. The NUMT is 3.2% different from the mitochondrial sequence (4.1% divergence for COI barcode region), yet appears entirely functional when assuming mitochondrial genetic…

We haven't written up this one. bioRxiv has the full story — the link below goes straight to it.
