I love mite mt-tRNAs! I did some tRNA-seq on spider mites, and it was the first place I found this sense/antisense expression (+ some crazy short tRNAs). But I could still find all 22 tRNAs. With the mealys, it looks like this process has gone to replacement. Mirror expression -> gene loss

Although tRNA structure is one of the most conserved and recognizable shapes in molecular biology, aberrant tRNAs are frequently found in the mitochondrial genomes of metazoans. The extremely degenerate structures of several mitochondrial tRNAs ...
