Group II Intron-MediatedTrans-Splicing in the Gene-Rich Mitochondrial Genome of an Enigmatic Eukaryote,Diphylleia rotans

Although mitochondria have evolved from a single endosymbiotic event, present day mitochondria of diverse eukaryotes display a great range of genome structures, content and features. Group I and group II introns are two features that are distributed broadly but patchily in mitochondrial genomes across branches of the tree of eukaryotes. While group I intron-mediated trans -splicing has been reported from some lineages distantly related to each...
