    • Giant group I intron in a mitochondrial genome is removed by RNA back-splicing 

      Chi, Sylvia Ighem; Dahl, Mikael; Emblem, Åse; Johansen, Steinar (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-06-01)
      <p><i>Background - </i>The mitochondrial genomes of mushroom corals (Corallimorpharia) are remarkable for harboring two complex group I introns; ND5-717 and COI-884. How these autocatalytic RNA elements interfere with mitochondrial RNA processing is currently not known. Here, we report experimental support for unconventional processing events of ND5-717 containing RNA. <p><i>Results - </i>We obtained ...

    • The Mitochondrial Genome of the Sea Anemone Stichodactyla haddoni Reveals Catalytic Introns, Insertion-Like Element, and Unexpected Phylogeny 

      Johansen, Steinar Daae; Chi, Sylvia Ighem; Dubin, Arseny; Jørgensen, Tor Erik (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-28)
      A hallmark of sea anemone mitochondrial genomes (mitogenomes) is the presence of complex catalytic group I introns. Here, we report the complete mitogenome and corresponding transcriptome of the carpet sea anemone Stichodactyla haddoni (family Stichodactylidae). The mitogenome is vertebrate-like in size, organization, and gene content. Two mitochondrial genes encoding NADH dehydrogenase subunit 5 ...
