Analysis of organellar genomes in brown algae reveals an independent introduction of similar foreign sequences into the mitochondrial genome
International audience Kelp species (Laminariales, Phaeophyceae) are globally widespread along temperate to Polar rocky coastal lines. Here we analyse the mitochondrial and chloroplast genomes of Laminaria rodriguezii, in comparison to the organellar genomes of other kelp species. We also provide th...
