Complete mitochondrial genome of the brown alga <i>Sargassum fusiforme</i> (Sargassaceae, Phaeophyceae): genome architecture and taxonomic consideration Feng Liu Shaojun Pang Minbo Luo 10.6084/m9.figshare.1569199.v1 https://tandf.figshare.com/articles/journal_contribution/Complete_mitochondrial_genome_of_the_brown_alga_i_Sargassum_fusiforme_i_Sargassaceae_Phaeophyceae_genome_architecture_and_taxonomic_consideration/1569199 <div><p></p><p><i>Sargassum fusiforme</i> (Harvey) Setchell (=<i>Hizikia fusiformis</i> (Harvey) Okamura) is one of the most important economic seaweeds for mariculture in China. In this study, we present the complete mitochondrial genome of <i>S. fusiforme</i>. The genome is 34,696 bp in length with circular organization, encoding the standard set of three ribosomal RNA genes (rRNA), 25 transfer RNA genes (tRNA), 35 protein‐coding genes, and two conserved open reading frames (ORFs). Its total AT content is 62.47%, lower than other brown algae except <i>Pylaiella littoralis</i>. The mitogenome carries 1571 bp of intergenic region constituting 4.53% of the genome, and 13 pairs of overlapping genes with the overlap size from 1 to 90 bp. The phylogenetic analyses based on 35 protein‐coding genes reveal that <i>S. fusiforme</i> has a closer evolutionary relationship with <i>Sargassum muticum</i> than <i>Sargassum horneri</i>, indicating <i>Hizikia</i> are not distinct evolutionary entity and should be reduced to synonymy with <i>Sargassum</i>.</p></div> 2014-07-03 00:00:00 Sargassum horneri RNA genes harvey intergenic region protein Sargassum muticum overlap size mitochondrial genome Phylogenetic analyses bp Complete Mitochondrial Genome reading frames orf 13 pairs Hizikia taxonomic consideration Sargassum fusiforme alga Sargassum fusiforme Pylaiella littoralis
