The First Complete Mitogenome Characterization of Brown Alga <i>Dictyota coriacea</i> (Phaeophyceae, Heterokontophyta) and Its Phylogenetic Analysis.

ABSTRACT: Brown algae (Phaeophyceae) play vital ecological roles in marine ecosystems and are important models for studying organelle genome evolution. Despite their significance, mitogenome data for many taxa remain limited. In this study, we present the complete mitogenome sequence of Dictyota coriacea, a representative brown alga from the family Dictyotaceae (Phaeophyceae). The circular mitogenome of D. coriacea is 31,573 bp in length and encodes 62 genes, including 35 protein-coding genes (PCGs; including uncharacterized open reading frame (orf109)), 25 tRNAs, and 3 rRNAs. The overall gene content and arrangement are largely conserved and consistent with other Dictyotaceae species. However, minor but notable genomic variations were observed, such as gene overlaps, variation
