The complete mitochondrial genome of a wild-collected <i>Kappaphycus malesianus</i> (Solieriaceae, Rhodophyta)

<i>Kappaphycus malesianus</i> is a red seaweed farmed primarily for its carrageenan, a polysaccharide important in the food and pharmaceutical industries. Among the commercially cultivated <i>Kappaphycus</i> species, only <i>K. malesianus</i> has no mitogenome data available. Here, we assembled the mitochondrial genome of <i>K. malesianus</i> from next-generation sequencing data. The circular mitogenome consisted of 25,250 base pairs (bp) with a GC content of 30.25%. These values were comparable to previously sequenced solieriacean mitogenomes. Structural features, such as the stem-loop and hairpin, which were previously reported in other rhodophytes mitochondrial DNA, were also identified. The annotated genes (24 protein-coding genes, 24 tRNA genes, and 2 rRNA genes) were arranged in an order similar to the other available solieriacean mitogenomes. Lastly, phylogenetic analysis using 23 predicted protein domains showed the sister relationship of <i>K. malesianus</i> with other <i>Kappaphycus</i> species.
