title: The mitochondrial genome of Grateloupia taiwanensis (Halymeniaceae, Rhodophyta) and comparative mitochondrial genomics of red algae.
abstract: Although red algae are economically highly valuable for their gelatinous cell wall compounds as well as being integral parts of marine benthic habitats, very little genome data are currently available. We present mitochondrial genome sequence data from the red alga Grateloupia taiwanensis S.-M. Lin & H.-Y. Liang. Comprising 28,906 nucleotide positions, the mitochondrial genome contig contains 25 protein-coding genes and 24 transfer RNA genes. It is highly similar to other red algal genomes in gene content as well as overall structure. An intron in the cox1 gene was found to be shared by G. taiwanensis and Grateloupia angusta (Okamura) S. Kawaguchi & H. W. Wang. We also used whole-genome alignments to compare G. taiwanensis to different groups of red algae, and these results are consistent with the currently accepted phylogeny of Rhodophyta.
