Mitochondrial and plastid genome analysis of the heteromorphic red alga Mastocarpus papillatus (C. Agardh) Kützing (Phyllophoraceae, Rhodophyta) reveals two characteristic florideophyte organellar genomes.

Analysis of the marine red algal species Mastocarpus papillatus (C. Agardh) Kützing using paired-end 36 bp Illumina sequences resulted in the assembly of its complete mitochondrial and plastid genomes. The mitogenome is 25,906 bp in length and contains 50 genes, and the plastid genome is 184,382 bp with 234 genes. The mitochondrial and plastid genomes show high gene synteny with published Florideophyceae.
