Fig 2. Distribution of mitochondrial ribosomal protein genes in Alismatales mitogenomes.

Blank boxes indicate absence of a gene from the mitogenome. Dark grey boxes indicate presence of a gene assumed to be functional. Light grey boxes and Ψ indicates a pseudogene or fragment of gene in the mitogenome. N indicates presence of a gene annotated as of mitochondrial origin in the nuclear genome of Zostera marina. (n) indicates likely presence of a gene in the nuclear genome of Zostera marina, though not annotated as of mitochondrial origin. *Zostera noltii has the same mitochondrial genes, but the potential nuclear location of genes is unknown.
