aThe trnM(cau) gene situated in the large tRNA region in B. hypnoides showed similarity (blastn E value < 2e-10) with land plant nuclear encoded tRNA-Met initiator (Met-tRNA-i) genes.
Numbers indicate gene copy. An asterisks indicates that the gene or gene copy is situated in the large tRNA region in B. hypnoides (Additional file 2). B. hyp = Bryopsis hypnoides, B. plu = B. plumosa, T. exp = Tydemania expeditiones, P. aki = Pseudendoclonium akinetum, O. vir = Oltmannsiellopsis viridis.
