Alignment of the analyzed region of plastid ndhB genes. Positions identical to the M. polymorpha (Mar) reference sequence are denoted by dots. The amino acid sequence derived from the Marchantia ndhB gene is given below using the one letter code. Nucleotides subject to RNA editing (sites I–XVII) are marked by bold letters. The insertion site of the single group II intron interrupting the ndhB reading frame in all species is located between positions 321 and 322. Abbreviations and database accession numbers for the nucleotide sequences are as follows: Zea (Zea mays, X86563X86563), Ory (Oryza sativa, X15901X15901), Hor (Hordeum vulgare, X90650X90650), Nar (Narcissus pseudonarcissus, Z80865Z80865), Aco (Acorus calamus, Z80856Z80856), Nic (Nicotiana tabacum, Z00044Z00044), Dau (Daucus carota, Z80859Z80859), Pis (Pisum sativum, Z80872Z80872), Pha (Phaseolus vulgaris, Z80873Z80873), Ham (Hamamelis mollis, Z80862Z80862), Nym (Nymphaea caerula, Z80866Z80866), Mag (Magnolia grandiflora, Z80864Z80864), Cer (Ceratophyllum demersum, Z80857Z80857), Cry (Cryptomeria japonica, Z80858Z80858), Thu (Thujopsis dolabrata, Z80870Z80870), Gin (Ginkgo biloba, Z80861Z80861), Dio (Dioon edule, Z80860Z80860), Osm (Osmunda claytoniana, Z80867Z80867), Psi (Psilotum nudum, Z80871Z80871), Lyc (Lycopodium obscurum, Z80863Z80863), Sph (Sphagnum palustre, Z80869Z80869), Pel (Pellia epiphylla, Z80868Z80868), and Baz (Bazzania trilobata, Z80874Z80874).
