RNA editing affects the secondary structure of trnM transcript in moth orchid. a The nucleotide sequences of plastid trnM (cau) gene from nine species of seed plants were multiple aligned by using LaserGene (DNAstar, USA). RNA editing at the indicated position is converted from C to U in moth orchid. Orchid, Phalaenopsis aphrodite; Maize, Zea mays; Rice, Oryza sativa; Coconut, Cocos nucifera; Arabidopsis, Arabidopsis thaliana; Tobacco, Nicotiana tabacum; Amborella, Amborella trichopoda; Pine, Pinus thunbergi, Cycas, Cycas taitungensis. b The predicted tRNA secondary structures formed by the unedited and edited trnM transcripts, by using the tRNAscan-SE 1.21 algorithm. The edited and unedited nucleotides are indicated by arrows
