Fig. 1

Sample alignments showing the consensus initiation codon (cic) and subsequent translation products for MatK in orchids. (a) Nucleotide alignment of various orchid species and the non-orchid monocot species Asparagus aethiopicus, Hordeum vulgare, Saccharum officinarum and Oryza sativa. Asterisks next to species name indicate those noted in GenBank to contain matK as a pseudogene. Black arrow indicates cic used by other monocots and angiosperms for MatK expression. (b) Translated MatK amino acid sequence using the cic. Asterisk in translated amino acid sequence indicates stop codons in the MatK reading frame. Gray shadowing indicates highly conserved sequence among all taxa in the alignment, lighter gray indicates less conserved sequence, white background indicates a lack of conserved sequence. Note: gaps in nucleotide and amino acid alignment differ in relative position due to indel in Palmorchis trilobulata
