Fig. 3From: Alternative translation initiation codons for the plastid maturase MatK: unraveling the pseudogene misconception in the OrchidaceaeAlignment of 5’UTR matK sequence to determine possible Shine-Dalgarno (SD) elements for ribosome binding. Asterisk indicates species noted in GenBank to contain matK as a pseudogene. Gray arrow shows hypothesized alternative out-of-frame initiation codon. Black arrow indicates consensus initiation codon used by other monocots and angiosperms for matK expression. SD-like region is boxed. SD consensus sequence is shown at bottom of alignment. Gray shadowing indicates highly conserved sequence among all taxa in the alignment, white background indicates a lack of conserved sequenceBack to article page
