 A potential new pattern of accD genes in cactus plastomes. We performed multiple alignments of amino acid sequences of accD genes from Solanum tuberosum (NC_008096.2), Arabidopsis thaliana (NC_000932.1), Portulaca oleracea (NC_036236.1) and cactus plastomes. The downstream region of the accD gene is highly conserved in these species and contains five conserved motifs, of which motifI contains the carboxyl-biotin binding sites and motifII contains the potential catalytic site. In the figure, 5 conserved motifs are shown at the top, while the multisequence alignment diagram is shown at the bottom. The gray ribbon represents homologous sequences, among which 5 conserved motifs are highlighted with different colors. The downstream domain of the accD gene is conserved, but in cactus species, the upstream region has more repeats and is extremely nonconserved between species
