"The psbA-trnH intergenic region is among the most variable regions in the angiosperm chloroplast genome. It is a popular tool for plant population genetics and species level phylogenetics and has been proposed as suitable for DNA barcoding studies. This region contains two parts differing in their evolutionary conservation: 1) the psbA 3\u2019UTR (untranslated region) and 2) the psbA-trnH intergenic non-transcribed spacer. We compared the sequence and RNA secondary structure of the psbA 3' UTR across angiosperms and found consensus motifs corresponding to the stem portions of the RNA stem-loop structures and a consensus TTAGTGTATA box. The psbA-trnH spacer exhibited patterns explicable by the independent evolution of large inversions in the psbA 3\u2019UTR and mutational hot spots in the remaining portion of the psbA-trnH spacer.
