Figure 6From: Complete chloroplast genome sequence of a tree fern Alsophila spinulosa: insights into evolutionary changes in fern chloroplast genomesTwo hypothetical pathways to explain rearrangement between rpoB and psbZ. Genes are represented by boxes, the colors of which are consistent with Figure 3. *In Angiopteris evecta ycf66 has an intact ORF, but in Alsophila spinulosa it is a pseudogene.Back to article page
