Comparative Chloroplast Genomics of Corydalis Species (Papaveraceae): Evolutionary Perspectives on Their Unusual Large Scale Rearrangements.

ABSTRACT: The chloroplast genome (plastome) of angiosperms (particularly photosynthetic members) is generally highly conserved, although structural rearrangements have been reported in a few lineages. In this study, we revealed Corydalis to be another unusual lineage with extensive large-scale plastome rearrangements. In the four newly sequenced Corydalis plastomes that represent all the three subgenera of Corydalis, we detected (1) two independent relocations of the same five genes (trnV-UAC-rbcL) from the typically posterior part of the large single-copy (LSC) region to the front, downstream of either the atpH gene in Corydalis saxicola or the trnK-UUU gene in both Corydalis davidii and Corydalis hsiaowutaishanensis; (2) relocat
