aThe taxa newly examined in this study are denoted by asterisks. bIntron-encoded genes and freestanding ORFs not usually found in green plant chloroplast genomes were not considered. Duplicated genes were counted only once. cNumbers of group I (GI) and group II (GII) introns are given. dNonoverlapping repeat elements were mapped on each genome with RepeatMasker using as input sequences the repeats of at least 30 bp identified with REPuter. eThis value is based on the re-annotated version of Leliaert & Lopez-Bautista35. fThis value includes four genes with frameshift mutations (rpoB, rpoC1, ycf20 and ycf47).
