摘要Dictyotophycidae is a subclass of brown algae containing 395 species that are distributed worldwide. A complete plastid (chloroplast) genome (ptDNA or cpDNA) had not previously been sequenced from this group. In this study, the complete plastid genome of Dictyopteris divaricata (Okamura) Okamura (Dictyotales, Phaeophyceae) was characterized and compared to other brown algal ptDNAs. This plastid genome was 126,099 bp in size with two inverted repeats (IRs) of 6026 bp. The D. divaricata IRs contained rpl21, making its IRs larger than representatives from the orders Fucales and Laminariales, but was smaller than that from Ectocarpales. The G + C content of D. divaricata (31.19%) was the highest of the known ptDNAs of brown algae (28.94-31.05%). Two protein-coding genes, rbcR and rpl32, were present in ptDNAs of Laminariales, Ectocarpales (Ectocarpus siliculosus), and Fucales (LEF) but were absent in D. divaricata. Reduced intergenic space (13.11%) and eight pairs of overlapping genes in D. divaricata ptDNA made it the most compact plastid genome in brown algae so far. The architecture of D. divaricata ptDNA showed higher similarity to that of Laminariales compared with Fucales and Ectocarpales. The difference in general features, gene content, and architecture among the ptDNAs of D. divaricata and LEF clade revealed the diversity and evolutionary trends of plastid genomes in brown algae.
