The first plastid genome of a filamentous taxon ‘Bangia’ sp. OUCPT-01 in the Bangiales
Red algae are important primary photosynthetic organisms. The Bangiales comprise a morphologically diverse order of red algae. Until now, complete plastid genomes of the Bangiales were only mapped for foliose species. To date, no filamentous plastomes have been published. The aim of this study was t...

description | Red algae are important primary photosynthetic organisms. The Bangiales comprise a morphologically diverse order of red algae. Until now, complete plastid genomes of the Bangiales were only mapped for foliose species. To date, no filamentous plastomes have been published. The aim of this study was to determine and analyze the complete plastid genome of the filamentous marine species ‘Bangia’ sp. OUCPT-01. It is a circular molecule, 196,913 bps in length with a guanine-cytosine (GC) content of 33.5%. It has a quadripartite structure with two single copy regions separated by two direct non-identical repeats. It has 205 protein-coding genes, 37 tRNAs, and 6 rRNAs. Therefore, it has a high coding capacity and is highly similar to other Bangiales species in terms of content and structure. In particular, it reveals that the genera in the Bangiales have highly conserved gene content and plastome synteny. This plastome and existing data provide insights into the phylogenetic relationships among the Bangiales genera of the Rhodophyta. According to its plastid- and mitochondrial genomes, ‘Bangia 2′ is a sister group to Porphyra. However, the position of Wildemania schizophylla in the Bangiales is still controversial. Our results show that the Bangiales divergence time was ~225 million years ago. |
