Seven Complete Chloroplast Genomes from Symplocos: Genome Organization and Comparative Analysis
In the present study, chloroplast genome sequences of four species of Symplocos (S. chinensis for. pilosa, S. prunifolia, S. coreana, and S. tanakana) from South Korea were obtained by Ion Torrent sequencing and compared with the sequences of three previously reported Symplocos chloroplast genomes from different species. The length of the Symplocos chloroplast genome ranged from 156,961 to 157,365 bp. Overall, 132 genes including 87 functional genes, 37 tRNA genes, and eight rRNA genes were identified in all Symplocos chloroplast genomes. The gene order and contents were highly similar across the seven species. The coding regions were more conserved than the non-coding regions, and the large single-copy and small single-copy regions were less conserved than the inverted repeat regions. We identified five new hotspot regions (rbcL, ycf4, psaJ, rpl22, and ycf1) that can be used as barcodes or species-specific Symplocos molecular markers. These four novel chloroplast genomes provide basic information on the plastid genome of Symplocos and enable better taxonomic characterization of this genus.
