Deskripsi

We assembled and characterized the complete chloroplast genome sequence of Silvianthus bracteatus to investigate its phylogenetic position. With a total length of 155,125 bp, the plastome comprised of a large single-copy (LSC) region of 86,054 bp, a small single-copy (SSC) region of 17,625 bp, and two inverted repeat (IR) regions of 25,723 bp. The overall percentage of GC content was 37.9. The new sequence comprised of total 136 genes, including 88 protein-coding genes, 8 ribosomal RNA genes, and 40 tRNA genes. In these genes, eight genes contained one intron and two genes contained two introns. Phylogenetic analysis showed that S. bracteatus was close to the Oleaceae.
