Deskripsi
In this study, we sequenced the complete chloroplast genome of Dracaena cochinchinensis and used the data to assess its genomic resources. The complete chloroplast genome revealed a circular genome of 155,182 bp size with 37.5% GC content. The chloroplast genome is a typical quadripartite chloroplast structure with inverted repeats (26,507 bp) separated by small single copy (18,466 bp) and large single copy (83,702 bp) regions. De novo assembly and annotation showed the presence of 112 unique genes with 78 protein-coding genes, 30 tRNA genes, and four rRNA genes. We identified a total of 68 simple sequence repeat (SSR) markers in the chloroplast genome. A maximum-likelihood phylogenomic analysis showed that the position of D. cochinchinensi was on the base of Nolinoideae. Overall, the results of this study will contribute to better support of the evolution, molecular biology and conservation of D. cochinchinensi.
