Complete chloroplast genome of Syzygium glomeratum (Myrtaceae) and phylogenetic analysis

Syzygium glomeratum (Lam.) DC., known as “Tram Tron” in Vietnam, is an evergreen tree known for its medicinal properties. To understand the genomic and evolutionary basis of this plant, we sequenced and assembled the complete chloroplast genome of S. glomeratum for the first time, using the Illumina platform. The complete chloroplast of S. glomeratum was 158,469 bp in length and contained a large single-copy region (87,962 bp) and a small single-copy region (18,391 bp) separated by inverted repeat regions (26,058 bp). The genome encoded 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes. A phylogenetic analysis of 42 Syzygium species revealed significant insight into their evolutionary relationships, indicating a closer relationship between S. glomeratum and its sister group (S. cinereum and S. claviflorum). In conclusion, our results provide genomic information pertaining to the chloroplast genome in S. glomeratum, which is also genetic information useful for further study of biodiversity, conservation, and evolutionary biology.
