Project description:Syzygium samarangense (Blume) Merr. et Perry, 1938, commonly known as wax apple, is a Myrtaceae species that is known for its unique fruit shape, flavorful and colorful fruits, medicinal value and increasing economic relevance. In this study, we reported the complete chloroplast genome sequence of S. samarangense. The complete genome is 159,109 bp in length with a quadripartite structure containing two single copy regions, a Large Single Copy region (LSC, 88,155 bp) and a Small Single Copy region (SSC, 18,796 bp) separated by Inverted Repeat regions (IRs, 26,079 bp). The GC content was 37.0%. It encoded 126 genes, including 81 protein-coding genes, 37 transfer RNA genes, and 8 ribosomal RNA genes. The phylogenetic relationships of 20 species inferred that all Syzygium species formed a single cluster belonging to Syzygieae tribe. Our results offer insights into the evolutionary relationship of S. samarangense within Myrtaceae, indicating a closer relationship between S. samarangense and S. forrestii.
Project description:Syzygium samarangense is an important fruit of Myrtaceae family and commercially planted in tropical areas of the world. Chloroplast genome sequences play a significant role in the development of molecular markers in plant phylogenetic and population genetic studies. In this study, we report the complete chloroplast genome sequence of S. samarangense for the first time (accession number of MH371141). The chloroplast genome is 159,109 bp long and includes 113 genes. Its LSC, SSC and IR regions are 88,533, 18,882, and 25,847 bp long, respectively. Phylogenetic tree analysis exhibited that S. samarangense was clustered with other Myrtaceae species with 100% bootstrap values.
