Mitochondrial DNA B Resour. 2022 Jun 10;7(6):977-979. doi: 10.1080/23802359.2022.2080022. eCollection 2022.

Abstract

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.

Keywords: Syzygium samarangense; chloroplast genome; phylogenetic relation; wax apple.
