Abstract

Elaeagnus bambusetorum Hand.-Mazz. is a rare plant from China in the Elaeagnaceae family. In this study, we sequenced its complete chloroplast genome. The whole chloroplast genome was 152,265 bp in length, containing a pair of inverted repeats of 25,897 bp, separated by large single copy and small single copy regions of 82,291 bp and 18,180 bp, respectively. The complete genome contained 113 genes, including 79 protein-coding genes, 30 tRNA genes, and 4 rRNA genes. The overall GC content was 37.1%. Phylogenetic analysis using the whole chloroplast genome revealed that E. bambusetorum is sister to E. loureirii and E. conferta. Our study provides valuable insights into the genetic information of E. bambusetorum, which may have important implications for species conservation.
