The complete chloroplast genome and phylogenetic analysis of Elaeagnus oldhamii (Elaeagnaceae) from Fujian, southeastern China

Abstract

AbstractElaeagnus oldhamii Maximowicz 1870 is an important medicinal plant mainly distributing in the southeastern coastal region of China. However, the complete chloroplast genome of E. oldhamii has never been studied at present. We obtained the complete chloroplast genome of E. oldhamii, which was 152,283 bp in length, with a typical quadripartite structure that includes a large single-copy region of 82,229 bp, a small single-copy region of 18,256 bp, and 2 inverted repeat (IR) regions of 25,899 bp. The genome contained 128 unique genes with a GC content of 37%, including 83 protein-coding genes, 37 tRNAs, and 8 rRNAs. Phylogenetic analysis suggested that E. oldhamii was closely related to E. glabra and E. macrophylla.
