Abstract
Elaeagnus ‘viridis’, an artificial hybrid of E. macrophylla (♂) Thunb. (1784) × E. pungens (♀) Thunb. (1784), is known for its economic and ecological value. In this study, we sequenced and assembled the whole chloroplast (cp) genome of E. ‘viridis’. The results showed that its cp genome was 152,284 bp long, showing a typical quadripartite structure and containing a large single-copy region (LSC, 82,299 bp), a small single-copy region (SSC, 18,239 bp), and a pair of inverted repeats (IRs, 51,746 bp). The cp genome contains 132 genes, including 86 protein-coding genes (PCGs), 38 tRNA genes, and 8 rRNA genes. Phylogenetic analysis based on 66 common PCGs revealed that E. ‘viridis’ is most closely related to its maternal parent E. pungens. The chloroplast genomic information reported in this study will shed some useful light for further genetic studies in the genus Elaeagnus.
