Complete plastome sequence of Erythropalum scandens (Erythropalaceae), an edible and medicinally important liana in China

Abstract

Erythropalum scandens (Erythropalaceae, Santalales) is a large liana distributed in alluvial and riparian forests of Southeast Asia. Here we report and characterize the complete plastid genome sequence of E. scandens in an effort to provide genomic resources useful for developing its medicinal and edible value. The complete plastome is 156,154 bp in length and contains the typical structure and gene content of angiosperm plastomes, including two Inverted Repeat (IR) regions of 26,394 bp, a large single-copy (LSC) region of 84,799 bp and a small single-copy (SSC) region of 18,567 bp. The plastome contains 112 genes, consisting of 79 unique protein-coding genes, 29 unique tRNA genes and four unique rRNA genes. The overall A/T content in the plastome of E. scandens is 62.01%. Phylogenetic analyses were performed using the entire plastome, including genes, spacers and introns, which recovered E. scandens as sister to remaining Santalales with complete plastome sequences.
