Plastome structure and phylogeny of C.Y. Cheng (Gnetaceae, Gnetales).

This article describes the complete chloroplast genome of . The plastome was 114,795 bp in length, containing a large single copy region (66,103 bp) and a small single copy region (9438 bp), separated by two inverted repeat regions (19,627 bp). The genome lost all genes and contained 116 genes, including 68 protein-coding genes, 40 genes, and eight genes. The GC content was 33.3%, 12 genes all contained an intron, gene contained two introns while was a transpliced gene. Phylogenetic analysis using 61 concatenated protein-coding genes suggests that with the rest of other gnetophytes were sister to or nested within all conifers.
