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

ABSTRACT: This article describes the complete chloroplast genome of Gnetum luofuense. The G. luofense 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 ndh genes and contained 116 genes, including 68 protein-coding genes, 40 tRNA genes, and eight rRNA genes. The GC content was 33.3%, 12 genes all contained an intron, ycf3 gene contained two introns while rps12 was a transpliced gene. Phylogenetic analysis using 61 concatenated protein-coding genes suggests that G. luofuense with the rest of other gnetophytes were sister to or nested within all conifers.
