Abstract:
Illigera grandiflora, a kind of traditional medicinal liana, belongs to the Illigera Blume of the Hernandiaceae. In this study, we reported the characteristics of complete plastome for I. grandiflora. Its total plastome was 156,138 bp in length, comprising a large single-copy region(LSC) of 84,931 bp, a small single-copy region (SSC) of 18,544 bp, and a pair of inverted repeat (IR) regions of 26,549 bp. The overall GC content was 39.16% (LSC, 37.77%; SSC, 33.89%; IR, 43.21%). The plastome encoded 134 genes, including 83 protein-coding genes, 42 transfer RNA genes, and 10 ribosomal RNA genes. The relationships in our phylogeny showed that the two Illigera species are located in the same clade, with Hernandia nymphaeifolia being the next sister group, followed by Wilkiea huegeliana.
