The complete plastome of Nyssa yunnanensis, a critically endangered tree species

Nyssa yunnanensis is a critically endangered species endemic to China. Here, we assembled and characterized the plastome of N. yunnanensis using Illumina paired-end data. The assembled plastome is 156,544 base pairs (bp) in length, containing a large single-copy (LSC) region of 86,056 bp, a small single-copy (SSC) region of 18,262 bp, and two inverted repeat (IR) regions of 26,113 bp. The plastome possesses total 125 genes, including 81 protein-coding genes, eight rRNA genes, and 36 tRNA genes. In addition, the overall GC-content of the whole plastome is 37.9%, while the corresponding values of the LSC, SSC, and IR regions are 36.0, 32.2, and 43.0%, respectively. Furthermore, phylogenetic analyses show that N. yunnanensis is closely related to the species of Camptotheca acuminata.
