The complete chloroplast genome sequence of Buxus megistophylla Levl. (Buxaceae Dumort.)

Buxus megistophylla Levl. is one of the most common green horticultural plants in the city presently. Here, we assembled and annotated the complete chloroplast (cp) genome of B. megistophylla. The whole length of the genome is 157,611 bp and encodes a total of 124 genes, which contains 89 protein-coding genes, 31 transfer RNA (tRNA) genes, and four ribosomal RNA (rRNA) genes. Phylogenetic tree analysis showed that B. megistophylla is separated from two other species of the same family, but these three species, clustered in one clade, are relatively closer to each other compared to the species in other families. This cp genome sequencing and phylogenetic analysis offer genetic background for conservation and may contribute to further evolutionary studies of this species.
