Abstract

The chloroplast genome sequence of an endangered relict tree species endemic to China, Emmenopterys henryi, was determined based on the Illumina data. The chloroplast genome of E. henryis was sequenced (155,379 in length, GenBank accession number KY273445). It contains 62.36% A+T base pairs and consists of a pair of inverted repeats (IRs, 25,790 bp) separated by the large single-copy (LSC, 85,554 bp) and small single-copy (SSC, 18,245 bp) regions. The chloroplast genome contains 132 unique genes, including 87 protein-coding genes, 37 transfer RNA genes and 8 ribosomal RNA genes, respectively. The phylogenetic analysis based on chloroplast genomes indicates that E. Henryi is most closely related to coffea arabica and coffea canephora.
