Pyrus pashia is a deciduous fruiting tree species of high commercial, scientific, nutritional and therapeutic values. Many of its wild populations are in danger, and need urgent conservation. To contribute to such efforts, its complete chloroplast genome was assembled from high-throughput Illumina sequencing data. The circular genome is 160,153 bp long, and displays a typical quadripartite structure of the large (LSC, 88,129 bp) and small (SSC, 19,252 bp) single-copy regions, separated by a pair of inverted repeat regions (IRs, 26,386 bp each). It harbors 112 gene species, including 78 protein-coding, 30 transfer RNA and 4 ribosomal RNA gene species. Being similar to many other confamilial taxa, it has a biased base composition (31.35% A, 18.63% C, 17.93% G and 32.09% T) with an overall A+T content of 63.44%. Phylogenetic analysis suggested that P. pashia was more closely related to its congeners than to the other confamilial taxa with sequenced chloroplast genomes.
