Chloroplast genome of the invasive Pyrus calleryana

<p>The complete chloroplast genome of Pyrus calleryana (BioSample SAMC013142) was developed by de novo assembly from whole-genome sequencing data. Reference-guided (P.<b> </b>phaeocarpa<b>) </b>read<b> </b>mapping and assembly were followed by annotation and phylogenetic comparisons. The Pyrus calleryana chloroplast genome of 159,965 bp in length (36,56% of GC content) represents a classical quadripartite architecture, with two inverted repeats regions (IRs; each 26,392 bp in length) separating the large single-copy region (LSC; 87,942 bp) and the small single-copy region (SSC; 19.239 bp). In total, 115 unique genes were predicted and annotated in that genome, including 81 protein coding genes, 30 tRNA coding genes, and 4 rRNA coding genes. Phylogenetic analyses based on the whole chloroplast genome sequences places the P. calleryana among other Rosaceae plants, specifically among the Asian species of Pyrus.</p>
