The complete chloroplast genome sequence of Pyrus phaeocarpa Rehd.

Abstract

Pyrus phaeocarpa Rehd. belongs to the Pyrus genus (Rosaceae) with high commercial value in China. Many trees in the wild have been destroyed affected by human activities and needed to be protection urgently. In this study, we reported the complete chloroplast genome sequence of P. phaeocarpa using Illumina sequencing technology. The complete chloroplast genome of P. phaeocarpa was 160,203 bp in length, containing a large single copy (LSC, 88,200 bp), a small single copy (SSC, 19,231 bp), and a pair of inverted repeats (IRs, 26,385 bp). The chloroplast genome GC content was 36.54%, contained 113 unique genes, including 30 tRNA, four rRNA, and 79 protein-coding genes. Phylogenetic analysis revealed that P. phaeocarpa was close to P. pashia, P. pyrifolia, and P. ussuriensis, provided strong support for the relationship of Pyrus. ARTICLE HISTORY

Chloroplast genome of the invasive Pyrus calleryana underscores the high molecular diversity of the species

“…chloroplast genomes. Furthermore, in agreement with the three centers of origin for this genus, the chloroplast genomes of Asian pears P. pyrifolia (Terakami et al 2012), P. × bretschneiderii (Cho et al 2019), P. phaeocarpa (Xiang et al 2019), and P. pashia (Bao et al 2017) were in the immediate vicinity of the P. calleryana. The Middle-Eastern/Russian species P. hopeiensis (Li et al 2018) and P. ussuriensis (Gil et al 2019) placed between the Asian cluster and the European cluster of P. communis (Gil et al 2019) and P. spinosa (Korotkova et al 2018).…”
