Abstract

'Yunhongli No. 1' is a rare and well-colored red pear (Pyrus pyrifolia) germplasm resource, and is popular in the market due to its bright red color and high quality. This study used Illumina high-throughput sequencing technologies for red pear 'Yunhongli No. 1' of chloroplast genome sequencing and analysis. The genome features of P. pyrifolia 'Yunhongli No. 1' and the phylogenetic relationships were reported and established. The complete chloroplast genome is 160,113 bp in length, consisting of a pair of inverse duplication regions 26,386 bp, a large single-copy region 88,052 bp, and a small single-copy region 19,214 bp. The entire genome contains 80 messenger RNA (mRNA) genes, 30 transfer RNA (tRNA) genes, and 4 ribosomal RNA (rRNA) genes. The phylogenetic tree of 15 Rosaceae species revealed red pear 'Yunhongli No. 1' is more closely related to Pyrus communis × P. pyrifolia 'Greensis.'

Keywords: Pyrus pyrifolia; Red pear ‘Yunhongli No. 1’; chloroplast genome; phylogenetic analysis.
