Abstract

Recent sequencing technology helps analyze genome-level aberrance between wild species and highly domesticated cultivars by producing high-quality genomes. Herein, we established the complete chloroplast genome of Prunus dielsiana to lay a foundation in the future genetic comparison and modification. The chloroplast genome was 158,005 bp in length, with a large single-copy (LSC) region of 86,012 bp and a small single-copy (SSC) region of 19,121 bp, separated by two inverted repeat (IRs) regions of 26,436 bp. A total of 124 CDSs , 37 tRNA genes, and 8 rRNA genes were found. The overall GC content was 36.70%, and GC percentages ranged from 30.20 to 42.53% throughout LSC, IRs, and SSC regions. Phylogenetic analysis showed that P. dielsiana displayed a kinship to Prunus campanulata with the subsection Cerasus nested inside Prunus. This announcement of the P. dielsiana chloroplast genome sequence may provide insight into the interspecific natural hybridization in subg. Cerasus.
