Abstract

Prunus glandulosa Thunb. is an ornamental species in the genus Prunus (Rosaceae) mainly distributed in eastern China. It is often cultivated in gardens, roadsides, or shrub clusters. It looks like a cherry but resembles to prunes as well. We obtained the complete chloroplast genome of P. glandulosa using next-generation sequencing technology. The chloroplast genome is 158.078 bp in length with typical tetrad structure. It includes two copies of inverted repeats (IRs, 26.385 bp), a large single copy (LSC, 86.269 bp) and a small single copy (SSC, 19.039 bp). The total GC content is 36.7%, including 85 protein-coding genes (PCGs), 36 transfer RNA genes (tRNA), and eight ribosomal RNA genes (rRNA). The maximum-likelihood phylogeny using the full length of chloroplast genomes indicates that P. glandulosa is closer to prunes than to cherries.

Highlights

  • Prunus glandulosa Thunb. is an ornamental species in the genus Prunus (Rosaceae) mainly distributed in eastern China

  • Total genomic DNA was extracted from the silica gel dried and clean leaves of P. glandulosa sampled from Wuhan Botanical Garden (China; N3031021.6200, E11425034.9900)

  • An Illumina DNA library was constructed using the total DNA and the DNA library was sequenced on Illumina HiSeq2500 platform for paired-end 150 bp reads (PE150)
