Abstract

The peach (Prunus persica L. Batsch) is one of the important stone fruit crops in the Crimea Peninsula and the southern part of Russia. The complete chloroplast genome of the peach cultivar ‘Sovetskiy’ is published in this paper. The chloroplast genome size is 157,756 bp. It contains 126 genes, including 81 protein-coding genes (PCGs), eight ribosomal RNA (rRNA) genes, and 37 transfer RNA (tRNA) genes. The chloroplast genome also contains a large single-copy region of 85,960 bp, a small single-copy (SSC) region of 19,045 bp, and two inverted repeats regions of 26,375 bp and 26,372 bp. The overall base composition of the genome in descending order is 31.2% – A, 32.1% – T, 18.7% – C, and 18.0% – G. The total GC content of the chloroplast genome is 36.7%. Maximum-likelihood phylogenetic analysis involving nine chloroplast genomes of the Prunus genus revealed a separate cluster for P. persica and its possible landrace – P. ferganensis.

摘要

桃 ( Prunus persicaL. Batsch）是克里米亚半岛和俄罗斯南部的重要核果作物之一。本文发表了桃品种“Sovetskiy”的完整叶绿体基因组。叶绿体基因组大小为 157,756 bp。它包含126个基因，包括81个蛋白质编码基因（PCG）、8个核糖体RNA（rRNA）基因和37个转移RNA（tRNA）基因。叶绿体基因组还包含一个 85,960 bp 的大单拷贝区域、一个 19,045 bp 的小单拷贝 (SSC) 区域和两个 26,375 bp 和 26,372 bp 的反向重复区域。基因组整体碱基组成按降序排列为31.2%-A、32.1%-T、18.7%-C和18.0%-G。叶绿体基因组总GC含量为36.7%。涉及李属九个叶绿体基因组的最大似然系统发育分析该属揭示了P. persica及其可能的地方品种P. ferganensis的单独集群。
