希望梨是蔷薇科梨属的珍贵野生资源。由于其分布有限，种群数量下降，已被列为中国“小种群野生植物”之一。到目前为止，对hopep .的研究还很少。本文对冀南芥资源进行了系统的综述，为冀南芥资源的保护和恢复提供依据。本研究对两种不同基因型的hopeiensis、P. ussuriensis Maxin的叶绿体基因组进行了分析。简历。金柏丽，P. communis L. cv。对早红花和白玉兰进行了测序、比较和分析。两种基因型均为典型的四分体叶绿体基因组，包括一对编码方向相同但方向相反的反向重复序列、一个大单拷贝区和一个小单拷贝区。hopeiensis HB-1叶绿体基因组长度为159,935 bp，比hopeiensis HB-2的叶绿体基因组长46 bp。两种梨基因型的SSC区和IR区长度相同，只有LSC区存在差异。而冀南草HB-1的GC含量仅高出0.02%。在叶绿体基因组的结构和大小、基因种类、基因数量、GC含量等方面与其他3种梨属植物相似。两种基因型的红外边界扩展程度相似。为了确定梨属和蔷薇科的hopeiensis的进化史，对36个蔷薇科种的57个共同蛋白编码基因进行了分析。系统进化树显示，梨属与苹果属亲缘关系较近，其中hopeiensis HB-1与hp -2亲缘关系最密切。
Pyrus hopeiensis is a valuable wild resource of Pyrus in the Rosaceae. Due to its limited distribution and population decline, it has been listed as one of the “wild plants with a tiny population” in China. To date, few studies have been conducted on P. hopeiensis. This paper offers a systematic review of P. hopeiensis, providing a basis for the conservation and restoration of P. hopeiensis resources. In this study, the chloroplast genomes of two different genotypes of P. hopeiensis, P. ussuriensis Maxin. cv. Jingbaili, P. communis L. cv. Early Red Comice, and P. betulifolia were sequenced, compared and analyzed. The two P. hopeiensis genotypes showed a typical tetrad chloroplast genome, including a pair of inverted repeats encoding the same but opposite direction sequences, a large single copy (LSC) region, and a small single copy (SSC) region. The length of the chloroplast genome of P. hopeiensis HB-1 was 159,935 bp, 46 bp longer than that of the chloroplast genome of P. hopeiensis HB-2. The lengths of the SSC and IR regions of the two Pyrus genotypes were identical, with the only difference present in the LSC region. The GC content was only 0.02% higher in P. hopeiensis HB-1. The structure and size of the chloroplast genome, the gene species, gene number, and GC content of P. hopeiensis were similar to those of the other three Pyrus species. The IR boundary of the two genotypes of P. hopeiensis showed a similar degree of expansion. To determine the evolutionary history of P. hopeiensis within the genus Pyrus and the Rosaceae, 57 common protein-coding genes from 36 Rosaceae species were analyzed. The phylogenetic tree showed a close relationship between the genera Pyrus and Malus, and the relationship between P. hopeiensis HB-1 and P. hopeiensis HB-2 was the closest.
