Abstract

Rosa persica is considered a clonal plant because it is mainly propagated by clonal growth. Due to environmental degradation and habitat devastation, R. persica has been listed as a national second-class protected plant in China. However, the absence of research on wild populations of R. persica has impeded progress in formulating efficient conservation strategies. In this study, we investigated the clonal dispersal distance of R. persica to accurately determine the genetic diversity and population structure of the wild population in Xinjiang. We suggested that 20 m was the threshold distance with which to distinguish between different genets of plants. Based on this, we collated sequencing data from a total of 70 different genets of plants from 117 test samples. Eight populations of R. persica were primarily categorized into three subgroups: BL (Bole), TC (Tacheng) and CG (Changji). Of these, the CG subgroup exhibited the most genetic diversity. This research is the first to illustrates the clonal dispersal distance of R. persica, thus providing valuable reference guidelines for understanding the reproductive characteristics of clonal plants. In addition, the genetic diversity of R. persica provides a theoretical foundation for the formulation of conservation policies.

中国克隆植物蔷薇的遗传多样性评估
蔷薇被认为是一种克隆植物,因为它主要通过克隆生长繁殖。由于环境退化和栖息地破坏,蔷薇已被列为中国国家二级保护植物。然而,由于缺乏对柿树野生种群的研究,阻碍了制定有效保护策略的进展。在本研究中,我们调查了柿树的克隆扩散距离,以准确确定新疆野生种群的遗传多样性和种群结构。我们认为 20 米是区分植物不同基因组的临界距离。在此基础上,我们整理了 117 个测试样本中 70 个不同基因组植物的测序数据。柿树的八个种群主要分为三个亚群:BL(博乐)、TC(塔城)和 CG(昌吉)。其中,CG 亚群的遗传多样性最高。该研究首次说明了柿树的克隆扩散距离,从而为了解克隆植株的繁殖特性提供了有价值的参考指南。此外,柿树的遗传多样性还为制定保护政策提供了理论依据。
