Abstract
The clonal diversity of Nymphoides peltata in Japan was estimated using genome-wide SNPs. In total, 27 clones were detected by considering the genetic distances between clones. The number of clones was much smaller than the estimate of 61 from a previous study that used SSR (Short Sequence Repeats) markers. This may be because population have diminished due to environmental deterioration over the past decade, fewer samples were analyzed in this study, or there were technical problems with the SSR markers used in the previous study. The populations of N. peltata were genetically differentiated between the western and eastern regions of the Japanese archipelago. Artificial movements may have occurred in a few populations.
利用全基因组单核苷酸多态性(SNPs)估计了日本peltata Nymphoides的克隆多样性。考虑到无性系之间的遗传距离，共检测到27个无性系。克隆数量远少于先前使用SSR(短序列重复)标记的研究估计的61个。这可能是由于近十年来环境恶化导致种群数量减少，本研究分析的样本较少，或者之前研究中使用的SSR标记存在技术问题。在日本列岛的西部和东部地区，peltata N. peltata的种群存在遗传分化。在少数种群中可能发生了人为的迁徙。
期刊介绍：
Aquatic Botany offers a platform for papers relevant to a broad international readership on fundamental and applied aspects of marine and freshwater macroscopic plants in a context of ecology or environmental biology. This includes molecular, biochemical and physiological aspects of macroscopic aquatic plants as well as the classification, structure, function, dynamics and ecological interactions in plant-dominated aquatic communities and ecosystems. It is an outlet for papers dealing with research on the consequences of disturbance and stressors (e.g. environmental fluctuations and climate change, pollution, grazing and pathogens), use and management of aquatic plants (plant production and decomposition, commercial harvest, plant control) and the conservation of aquatic plant communities (breeding, transplantation and restoration). Specialized publications on certain rare taxa or papers on aquatic macroscopic plants from under-represented regions in the world can also find their place, subject to editor evaluation. Studies on fungi or microalgae will remain outside the scope of Aquatic Botany.
