Native plant materials (NPMs) are increasingly utilized during the restoration of disturbed plant communities. Here, we analyze next‐generation genetic sequencing data for Hilaria jamesii, a dominant graminoid across drylands of the southwestern United States, and document that the species' only commercially‐available NPM, “Viva,” is a hybrid between H. jamesii and its sister species, Hilaria mutica. In fact, hybrids between these species are common where they geographically overlap. Furthermore, we show that the “Viva” hybrid has successfully been moved beyond the hybrid zone and into the core range of H. jamesii. The potential ramifications of introducing novel genetic material into H. jamesii are discussed, as well as the utility of genetic analyses to protect species' natural patterns of genetic diversity and help managers make informed decisions regarding the development and deployment of NPMs.

意外的杂交揭示了遗传学在天然植物修复中的作用

恢复受干扰的植物群落期间,越来越多地利用本地植物材料(NPM)。在这里,我们分析了Hilaria jamesii的下一代基因测序数据,Hilaria jamesii是美国西南部干旱地区的主要类蠕虫,并记录了该物种唯一的商业可用NPM“ Viva”是jamesii与其杂交种之间的杂种姐妹种,Hilaria mutica。实际上,这些物种之间的杂种在地理上重叠的地方很常见。此外,我们表明“ Viva”杂种已成功地移出杂种区并进入了詹姆逊氏酵母的核心范围。将新的遗传物质引入詹姆斯氏嗜血杆菌的潜在后果 讨论了遗传分析的用途,以及遗传分析在保护物种自然遗传多样性和帮助管理人员做出有关NPM开发和部署的明智决策方面的作用。
