(Wangenh.) K.Koch production has expanded beyond the native distribution as the genetic diversity of the species, in part, has allowed the trees to grow under broad geographic and climatic ranges. Research in other plant species has demonstrated that the phytobiome enhances their ability to survive and thrive in specific environments and, conversely, is influenced by the prevailing environment and plant genetics, among other factors. We sought to analyze the microbiota of pecan seedlings from the controlled cross 'Lakota' × 'Oaxaca' that were made in Georgia and Texas, respectively, to determine if the maternal geographical origin influences the microbiome of the resulting progeny. No significant differences in bacterial communities were observed between the seeds obtained from the two different states ( = 0.081). However, seed origin did induce significant differences in leaf fungal composition ( = 0.012). Results suggest that, in addition to some environmental, epigenetics, or host genetic components, ecological processes, such as dispersal mechanisms of the host, differentially impact the pecan microbiome, which may have ramifications for the health of trees grown in different environments. Future studies on the role of the microbiome in plant health and productivity will aid in the development of sustainable agriculture for improved food security.
（旺根）K. 科赫的产量已超出原生分布范围，因为该物种的遗传多样性在一定程度上使树木能够在广泛的地理和气候范围内生长。对其他植物物种的研究表明，植物微生物群增强了它们在特定环境中生存和繁衍的能力，反之，它也受到主要环境和植物遗传学等因素的影响。我们试图分析分别在佐治亚州和得克萨斯州进行的‘拉科塔’ב瓦哈卡’控制杂交所得山核桃幼苗的微生物群，以确定母本的地理来源是否会影响子代的微生物组。在从两个不同州获得的种子之间，未观察到细菌群落的显著差异（ = 0.081）。然而，种子来源确实在叶片真菌组成上诱导出了显著差异（ = 0.012）。结果表明，除了一些环境、表观遗传或宿主遗传成分外，生态过程，如宿主的传播机制，会以不同方式影响山核桃微生物组，这可能对在不同环境中生长的树木健康产生影响。未来关于微生物组在植物健康和生产力方面作用的研究将有助于发展可持续农业以改善粮食安全。
