Abstract

The purpose of this paper is to elucidate the roles that microbes may be playing in the rootzone of the medicinal plant . We hypothesized that the microbes associated with the rootzone would be significantly different than the similar surrounding fields in composition and function. We also hypothesized that rhizospheric and endophytic microbes would be associated with similar metabolic functions to the plant rootzone they inhabited. The methods employed were microbial barcoding, tests of essential oils against antibiotic resistant bacteria and other soil bacterial isolates, 16S Next Generation Sequencing (NGS) metabarcoding, and Whole Genome Shotgun (WGS) taxonomic and functional analyses. A few of the main bacterial genera of interest that were differentially abundant in the root microbiome were ( = 0.007), ( = 0.0007), ( = 6 × 10), ( = 1 × 10), and ( = 1.46 × 10). There was significant evidence that the microbes associated with the rootzone had elevated function related to bacterial chalcone synthase ( = 1.49 × 10) and permease genes ( < 0.003). There was some evidence that microbial functions in the rootzone provided precursors to important plant bioactive molecules or were beneficial to plant growth. This is important because these compounds are phyto-protective antioxidants and are precursors to many aromatic bioactive compounds that are relevant to human health. In the context of known interactions, and current results, plants and microbes influence the flavonoid biosynthetic pathways of one other, in terms of the regulation of the phenylpropanoid pathway. This is the first study to focus on the microbial ecology of the rootzone. There are possible biopharmaceutical and agricultural applications of the natural interplay that was discovered during this study of the rhizosphere.

摘要

本文的目的是阐明微生物在药用植物根际可能发挥的作用。我们假设与根际相关的微生物在组成和功能上与周围类似田地有显著差异。我们还假设根际和内生微生物的代谢功能与它们所栖息的植物根际相似。所采用的方法包括微生物条形码技术、精油对耐抗生素细菌和其他土壤细菌分离株的测试、16S下一代测序(NGS)元条形码技术以及全基因组鸟枪法(WGS)分类和功能分析。在根际微生物群落中差异丰富的一些主要感兴趣细菌属为(=0.007)、(=0.0007)、(=6×10)、(=1×10)和(=1.46×10)。有显著证据表明,与根际相关的微生物与细菌查尔酮合酶(=1.49×10)和通透酶基因相关的功能有所增强(<0.003)。有一些证据表明,根际中的微生物功能为重要的植物生物活性分子提供了前体,或对植物生长有益。这很重要,因为这些化合物是植物保护性抗氧化剂,也是许多与人类健康相关的芳香生物活性化合物的前体。在已知相互作用和当前结果的背景下,植物和微生物在苯丙烷途径的调控方面相互影响彼此的类黄酮生物合成途径。这是第一项关注根际微生物生态学的研究。在这项根际研究中发现的自然相互作用可能具有生物制药和农业应用。
