The rhizosphere influence on the soil microbiome and function of crop wild progenitors (CWPs) remains virtually unknown, despite its relevance to develop microbiome‐oriented tools in sustainable agriculture. Here, we quantified the rhizosphere influence—a comparison between rhizosphere and bulk soil samples—on bacterial, fungal, protists and invertebrate communities and on soil multifunctionality across nine CWPs at their sites of origin. Overall, rhizosphere influence was higher for abundant taxa across the four microbial groups and had a positive influence on rhizosphere soil organic C and nutrient contents compared to bulk soils. The rhizosphere influence on abundant soil microbiomes was more important for soil multifunctionality than rare taxa and environmental conditions. Our results are a starting point towards the use of CWPs for rhizosphere engineering in modern crops.

土壤微生物组的丰富部分调节作物野生祖先的根际功能


尽管根际与开发可持续农业中以微生物组为导向的工具相关，但根际对土壤微生物组和作物野生祖细胞（CWP）功能的影响实际上仍然未知。在这里，我们量化了根际影响（根际和土壤样本之间的比较）对细菌、真菌、原生生物和无脊椎动物群落以及九个 CWP 起源地土壤多功能性的影响。总体而言，与大块土壤相比，四个微生物类群的丰富类群的根际影响较高，并对根际土壤有机碳和养分含量产生积极影响。根际对丰富土壤微生物组的影响对于土壤多功能性比稀有类群和环境条件更重要。我们的结果是在现代作物中使用 CWP 进行根际工程的起点。
