To explore and utilize the abundant soil microorganisms and their beneficial functions, high-throughput sequencing technology was used to analyze soil microbial compositions in the rhizosphere of red and green amaranth varieties. The results showed that significant differences in soil microbial composition could be found in the rhizosphere of amaranth plants with different color phenotypes. Firstly, soil bacterial compositions in the rhizosphere were significantly different between red and green amaranths. Among them, , , , , and were the unique dominant soil bacterial genera in the rhizosphere of red amaranth. In contrast, , , and were the special dominant soil bacterial genera in the rhizosphere of green amaranth. Additionally, even though the soil fungal compositions in the rhizosphere were not significantly different between red and green amaranths, the abundance of the dominant soil fungal genera in the rhizosphere showed significant differences between red and green amaranths. For example, , , , and significantly enriched as the dominant soil fungal genera in the rhizosphere of the red amaranth. In contrast, only significantly enriched as the dominant soil fungal genus in the rhizosphere of green amaranth. All of the above results indicated that amaranth with various color phenotypes exactly recruited different microorganisms in rhizosphere, and the enrichments of soil microorganisms in the rhizosphere could be speculated in contributing to amaranth color formations.
为了探索和利用丰富的土壤微生物及其有益功能，采用高通量测序技术分析了红色和绿色苋菜品种根际土壤微生物组成。结果表明，不同颜色表型的苋菜植株根际土壤微生物组成存在显著差异。首先，红色和绿色苋菜根际土壤细菌组成存在显著差异。其中，[具体细菌属1]、[具体细菌属2]、[具体细菌属3]、[具体细菌属4]、[具体细菌属5]和[具体细菌属6]是红色苋菜根际独特的优势土壤细菌属。相比之下，[具体细菌属7]、[具体细菌属8]和[具体细菌属9]是绿色苋菜根际特殊的优势土壤细菌属。此外，尽管红色和绿色苋菜根际土壤真菌组成没有显著差异，但根际优势土壤真菌属的丰度在红色和绿色苋菜之间存在显著差异。例如，[具体真菌属1]、[具体真菌属2]、[具体真菌属3]、[具体真菌属4]和[具体真菌属5]在红色苋菜根际显著富集为优势土壤真菌属。相比之下，[具体真菌属6]仅在绿色苋菜根际显著富集为优势土壤真菌属。上述所有结果表明，不同颜色表型的苋菜在根际确实招募了不同的微生物，并且可以推测根际土壤微生物的富集有助于苋菜颜色的形成。
