Soybean is a significant export product for several countries, including the United States and Brazil. There are numerous varieties of soybean. Among them, a genetically modified type known as INTACTA RR2 PRO™ has been designed to demonstrate resistance to glyphosate and to produce toxins that are lethal to several species of caterpillars. Limited information is available on the use of and to promote plant growth and their impact on the plant microbiome.
This study aimed to evaluate the effects of these microorganisms on this soybean cultivar by analyzing parameters, such as root and shoot dry matter, nutritional status, and root and soil microbial diversity.
The results indicated that treatments with alone or in combination with as seed or seed and soil applications significantly enhanced plant height and biomass compared to the other treatments and the control. No significant differences in phosphorus and nitrogen concentrations were detected across treatments, although some treatments showed close correlations with these nutrients. Microbial inoculations slightly influenced the soil and root microbiomes, with significant beta diversity differences between soil and root environments, but had a limited overall impact on community composition.
The combined application of and particularly enhanced plant growth and promoted plant-associated microbial groups, such as Rhizobiaceae, optimizing plant-microbe interactions. Furthermore, the treatments resulted in a slight reduction in fungal richness and diversity.
大豆是包括美国和巴西在内的几个国家的重要出口产品。大豆有许多品种。其中，一种名为INTACTA RR2 PRO™的转基因品种被设计为具有抗草甘膦能力，并能产生对几种毛虫有毒的毒素。关于[具体微生物名称1]和[具体微生物名称2]用于促进植物生长及其对植物微生物组的影响的信息有限。
本研究旨在通过分析根和茎干物质、营养状况以及根和土壤微生物多样性等参数，评估这些微生物对该大豆品种的影响。
结果表明，与其他处理和对照相比，单独使用[具体微生物名称1]或与[具体微生物名称2]组合作为种子处理或种子和土壤处理，显著提高了株高和生物量。各处理间磷和氮浓度未检测到显著差异，尽管一些处理与这些养分显示出密切相关性。微生物接种对土壤和根微生物组有轻微影响，土壤和根环境之间存在显著的β多样性差异，但对群落组成的总体影响有限。
[具体微生物名称1]和[具体微生物名称2]的联合应用尤其促进了植物生长，并促进了与植物相关的微生物类群，如根瘤菌科，优化了植物 - 微生物相互作用。此外，这些处理导致真菌丰富度和多样性略有降低。
