Plant-beneficial microbial inoculants are often outcompeted by native soil microbes in the field. A new study shows that fierce competition among the most beneficial microbes leads to a reduction in their abundance in the soil, which, in turn, reduces plant growth.

Plant Species Richness and the Root Economics Space Drive Soil Fungal Communities.

Trait-based approaches have been increasingly used to relate plants to soil microbial communities. Using the recently described root economics space as an approach to explain the structure of soil-borne fungal communities, our study in a grassland diversity experiment reveals distinct root trait strategies at the plant community level. In addition to significant effects of plant species richness, we show that the collaboration and conservation gradient are strong drivers of the composition of the different guilds of soil fungi.

Introduction: Functional rhizosphere microbiomes (FRM) are critical for plant health and yield. However, the ecological succession of FRM and their links to plant genetic factors across the life cycle of perennial plants remain poorly understood.
Methods: This study profiled FRM, including plant-beneficial bacteria (PBB) and fungal plant pathogens (FPP), across different developmental stages of .

Saline-alkali soil severely reduces the productivity of crops, including maize (Zea mays). Although several genes associated with saline-alkali tolerance have been identified in maize, the underlying regulatory mechanism remains elusive. Here, we report a direct link between colonization by arbuscular mycorrhizal fungi (AMF) and saline-alkali tolerance in maize.

Rhizosphere microorganisms are important factors affecting herb quality and secondary metabolite accumulation. In this study, we investigated the diversity of rhizosphere microbial communities (bacteria and fungi) and their correlations with soil physicochemical properties and active compounds of (baicalin, oroxindin, baicalein, wogonin, and oroxylin A) from cultivated with three different origins high-throughput sequencing and correlation analysis to further clarify the role of soil factors in the accumulation of the active compounds of . The results are summarized as follows.

Saline-alkali land is a type of soil environment that causes poor crop growth and low yields. Its management and utilization are, therefore of great significance for increasing arable land resources, ensuring food security, and enhancing agricultural production capacity. The application of plant growth-promoting rhizobacteria (PGPR) is an effective way to promote the establishment of symbiotic relationships between plants and the rhizosphere microenvironment, plant growth and development, and plant resistance to saline-alkali stress.
