Rhizosphere Microbiome Shifts for Summer Legume Cover Crops in Organic Systems

Table 3_Functional and taxonomic shifts in rhizosphere microbiomes of summer legume cover crops.xlsx contains data from a study comparing rhizosphere bacterial communities associated with cowpea, tepary bean, and sunn hemp against fallow soils in an organic production system. The dataset, authored by Sri Kiran Reddy Alla and last updated in May 2026, likely includes relative abundances, taxonomic assignments, and functional predictions derived from 16S rRNA amplicon sequencing and PICRUSt2 analysis.

Use Cases

• Compare bacterial community composition between legume species and fallow soils based on described taxonomic shifts.
• Analyze species-specific recruitment patterns for nitrogen-fixing or organic matter turnover bacteria mentioned in the description.
• Investigate predicted functional pathways related to carbon metabolism and nitrogen metabolism under legume rhizospheres.
• Validate or extend findings on weighted UniFrac separation accounting for approximately 54% of community variation.

Strengths

• Data is derived from a controlled study using 16S rRNA amplicon sequencing, a standard method for microbial community profiling.
• Functional predictions were generated using PICRUSt2, suggesting representation of pathways for carbon metabolism, amino acid biosynthesis, and siderophore production.
• Weighted UniFrac analysis indicated clear separation between treatments, accounting for approximately 54% of community variation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for certain analyses.
• The description notes that predicted pathways for nitrogen metabolism did not remain significant after false discovery rate correction.
