Biocontrol Effects of Two Paenibacillus Strains on Astragalus Root Rot and Soil Microbes

Two Paenibacillus strains, HQ-1 and HQT-2, demonstrated over 80% preventive efficacy against Astragalus membranaceus root rot in greenhouse trials. The dataset, authored by Chenying Wu and last updated in 2026, likely contains results from in vitro assays, colonization studies, and metagenomic analysis of treated soils. It provides systematic evidence on the efficacy of P. terrae in biocontrol, addressing a noted gap in the literature.

Use Cases

• Compare the biocontrol efficacy of different Paenibacillus species based on the reported preventive efficacy rates of 86.046% and 80.619%.
• Analyze shifts in soil microbial community structure following biocontrol treatment based on the metagenomic analysis mentioned.
• Study the plant growth-promoting traits of bacterial antagonists based on the described multiple traits of the isolated strains.
• Investigate the colonization potential of biocontrol bacteria on plant roots based on the GFP labeling verification described.

Strengths

• Reports specific, high preventive efficacies of 86.046% for strain HQ-1 and 80.619% for strain HQT-2.
• Includes multiple analytical angles: in vitro assays, greenhouse trials, and metagenomic analysis.
• Addresses a specific research gap regarding the biocontrol efficacy of Paenibacillus terrae.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small (15.3 KB), indicating limited scope.
