Allelopathic Response Data for Elymus Nutans Seed Germination and Molecular Analysis

A 10.4 KB dataset from figshare, uploaded by Huiyun Yu and last updated in May 2026. It contains results from a study exploring the allelopathic effects of Ligularia sagitta extracts on Elymus nutans, including transcriptome and metabolome analyses. The data supports research into plant stress response mechanisms in alpine grassland ecosystems.

Use Cases

• Identify differentially expressed genes involved in plant stress response based on transcriptome analysis yielding 367,463 unigenes.
• Analyze enriched metabolic pathways in response to allelopathic stress based on KEGG analysis mapping 2,683 DEGs to 133 pathways.
• Investigate the phenylpropanoid biosynthesis pathway as a core stress response mechanism based on identified key genes and metabolites.
• Correlate seed germination characteristics (germination energy, germination rate) with molecular data under different extract concentrations.

Strengths

• Integrated multi-omics data combining transcriptome (367,463 unigenes) and metabolome (361 differential metabolites) analyses.
• Specific concentration ranges (0.01–0.10 mg/mL) are identified as sensitive intervals for the allelopathic response.
• Clear pathway enrichment results with 14 significantly enriched KEGG pathways from transcriptome and 29 from metabolome data.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
