ISSR Genetic Marker Matrix for 29 Antagonistic Streptomyces Strains

Twenty-nine Streptomyces strains isolated from tobacco rhizosphere soil in Luoyang, China, are characterized by their antagonistic activity against the plant pathogen Phytophthora parasitica. The dataset is a binary matrix of 29 rows and 174 columns, where each column represents a genetic locus amplified by one of 11 specific ISSR primers. This raw data supports published research on the genetic differences and similarity among these biocontrol microorganisms.

Use Cases

• Genetic similarity and cluster analysis based on 174 ISSR marker loci.
• Strain fingerprinting and identification using the binary presence/absence patterns.
• Correlating genetic profiles with antagonistic activity against Phytophthora parasitica.
• Methodological validation for ISSR marker analysis in actinomycetes.

Strengths

• Provides the complete raw binary matrix (29x174) used in a published scientific article.
• Clearly documents the 11 specific ISSR primers used (808, 809, 810, 811, 812, 835, 836, 841, 842, 880, 884).
• Released under a permissive CC-BY-4.0 license, facilitating reuse.
• Strains have a defined origin (tobacco rhizosphere, Luoyang, China) and functional trait (antagonistic activity).

Limitations

• The specific column names for the 174 ISSR loci are not provided in the available metadata.
• Dataset is relatively small in scale (29 samples), limiting broad population-level inferences.
• No explicit documentation on DNA extraction or PCR protocols is included with the matrix.
