Genome-Wide Association Study of Brown Spot Resistance in 130 Rice Cultivars

130 rice cultivars were analyzed using a genome-wide association study to identify genes conferring resistance to brown spot disease. The study, authored by Fang-Yuan Cao and last updated in May 2026, identified two quantitative trait loci and validated the function of three candidate genes, including the novel gene OsBSR820. This is the first study to use GWAS to locate and functionally characterize brown spot resistance genes in rice.

Use Cases

• Identifying candidate genes for brown spot resistance based on GWAS results and quantitative trait loci.
• Validating gene function in plant immunity based on transgenic line experiments described in the study.
• Comparing gene family involvement in stress response based on the reported roles of exo70 and Med gene families.
• Analyzing subcellular localization patterns associated with plant defense based on the reported results.

Strengths

• Includes functional validation of candidate genes using transgenic lines, as described.
• Data is derived from a genome-wide association study of 130 distinct rice cultivars.
• Identifies a novel functional gene (OsBSR820) through GWAS-based analysis.

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 (32.0 KB), indicating limited scope or summary-level data.
