Rice idr1-1 Mutant Transcriptomes Under Osmotic Stress

Transcriptomic analyses of rice leaves from idr1–1 mutant and wild-type seedlings exposed to osmotic stress reveal thousands of differentially expressed genes. The dataset, authored by Tiange Hu and last updated in May 2026, includes results from early and middle stress stages. Gene Ontology analyses link these changes to stress responses and photosynthetic system maintenance.

Use Cases

• Identify candidate genes for osmotic stress tolerance based on differentially expressed gene lists.
• Analyze stage-specific biological processes altered by the idr1-1 mutation using Gene Ontology term associations.
• Investigate protein interaction networks involving IDR1 and its five identified partners (OsFLU1, OsHHO3, OsRLIN1, NADPH HC, OsS40-14).
• Compare transcriptional responses between early-stage (phytohormone, ROS, stomatal movement) and middle-stage (photosynthetic systems) osmotic stress.

Strengths

• Includes specific counts of differentially expressed genes: 2881 upregulated and 2191 downregulated in early stress, 2824 upregulated and 2153 downregulated in middle stress.
• Identifies overlapping gene sets co-regulated by mutation and stress: 44 genes in early stage and 325 in middle stage.
• Provides biological interpretation through Gene Ontology analyses for both stress stages.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is provided in a DOCX file format (2.7 MB), which may require extraction to access underlying tables.
