Rice Spikelet Gene Expression During ABA Biosynthesis and Glume Closure

Youming Huang's dataset contains RNA sequencing results from rice lodicules, identifying differentially expressed genes (DEGs) involved in abscisic acid (ABA) synthesis and signal transduction during spikelet opening and closing. The data, last updated in May 2026, is stored in a 5.5 KB XLS file. It was generated from experiments on fertile and sterile rice varieties treated with ABA, fluridone, and methyl jasmonate to assess glume closure and hybrid seed yield.

Use Cases

• Identify candidate genes for ABA biosynthesis based on differential expression of NCED and AAO genes.
• Analyze hormone signaling pathways during spikelet closure using expression data for PYR/PYL, SnRK2, ABF, and PP2C gene families.
• Correlate exogenous hormone application (ABA, MeJA+ABA) with gene expression changes to inform hybrid breeding strategies.
• Compare gene expression profiles between fertile and sterile rice varieties to understand genetic mechanisms of glume closure.

Strengths

• Data is derived from RNA sequencing of lodicules, a specific tissue relevant to the studied phenotype.
• Experimental design includes multiple rice varieties (fertile and sterile) and hormone treatments (ABA, FL, MeJA+ABA).
• Dataset is openly licensed under CC-BY-4.0.

Limitations

• The dataset is very small (5.5 KB), indicating limited scope or a summary-level extract.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Description metadata is limited; actual data quality requires manual inspection after download.
