Proteomic Insights into Drought Stress Impact on Three Barley Cultivars

Proteomic Insights into the Impact of Drought Stress on Barley Grain Composition and Malt Quality is a dataset from figshare, authored by Qingqing Qin and last updated in May 2026. It contains proteomic analysis results from field-based gradient water deficit experiments on three barley cultivars (Copeland, Synergy, Planet). The study identified 1,057 differentially abundant proteins and links drought stress to changes in grain protein content, kernel weight, and malt quality indicators.

Use Cases

• Identify drought-responsive proteins in barley based on the 1,057 differentially abundant proteins identified.
• Analyze the relationship between drought stress and grain composition based on reported changes in glutenin, gliadin, and β-glucan content.
• Investigate molecular pathways affected by drought based on KEGG enrichment results for zeatin biosynthesis and starch metabolism.
• Evaluate malting process optimization strategies based on the described improvements from extended steeping and germination.

Strengths

• Proteomic analysis identified 1,057 differentially abundant proteins, providing a molecular-level view.
• Experimental design includes three distinct barley cultivars (Copeland, Synergy, Planet) for comparison.
• Links agronomic traits (thousand-kernel weight) to molecular data and end-use quality (malt friability, β-glucan).

Limitations

• Dataset size is 22.0 KB, indicating a very limited scope of data.
• Row count and column-level documentation are unknown, requiring manual inspection after download.
• Data may reflect bias inherent to the specific field-based experiments and cultivars studied.
