Opaque-2 Mutation Effects on Sweet Corn Protein and Amino Acid Profiles

A 214.1 KB PDF file contains data from a study introducing the opaque-2 mutation into sweet corn to improve protein quality. The dataset likely contains biochemical assay results for lysine, other amino acids, sugar, and starch content across six inbred and twelve hybrid quality protein sweet corn lines. The data was authored by Jonathan Niyorukundo and uploaded to figshare under a CC-BY-4.0 license, with a last update timestamp of 2026-05-14.

Use Cases

• Analyzing the relationship between zein protein reduction and lysine increase based on the opaque-2 mutation.
• Comparing amino acid profiles between quality protein sweet corn hybrids and their wild-type parents.
• Evaluating the impact of the opaque-2 mutation on secondary quality traits like sugar and starch content.
• Selecting breeding lines for tender texture and satisfactory sweetness alongside improved protein quality.

Strengths

• The study provides proof of concept for improving sweet corn protein quality without penalties on other traits.
• The dataset includes results from six inbred and twelve hybrid corn lines, suggesting a comparative analysis is possible.
• Data is shared under a permissive CC-BY-4.0 license, allowing for reuse.

Limitations

• The dataset is small at 214.1 KB, indicating limited scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
