Water Flux and Aquaporin Dynamics in Pearl Millet Hybrids

Data Sheet 1 contains physiological, anatomical, and molecular data from a study on water-saving traits in pearl millet. The study by Susan Medina, uploaded to figshare in 2026, investigated four contrasting hybrids bred for high and low rainfall zones. It integrates transpiration responses, root pressurization, anatomical characterization, and transcriptional profiling of aquaporin genes.

Use Cases

• Modeling hydraulic strategies in crops based on transpiration responses to vapor pressure deficit (VPD).
• Analyzing the relationship between root anatomy and water transport based on metaxylem proliferation data.
• Investigating gene expression patterns for drought response based on transcriptional profiling of PIP and TIP genes.
• Comparing water-use efficiency between crop genotypes based on physiological assays of root hydraulic conductivity.

Strengths

• Data integrates multiple phenotyping levels: physiological, anatomical, and molecular.
• Study design compares four genetically distinct hybrids from contrasting breeding histories.
• File is licensed under CC-BY-4.0, permitting open sharing and adaptation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The primary data file is a DOCX document, which may require parsing to extract structured data.
