Eragrostis Curvula Gene Expression Data for Apomixis Candidate Genes

130 of 131 differentially hybridized probes were upregulated in apomictic plants of the perennial forage grass Eragrostis curvula. This dataset, authored by Ingrid Garbus and last updated in April 2026, contains results from a comparative gene expression analysis using a custom 1×1M Agilent microarray. It identifies four candidate genes, two of which were exclusively present in apomictic individuals, with functional assessment conducted via heterologous expression in Arabidopsis.

Use Cases

• Identify candidate genes associated with apomictic reproduction based on comparative gene expression profiles.
• Validate gene-trait associations based on PCR screening results across sexual and apomictic genotypes.
• Assess the functional impact of candidate genes based on heterologous expression phenotypes in Arabidopsis.
• Investigate conserved reproductive pathways based on the disruption observed in transgenic lines.

Strengths

• Integrative analysis combines gene expression profiling with functional assays in a heterologous system.
• PCR screening across 14 genotypes and a mapping population provides validation for candidate gene presence.
• Four specific candidate genes are identified, including EcAPO1 and EcAPO2 which were exclusive to apomictic plants.
• Data is openly available under a CC-BY-4.0 license.

Limitations

• Dataset is very small at 15.5 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.
