PEO

PEO provides a curated compendium of plant gene expression data to enable identification of organ-specific genes and co-expression relationships across plant species.

Key Features:

• Species coverage: Contains expression data spanning over 100 plant species.
• RNA-seq sample collection: Aggregates approximately 60,000 manually annotated RNA-seq samples.
• Gene catalog: Hosts expression data for more than 4 million genes.
• Organ-specific expression profiling: Enables exploration of gene expression patterns across various organs and identification of organ-specific genes.
• Co-expression analysis: Provides identification of top co-expressed genes for any gene of interest.
• Functional annotation: Supplies functional annotations for each gene to support identification of genetic modules and pathways.
• Comparative kingdom-wide analysis: Supports comparative gene expression analyses across the plant kingdom.

Scientific Applications:

• Pollen coat biosynthesis (Arabidopsis): Used to identify candidate genes involved in pollen coat biosynthesis in Arabidopsis.
• Capsaicin biosynthetic pathway (Capsicum annuum): Used to investigate components of the capsaicin biosynthetic pathway in Capsicum annuum.
• Comparative expression studies: Enables cross-species comparative analyses to uncover gene function and expression conservation across plants.

Methodology:

Aggregates approximately 60,000 manually annotated RNA-seq samples and expression data for more than 4 million genes and provides gene-level functional annotations used for organ-specific and co-expression analyses across plant species.
