Daphnia stressor database

Daphnia stressor database catalogs associations between environmental stressors and gene expression in Daphnia species to enable comparative annotation and interpretation of hypothetical or uncharacterized genes, with a focus on annotating Daphnia galeata transcripts.

Key Features:

• Literature-curated dataset: Aggregates and analyzes data from over 90 published Daphnia gene expression studies.
• Comparative genomics annotation: Uses comparative genomics to annotate transcripts of Daphnia galeata.
• Stressor-based annotation: Associates specific environmental stressors with corresponding gene expression patterns.
• Hypothetical protein contextualization: Annotates and contextualizes hypothetical or uncharacterized genes that are divergent from other arthropod model species.
• Linkage to variability: Connects gene expression patterns to genetic and phenotypic variability within Daphnia populations.

Scientific Applications:

• Gene function interpretation: Supports interpretation and functional inference for previously understudied or hypothetical genes.
• Ecological stress response studies: Enables analysis of cellular and organismal responses to ecological perturbations.
• Population-level analyses: Facilitates study of genetic and phenotypic variability across Daphnia populations.
• Cross-disciplinary research: Serves research in evolutionary biology, ecology, and environmental science.

Methodology:

Curated and analyzed over 90 published Daphnia gene expression studies, applied comparative genomics to annotate Daphnia galeata transcripts, and implemented a stressor-based annotation strategy linking environmental stressors to gene expression patterns.
