Sponge Larvae Molecular Responses to Condensate Oil Exposure

Six treatment dilutions of a water accommodated fraction of partially weathered condensate oil were applied to Phyllospongia foliascens sponge larvae for 24 hours. The collection includes larval settlement data, differential gene expression from Tag-based RNA-Seq, and microbial amplicon sequence variant data from 16S rRNA sequencing. Data is associated with research by Luter et al. (2024) and raw sequencing files are available in the NCBI Sequence Read Archive under BioProject PRJNA1012550.

Use Cases

• Modeling dose-response relationships for larval settlement based on six oil treatment dilutions.
• Analyzing differential gene expression patterns in response to hydrocarbon exposure.
• Profiling shifts in associated microbial communities (ASV data) under toxic stress.
• Integrating multi-omic data (transcriptomic and microbial) for a holistic toxicity assessment.

Strengths

• Data is linked to a full research publication (Luter et al., 2024) with supplementary materials and a GitHub repository for methodological details.
• Chemical characterization of the oil exposure medium is provided in a referenced prior study (Negri et al., 2021).
• Raw sequencing data is publicly archived in the NCBI SRA under a specific BioProject number (PRJNA1012550).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and species bias inherent to the single-species experiment on an Indo-Pacific sponge.
