abalonedb

abalonedb provides genomic and transcriptomic resources for Haliotis laevigata, including a draft genome, transcriptomes from 11 tissues, analyses of neuropeptides (including an egg‑laying hormone that enabled spawning induction at 80% efficiency), and phylogenetic data indicating ~71 million years divergence from Haliotis discus hannai to support genetic, evolutionary, and aquaculture research.

Key Features:

• Draft genome: Provides access to a draft genome assembly of Haliotis laevigata.
• Transcriptomic datasets: Includes transcriptome data derived from 11 different tissues of an adult female greenlip abalone.
• Reproductive biology analyses: Identifies neuropeptides involved in gonad maturation and spawning, including isolation of an egg‑laying hormone with demonstrated spawning induction (~80% efficiency).
• Phylogenetic data: Contains analyses supporting evolutionary timelines, including an estimated divergence of ~71 million years from Haliotis discus hannai.
• Applications for breeding and health: Enables studies aimed at genetic diversity assessment, breeding program development, disease resistance, and environmental adaptation strategies.

Scientific Applications:

• Evolutionary studies: Use phylogenetic data to investigate relationships within Haliotidae and estimate divergence times.
• Genomic research: Identify genes associated with growth, disease resistance, and other traits relevant to Haliotis laevigata.
• Aquaculture enhancement: Inform breeding programs and reproductive management through genomic, transcriptomic, and neuropeptide data.

Methodology:

Sequencing of the Haliotis laevigata genome, generation of transcriptomic data from multiple tissues, phylogenetic analyses to assess evolutionary timelines, and biochemical studies to identify neuropeptides and an egg‑laying hormone were performed.
