Unlocking Life’s Code: The San Diego Zoo Alliance and Illumina Pioneer DNA Sequencing for Frozen Zoo Samples
The San Diego Zoo Wildlife Alliance and Illumina have joined forces to apply advanced DNA sequencing to samples stored in the Frozen Zoo. This partnership will extract detailed genetic information. Consequently, it can inform conservation strategies and aid in recovering threatened species.
Frozen Zoo Overview
The Frozen Zoo is a biobank that stores viable cells, gametes, and embryos from many species. Moreover, it preserves genetic material for research, breeding programs, and possible future reintroductions.
- Samples include sperm, eggs, embryos, and cell lines.
- They are stored in cryogenic facilities to maintain viability.
- The collection supports scientific studies on genetics, disease resistance, and population health.
Illumina’s Contribution
Illumina supplies its high-throughput sequencing platforms. These technologies read DNA quickly and accurately. As a result, they turn frozen biological material into complete genomic sequences.
- DNA is extracted, fragmented, and tagged with adapters.
- The fragments are sequenced on Illumina instruments.
- Raw data is assembled and analyzed by bioinformatics teams.
Benefits of Sequencing
Genetic Diversity
Sequencing reveals variation within and between populations. Consequently, managers can avoid inbreeding. Moreover, it helps maintain healthy genetic diversity.
Disease Resistance
Genomic data can identify genes linked to pathogen resistance or susceptibility. Accordingly, conservationists can select individuals best suited for release. This ensures better adaptation to specific disease pressures.
Reintroduction & Reproductive Technologies
Detailed genetic profiles support assisted reproductive techniques, including artificial insemination and in‑vitro fertilization. Additionally, they inform which individuals are likely to thrive upon reintroduction into the wild.
Process Overview
- Sample Retrieval: A small portion of a frozen cell or gamete is removed in a sterile environment.
- DNA Extraction: The DNA is isolated from the cells.
- Library Preparation: DNA fragments are tagged with adapters.
- Sequencing: Illumina machines read the DNA bases.
- Data Analysis: Bioinformatic pipelines assemble the genome and identify variants.
- Application: The insights are used to guide breeding, disease management, and reintroduction programs.
Challenges
- Managing the large volume of genomic data requires robust storage and computing resources.
- Sequencing and analysis remain expensive, necessitating sustained funding.
- Ethical considerations arise around the use of genetic data and potential interventions.
- Data security and access policies must balance open science with protection of sensitive information.
Future Outlook
By integrating genomic data into conservation planning, the partnership sets a precedent worldwide. Consequently, continued collaboration among biobanks, technology providers, and conservation practitioners will strengthen global biodiversity preservation.
