Summary
Google says researchers working with Australia’s CSIRO have produced two reference genomes for giant kelp and used a version of DeepVariant to analyse DNA from 600 wild specimens. The work is intended to support conservation and future breeding of heat-tolerant kelp.
Google says researchers working with Australia’s national science agency, CSIRO, have produced two reference genomes for Australian giant kelp and used a version of Google’s open-source DeepVariant tool to analyse DNA from 600 wild specimens. The samples came from 40 sites along Tasmania’s coast, where giant kelp populations have fallen to 5% of their historic numbers, according to the company.
The project combines genomic analysis with laboratory cross-breeding studies. Its longer-term aim is to help restore kelp forests using genetically diverse specimens that can tolerate heat. Google describes the work as groundwork for that outcome, rather than reporting a completed replanting effort.
Genomes provide a basis for conservation work
A reference genome is a representative DNA sequence that researchers can use as a coordinate system when studying genetic differences among individuals. Having reference genomes for giant kelp can help researchers identify and compare genetic variation in wild populations—information that may inform conservation and breeding decisions.
DeepVariant is an open-source tool for identifying genetic variants from sequencing data. Google says the researchers trained a version of it to analyse giant kelp DNA. The company’s account describes analysis of 600 specimens across 40 sites, but does not detail the variants identified or how the model was evaluated for this application.
From genetic analysis to restoration
The genetic work is being paired with laboratory cross-breeding studies. In principle, identifying variation across wild populations can help researchers select candidates for breeding; tests in the lab can then assess traits of interest, including heat tolerance. The announcement presents heat-tolerant, genetically diverse kelp as a future restoration goal, not as a result already demonstrated in restored forests.
Giant kelp forests provide habitat for marine life and help protect coastlines. Google links their worldwide decline to ocean warming. The project’s significance lies in building tools and genetic resources that may help conservationists respond to that pressure, while the practical restoration outcome depends on subsequent breeding and field work.
Google says the partnership is part of its Digital Futures Initiative in Australia.
