![]() ![]() The Aquatic Symbiosis Genomics (ASG) project is sequencing the genomes of symbiotic systems. Or follow DToL on Twitter Aquatic Symbiosis Genomics To find out more, visit the Darwin Tree of Life website. The aim of the Darwin Tree of Life (DToL) project is to produce reference genomes for each of the estimated 70,000 eukaryotic species in Britain and Ireland.ĭToL is a partnership between biodiversity, genomics and analytics partners: Sanger, the Earlham Institute, EMBL-EBI, the Marine Biological Association, the Natural History Museum in London, the Royal Botanic Gardens at Edinburgh and Kew, and the universities of Cambridge, Edinburgh and Oxford. However, the bulk of our teams’ time is focused on a handful of these transformative initiatives. The Tree of Life Programme is a partner in many research projects (see below under ‘Collaborations’). The assembly is also annotated by our partners at EMBL-EBI, and a Genome Note is published to announce the new assembly and how we did it. ![]() Our scientists have developed several powerful automated tools to help do this accurately at scale, but some key stages of the process are still done manually by eye!įinally, the genome assemblies are submitted to the publicly accessible European Nucleotide Archive (ENA) database. These large segments of DNA are then assembled and curated by teams of bioinformaticians. Once extracted, the genetic material is then sequenced using the latest long-read technologies. ![]() This ensures samples are collected ethically and legally, and transported in such a way that the required High Molecular Weight DNA can be extracted. Tree of Life has assembled a world-leading genome production pipeline. In this way, it becomes quicker, cheaper and more efficient to study organisms’ biology and evolution, support conservation efforts, or search for new biomedicines and other compounds. For example, scientists can use resequencing to look at the DNA of other individuals within the same species and compare back to the reference genome. Once a reference genome is available, a whole toolkit of other exciting methods and techniques are unlocked. The chart below shows how this translates up the taxonomic hierarchy. There is much ground to cover, with sequence data available for only 0.8% of Earth’s species. This is a quarter to a third of their project which would be better spent probing the questions they set out to study – if only the relevant reference genome were available. Currently, a typical PhD researcher might spend up to a year sequencing the genome for their chosen species. We want the next generation of scientists to operate in a genome-ready world. This exacting standard, which we expect to stand the tests of future science, has only recently been achievable using the latest long-read and long-range sequencing technologies. Genes are then identified and features annotated to help users make sense of how different parts of the sequence function. This means complete genome sequences that span each chromosome of the nuclear genome (the DNA in the nucleus), plus the genetic material in all organelles (e.g. Tree of Life aims for the highest standard of genome assemblies wherever possible. We believe this young and growing scientific field, known as Biodiversity Genomics, will transform the way we do biology. The goal is to produce reference genomes for all 1.2 million known species on Earth. This is a network of affiliated biodiversity genomics projects from across the globe, all sharing the common aim to “sequence everything”. Tree of Life’s projects operate in tandem with a global initiative called the Earth BioGenome Project. Alongside this reference genome production, research teams within Tree of Life are exploring questions around ecosystem function, species radiations, reproductive diversity and more.Īll our data – including as much work-in-progress as possible – is published openly and available freely to researchers across the world. At the core of our research is the production of high-quality reference genomes for individual species, which our teams are producing at an unprecedented scale. ![]()
