Study Notes
Environmental DNA (eDNA)
- eDNA is genetic material found in environmental samples (water, soil, air)
- It provides insights into the organisms present within a given ecosystem
- eDNA analysis can detect the presence of a species even when the organism itself is not present
- Common sources of eDNA include feces, skin, gametes and carcasses
Metabarcoding
- Metabarcoding uses genetic barcodes to identify species present in an environmental sample
- It combines field-based ecology with molecular techniques and computational tools
- Allows for the identification and quantification of species in a sample
- Is more cost effective than traditional monitoring methods
Genomics
- Genomics is the study of an organism's complete set of genetic instructions
- Includes genome sequencing, annotation of gene function, and understanding genome architecture
- Also involves studying patterns of gene expression (transcriptomics), protein expression (proteomics), and metabolite flux (metabolomics).
Environmental Genomics
- Environmental genomics is a field that combines environmental toxicology and genomics
- This has led to a surge in genomic research across different species
- It is used in risk assessment for environmental factors
Benefits of eDNA Analysis
- Non invasive sampling, does not require collection of the living organism
- Can be used to detect rare species, invasive species, and species considered to be extinct
- Cost effective solution
Fungi Programs
- The 1,000 Fungal Genomes (1KFG) and Mycorrhizal Genomics Initiative are important programs for understanding fungi
- They study functional features and genetic patterns for different groups of fungi: saprophytes, symbionts, and pathogens
- Fungi play a crucial role in controlling the carbon cycle in terrestrial and aquatic ecosystems
Arthropods Program Details
- The i5k program aims to sequence 5,000 arthropod genomes in 5 years, focusing on species of agricultural, food, or medical significance
- The program contributes to the fight against pests and pathogens, advances forensic applications, improves aquaculture, and aids biodiversity conservation
Vertebrates Project Overview
- The Genome 10k project proposes a collection of genomic banks of tissues and DNA of 10,000 species of vertebrates
- The aim is to gather one specimen of each known genus
Earth Microbiome Project
- Over 200,000 samples have been analyzed using metagenomics, metatranscriptomics, and metabarcode sequencing techniques
- The goal of the project is to create a global atlas of genes and proteins from diverse ecosystems
Terragenome: Exploring Soil Microbiomes
- The Terragenome project aims to fully sequence metagenomes of various soils worldwide
- Uses metagenomics to study hundreds of thousands of soil microorganism species
- Involves experts in various fields including microbiology, ecology, molecular biology, bioinformatics, and soil physico-chemistry
Marine Genomics: Oceanomics Project
- Oceanomics studies oceanic plankton, Earth's largest planetary ecosystem
- Combines NGS sequencing with fast-rate imaging for taxonomic information extraction
- Compares biological data with environmental metadata to understand marine diversity
Marine Biotechnologies: Seaweed Project
- Explores the diverse genomics of marine macroalgae for industrial applications
- Develops new genetic tools to identify populations with industrially interesting properties
- Creates genetic maps to understand adaptation mechanisms and phenotype-environment interactions
Genomic Observatories: A Global Network
- Genomic Observatories produce long-term, contextualized biodiversity observations at the genomic level
- Represent marine and continental ecosystems worldwide
- Apply cutting-edge genomics to monitor genetic variations in human and natural ecosystems
- Aims to quantify biotic interactions and predict ecosystem services
