Project status Pilot year project completed
Project funding £162,000
Research outcome Adaptation
Context
This pilot project will germinate and generate genome-wide Single Nucleotide Polymorphism (SNP) data for around 1,500 seedlings from 2–3 species of tree that have been banked under the UK National Tree Seed Project (UKNTSP) that have short germination times, such as downy and silver birch.
The population structure of each of the target species’ UK distribution will be analysed and interpreted with reference to the history of colonisation and planting in the UK. We will carry out genome-environment association (GEA) studies to seek genes involved in local adaptation.
Expected outcomes
- UK-wide, publicly available genome-wide SNP data for 2–3 UK broadleaved tree species.
- A report and assessment of the degree of local adaptation in UK populations of these species and suggestions as to how these data could inform seed sourcing for tree planting projects.
Silver birch (Betula pendula) seedling.
Glossary
Genome-environment association (GEA)
The statistical relationship between genetic variations (genotypes) and environmental factors. It is a method used to study how organisms adapt to their local environments by identifying specific genes that are associated with particular environmental conditions.
Single nucleotide polymorphism (SNP)
A variation at a single position in a DNA sequence among individuals.
