Methods

Whole-genome sequencing

In this project, the entire genome of all sampled trees is sequenced (at least 2200 individuals in total). This approach offers the following advantages over other genetic methods:

  • Capture of the entire genomic information of an individual
  • Precise picture of the genetic diversity existing today
  • In-depth conclusions about historical processes (e.g. demography, gene flow)
  • Characterization of genetic diversity relevant to adaptation (e.g. in relation to climate, soil, etc.)
  • Unbiased comparison between species
  • Unbiased comparison with future genetic surveys (time series, monitoring)

 

Requirements & effects

  • Reference genome
  • Costs dependent on genome size
  • Large amounts of data, large storage space
  • Large time and computational effort for the analyses
