Genetic and adaptive variation in beech (Fagus sylvatica): Which factors influence their spatial distribution patterns?
1. Identification of probably adaptive genes
2. Analysis of the genetic diversity within these candidate genes for the adaptive relevant traits drought resistance and bud burst, since the exploratories represent a precipitation and a temperature gradient
3. Investigation of the adaptability of beech seedlings in reciprocal translocation experiments with the aim to associate genetic variation with phenotypic traits (in a possible follow up project)
H1. We expect a higher differentiation in adaptive genes in comparison to “neutral” genetic variation.
H2. We expect the local seedling to be best adapted in comparison to seedlings from other exploratories.
H3. Furthermore, the influence of different forest management intensities on probably adaptive variation in candidate genes will be investigated.
1. Transcriptome analysis by means of next generation sequencing as well as the utilization of candidate genes already used in former studies on beech and oak (Quercus spp.)
2. Analysis of selected SNPs (Single Nucleotide Polymorphisms) within the candidate genes
3. Observation of phenotypic traits, for example survival, bud burst and growth
