Whole genome sequencing of Fagus sylvatica tree to investigate genetic heterogeneity between mono- and multi-specific plots in mixed forests

We compared genomes of beech trees growing either in monospecific or multispecific plots, along sites in the French Alps. We found a high genetic association at specific loci between SNP profiles and the monospecific or multispecific tree community composition. The studied mixed forests appear as genetic patchworks structured at the sub-population level.
