Large‐scale genomic SNP dataset for central and southeast European Turkey oak (Quercus cerris L.) populations generated by ddRAD‐seq method

In Central and Southeast Europe, oak-dominated forests constitute the backbone of temperate forest ecosystems. Therefore, their adaptability is crucial for maintaining these ecosystems’ biodiversity under the current climate change. In this study, we investigated Turkey oak (Quercus cerris L.) populations in the Carpathian Basin and the Balkan Peninsula, as it is one of the most abundant species in these regions. The goal of our study was to build a genomic SNP dataset to enable detailed analyses of the species' biogeography, genetic diversity, population structure, and local selection and adaptation. To this end, 32 natural populations were sampled in the study regions covering most of the natural habitat range of the species. To obtain large amounts and highly variable genomic information for the sampled populations we applied double digest restriction site-associated DNA sequencing for the genotyping of the 321 sampled individuals. SNP calling was performed by using reference mapping..., , , # Large-scale genomic SNP dataset for Central and Southeast European Turkey oak (*Quercus cerris* L.) populations generated by ddRAD-seq method

## Description of the data and file structure

Our study aimed to build a genomic SNP (single nucleotide polymorphism) dataset to enable detailed analyses of the biogeography, genetic diversity, population structure, and local selection and adaptation of the Turkey oak (*Quercus cerris* L.) in the Central and Southeast European regions. To this end, 32 natural populations were sampled in the study regions covering most of the natural habitat range of the species. To obtain large amounts and highly variable genomic information for the sampled populations, we applied double digest restriction site-associated DNA sequencing (ddRAD-seq) for the genotyping of the 321 sampled individuals. As a result of SNP calling, two reference-mapped datasets were generated using t...,
