Population genomics of African cultivated sorghum: vcf file and passeport and archaeological data

This dataset is accompanying the manuscript "Integrating ethnolinguistic and archaeobotanical data to uncover the origin and dispersal of cultivated sorghum in Africa: a genomic perspective", available on bioRxiv under the accession 2025.04.16.648676 and is under consideration for recommendation in Peer Community in Evolutionary Biology. The aim of the study was to shed light on the domestication process of sorghum (its origin and diffusion) by integrating ethnolinguistic, archaeobotanical and genomic data. The origin and spread of cultivated sorghum were considered to result from both biological and social processes, with two leading questions: firstly, how human social groups could have contributed to the dissemination of initial sorghum populations, and secondly, how linguistic barriers could have subsequently contributed to the isolation of sorghum populations from each other and to the building of its current genetic structure. We analysed genotyping-by-sequencing data of 210 african accessions of cultivated sorghum using population genetics approach and spatially-explecit modelling to analyse the population diversity and sorghum of African cultivated sirghum, and to infer its area of origin, as well as the timing of the onset of its expansion and the speed rate of its initial diffusion. The dataverse repository consist in the genotypic data (vcf format; data_sorgho_210CoreColl‧vcf), the passport data (Dataset_S1.txt), and the table with the information on the archaeological sites considered in the study (ArcheoSitesSorghum‧txt),. The custom R codes used to performed the analyses are available on the CIRAD Gitlab platform (https://gitlab.cirad.fr/agap/sorgho/africrop_sorghum).
