For each genotype, country of origin, geographical area and classification into genetic pools as defined by Díez and colleagues [35] are shown. The number of samples (seeds) eventually retained per olive genotype after trimming host plant reads and removing samples with less than 500 sequences (see the ‘Illumina data processing’ section) are also displayed, both for the prokaryotic and the eukaryotic datasets. WW: Wild West (Olea europaea L. subsp. europaea var. sylvestris), MB: Mediterranean Basin, Q1: genetic pool 1, Q2: genetic pool 2
