Mitochondrial haplotype network constructed with wild, cultivated, landrace and ethnographic sunflowers. The size of the circles corresponds to number of individuals present, and the number of polymorphic sites between individual haplotypes is indicated by tick marks. Haplotype classes for each sample are included in Table S3. Class 1 is composed of individuals sharing the same haplotype and also those that diverge by only one or two polymorphic sites. Due to uniparental inheritance of organelles, the mitochondrial classes contain the same individuals as the plastome classes. See Figure 3 for information on the domestication haplotypes (Classes 1 and 2) and those introduced to modern cultivars during 20th‐century breeding (Classes 3 and 4)
