Paleogenomics provides new ways to study the cultural history and genetic diversity of landrace fruit crops. Paleogenomics holds the potential to unlock valuable genetic insights from extinct or ancestral fruit-crop cultivars. This information enables the reconstruction of important chapters in plant domestication and can track their ways of dispersal, introgression, and potential adaptations. Case studies on grapevines, date palms, and tomatoes, presented in this review highlight the power of paleogenomics in revealing historical aspects. The examples discussed demonstrate the importance of legacy/heritage cultivars for enhancing food security and agricultural sustainability in different environmental conditions over time.
