Olive trees (Olea europaea) provide a good model to study the origin of cultivars due to their long lifespan. Diez et al. use SSR markers to evaluate genetic identity and diversity as well as phylogenetic relationships among the oldest wild and cultivated olives of Southern Spain. The majority (90.4 %) of the a priori cultivated ancient olive genotypes do not match any current cultivar, suggesting that a significant and valuable reservoir of genetic diversity exists among these varieties.
New study in the journal BMC Biology found that Mediterranean olives have almost as high genetic diversity as olive cultivars
Mapping a new direction for the origin and distribution of olive (Olea europaea), Mousavi et al. measure genetic diversity levels and population genetic structure of a representative set of Iranian ecotypes and...
Wild olive (Olea europaea subsp. europaea var. sylvestris, aka oleaster) populations are subject to increasing fragmentation and size reduction. Beghè et al. employ microsatellite markers and apply paternity analysis to...
