Olive /橄榄
Taxonomy: Angiosperms / Eudicots / Asterids / Lamiales / Oleaceae / Olea
Introduction
1. The olive tree, Olea europaea, has been cultivated for olive oil, fine wood, olive leaf, ornamental reasons, and the olive fruit. About 90% of all harvested olives are turned into oil, while about 10% are used as table olives.
2. Olive trees show a marked preference for calcareous soils, flourishing best on limestone slopes and crags, and coastal climate conditions.
3. Olives are one of the most extensively cultivated fruit crops in the world.
4. One hundred grams of cured green olives provide 146 calories, are a rich source of vitamin E , and contain a large amount of sodium ; other nutrients are insignificant.
5. Olive tree pollen is extremely allergenic, with an OPALS allergy scale rating of 10 out of 10.

Methods
We sampled and sequenced twelve genomes of O. europaea: ten cultivars (“Arbequina”, “Beladi”, “Picual,” “Sorani,” “Chemlal de Kabilye,” “Megaritiki,” “Lechin de Sevilla,” “Lechin de Granada,” “Frantoio,” and “Koroneiki”), one oleaster (sylvestris-S), and one subsp. cuspidata to be used as an outgroup. The inclusion of outgroups in phylogenomic analyses is recommended as they help to provide a temporal polarity to the data (e.g., distinguish between ancestral and derived characters). These samples broadly covered the geographical distribution of the species in the MB (see Table 1). The authenticity of these cultivars was previously substantiated through molecular and morphological markers [9]. The sequenced oleaster (referred to as sylvestris-S from now onwards) was collected in the North of Spain. All the samples were collected according to the local, national, or international guidelines and legislation.
