High genetic diversity detected in olives beyond the boundaries of the Mediterranean Sea.

<h4>Background</h4>Olive trees (Olea europaea subsp. europaea var. europaea) naturally grow in areas spanning the Mediterranean basin and towards the East, including the Middle East. In the Iranian plateau, the presence of olives has been documented since very ancient times, though the e...
