Olive
Olea europaea
Olea europaea, commonly known as the olive tree, is a traditional plant with its roots deeply embedded in Mediterranean and Middle Eastern cultures. Traditionally, it has been used for various purposes such as food, oil production, and even medicinal applications like treating skin conditions; however, specific traditional uses are not well-documented. Scientific evidence indicates moderate to high genetic diversity among olive accessions, particularly noted in wild populations from Oman's mountains. Genetic analyses have shown a north-south split with distinct lineages, while phenotypic studies revealed variation in fruit and leaf traits. Some research suggests that maslinic acid treatments may offer partial protection against oxidative stress following testicular injury in rats. Additionally, the use of MICOSAT F® as a microbial biostimulant has been associated with enhanced growth and altered metabolic processes in olive trees, potentially improving their climate resilience. Safety concerns are minimal, with no major issues recorded, and there is currently no evidence of significant drug interactions.

What the science says
- Genetic and phenotypic analyses of 'Mehras' olive accessions revealed moderate to high genetic diversity with clear clustering and variation in fruit and leaf traits.
- Maslinic acid treatment showed a partial restoration of antioxidant defenses and reduction in reactive oxygen species levels following testicular ischemia-reperfusion injury in rats.
- Genetic diversity analysis revealed a north-south split with Dhofar populations forming a distinct lineage among wild olive accessions from Oman's mountains.
- MICOSAT F® microbial biostimulant treatment led to increased growth and altered carbon and nitrogen metabolism in olive trees, potentially enhancing their climate resilience.
- The study found that adjusting olive paste pH during malaxation influenced oil yield, phenolic content, and quality parameters of virgin olive oil.
- The study highlights that olive leaf extract exhibits multiple beneficial effects, including anti-inflammatory and anti-tumoral properties, though its role as an adjunct therapy in pediatric oncology remains to be fully elucidated.
- Cultivar-dependent responses to foliar fertilization varied in fruit size, quality indicators, and mineral composition across different olive cultivars.
- The study found that olive cultivars respond differently to Xylella fastidiosa infection, with resistant LECCINO showing targeted gene activation while susceptible OLIVA ROSSA exhibits widespread but ineffective reprogramming.
