Mechanisms and molecular basis of the effect of natural oils on the development and resilience of plants aimed at the eco- sustainable production of vegetable species.

Natural substances represent an alternative to mitigate the excessive use of chemicals, giving contribution to eco-sustainable agriculture. Essential oils have been extensively applied in organic farming with effective controls against plant diseases due to both pathogens and pests. However, studies are needed to understand plant responses at the physiological and molecular levels in order to unravel fundamental mechanisms, optimize oil usage and preserve crop quality. Moreover, studies on the effects of oil on plant organ differentiation and development are still in their infancy. Within a context of circular bioeconomy, a research program has been developed (industrial doctorate and the project TOP CROP – Gruppi di Ricerca by Regione Lazio) to study the effects of lavender and jasmine oils on flowers of Brassicaceae using a translational biology approach with model (A. thaliana) species and local crops (Brassica rapa sylvestris, cime di rapa) through lab and open field experiments. Here, we report the project outline and preliminary results regarding the oil effects on flower opening.
