The Mediterranean basin represents one of the key hotspots in terms biodiversity and endemic floristic richness world (i.e., a reservoir plant biodiversity). With ongoing climate change, vegetation is increasingly exposed to different sources environmental stresses, such as drought, heat, solar irradiance. To cope with these severe abiotic beside morpho-anatomical traits, species enhance produc...
