PLANTS,POLLINATORS,AND BIODIVERSITY:THESTATUSQUO Plant-pollinator coevolution has played a crucial role in shaping the biodiversity of ecosystems that we know today.Moreover,plants and pollinators are key to agriculture,contributing to the production of most fruits and vegetables necessary for healthy human diets.Unfortunately,over the last decades,there is mounting evidence of pollinator decline all over the world,which constitutes a major threat to food security(European Commission,2020).To pollinators,nectar and pollen are the main rewards:pollen is essentially their only source of proteins,lipids,and vitamins,while nectar is a carbohydrate-rich solution that they use to fuel somatic functions(Ollerton,2021).However,nectar is much more than just a sweet solution:it comprises a plethora of secondary metabolites and volatiles of major importance for plant-pollinator communication.Unfortunately,by neglecting these traits and reducing genetic diversity,plant breeding has potentially increased the risk of losing the traits beneficial to pollinators.
