To attract pollinating animals, plants display an elaborate array of color, form, and scent?but the ultimate reward for the pollinators is nectar, a complex sugary liquid with distinct composition across species. Nectar is produced in nectaries, secretory structures with diverse organization broadly distributed in plants. We are working to understand the developmental basis of nectary formation and nectar production. Using comparative genetics and genomic tools, the Nikolov Lab is identifying genes that control how and where the nectaries are built, and the mechanisms responsible for nectar synthesis and secretion. These findings will provide insight into a plant-animal mutualism important to agriculture and bee health, and will stimulate future applications to increase crop yield by enhancing the ecosystem services of pollinators.
