The role of jasmonates in floral nectar secretion. [PDF]
PLoS ONE, 2010 Plants produce nectar in their flowers as a reward for their pollinators and most of our crops depend on insect pollination, but little is known on the physiological control of nectar secretion.

Floral nectar guide patterns discourage nectar robbing by bumble bees. [PDF]
PLoS ONE, 2013 Floral displays are under selection to both attract pollinators and deter antagonists. Here we show that a common floral trait, a nectar guide pattern, alters the behavior of bees that can act opportunistically as both pollinators and as antagonists ...

Yeasts in floral nectar: a quantitative survey [PDF]
Annals of Botany, 2009 One peculiarity of floral nectar that remains relatively unexplored from an ecological perspective is its role as a natural habitat for micro-organisms. This study assesses the frequency of occurrence and abundance of yeast cells in floral nectar of insect-pollinated plants from three contrasting plant communities on two continents.

Nectar biosynthesis is conserved among floral and extrafloral nectaries [PDF]
Plant Physiology, 2021 AbstractNectar is a primary reward mediating plant–animal mutualisms to improve plant fitness and reproductive success. Four distinct trichomatic nectaries develop in cotton (Gossypium hirsutum), one floral and three extrafloral, and the nectars they secrete serve different purposes.

How scent and nectar influence floral antagonists and mutualists
eLife, 2015 Many plants attract and reward pollinators with floral scents and nectar, respectively, but these traits can also incur fitness costs as they also attract herbivores.

Scientific ReportsBeyond its essential role in plant–pollinator interactions, floral nectar serves as habitats for diverse fungal communities that can influence plant–animal mutualism.

Nectar Theft and Floral Ant-Repellence: A Link between Nectar Volume and Ant-Repellent Traits? [PDF]
PLoS ONE, 2012 As flower visitors, ants rarely benefit a plant. They are poor pollinators, and can also disrupt pollination by deterring other flower visitors, or by stealing nectar. Some plant species therefore possess floral ant-repelling traits. But why do particular species have such traits when others do not?

Zooming-in on floral nectar: a first exploration of nectar-associated bacteria in wild plant communities [PDF]
FEMS Microbiology Ecology, 2012 Floral nectar of some animal-pollinated plants usually harbours highly adapted yeast communities which can profoundly alter nectar characteristics and, therefore, potentially have significant impacts on plant reproduction through their effects on insect foraging behaviour.

Plant Diversity, 2023 Floral trait variation may help pollinators and nectar robbers identify their target plants and, thus, lead to differential selection pressure for defense capability against floral antagonists.

Frontiers in Plant Science, 2022 Many flowers are fed on by florivores, but we know little about if and how feeding on flowers affects their visual and chemical advertisement and nectar resource, which could disrupt pollination.
