Secondary Metabolites in Nectar-Mediated Plant-Pollinator Relationships

Plants, 2023
In recent years, our understanding of the complex chemistry of floral nectar and its ecological implications for plant-pollinator relationships has certainly increased.

Supplementing Blood Diet With Plant Nectar Enhances Egg Fertility in Stomoxys calcitrans [PDF]

Frontiers in Physiology, 2021
Stomoxys calcitrans (stable fly) is a cosmopolitan biting fly of both medical and veterinary importance. Unlike blood-feeding-related behavior of stable fly, its plant feeding, the fitness value, and the S.

Effects of shading, fertilization, and irrigation on floral display and honey yield in Agastache rugosa in controlled pot culture [PDF]

Frontiers in Plant Science
Sustainable cultivation of Agastache rugosa requires quantitative guidance on how to balance ornamental floral display with nectar-mediated honey production under realistic limitations in light, nutrients, and water.

Comparison of sugars, iridoid glycosides and amino acids in nectar and phloem sap of Maurandya barclayana, Lophospermum erubescens, and Brassica napus. [PDF]

PLoS ONE, 2014
BACKGROUND: Floral nectar contains sugars and amino acids to attract pollinators. In addition, nectar also contains different secondary compounds, but little is understood about their origin or function. Does nectar composition reflect phloem composition,

Free amino acids in nectar: its composition and variability among bat-pollinated plants

Revista Mexicana de Biodiversidad, 2021
Regardless of the low concentrations at which amino acids are present in floral nectar of bat-pollinated plants, their role as nectar flavor providers and their influence on bats’ foraging decisions have been recognized.

Variation in nectar quality across 34 grassland plant species [PDF]

Plant Biology, 2021
ABSTRACT Floral nectar is considered the most important floral reward for attracting pollinators. It contains large amounts of carbohydrates besides variable concentrations of amino acids and thus represents an important food source for many pollinators. Its nutrient content and composition can, however, strongly vary within and between plant species.

Comparative analyses of the metabolite and ion concentrations in nectar, nectaries, and leaves of 36 bromeliads with different photosynthesis and pollinator types

Frontiers in Plant Science, 2022
Floral nectar contains mainly sugars as well as smaller amounts of amino acids and further compounds. The nectar composition varies between different plant species and it is related to the pollination type of the plant. In addition to this, other factors

A Decrease in the Staminode-Mediated Visitor Screening Mechanism in Response to Nectar Robbers Positively Affects Reproduction in Delphinium caeruleum Jacq. ex Camb. (Ranunculaceae)

Biology, 2022
Nectar-robbing insects, which are frequently described as cheaters in plant–pollinator mutualisms, may affect plant reproductive fitness by obtaining nectar rewards without providing pollination services.

Nectar microbes may indirectly change fruit consumption by seed-dispersing birds

Basic and Applied Ecology, 2023
An increasing number of recent studies show that nectar-inhabiting microorganisms influence plant fitness by mediating interactions between plants and pollinators.
