Plants use many means to attract pollinators, including visual cues and odor. We investigated how nonpigment floral chemistry influences nectar removal, floral visitation, florivory, rates of outcrossing, and fitness through both male and female functions. We blocked expression of biosynthetic genes of the dominant floral attractant [benzyl acetone (Nachal1)] and nectar repellent [nicotine (Napmt1/2)] in all combinations in the native tobacco Nicotiana attenuata and measured their effects on… Expand
Nectar alkaloids decrease pollination and female reproduction in a native plant
TLDR
This work suggests that nectar alkaloids are more costly than beneficial in the authors' system, and that relatively small-scale spatial variation in trait effects and interactions could determine the selective impacts of traits such as nectar composition. Expand
Jasmonate signaling makes flowers attractive to pollinators and repellant to florivores in nature.
TLDR
It was revealed that silencing JA signaling resulted in flowers that produce less nectar and benzyl acetone, two pollinator-attractive traits, and flowers of defenseless plants were highly attacked by a suite of native herbivores, and damage to buds in native plants correlated negatively with their JA-Ile levels. Expand
Petunia flowers solve the defence/apparency dilemma of pollinator attraction by deploying complex floral blends.
TLDR
It is demonstrated that the emission of single floral-scent compounds can dramatically decrease damage from generalist florivores, and it is concluded that the complex blends that comprise floral scents are likely sculpted by the selective pressures of both pollinators and herbivores. Expand
Advertising to the enemy: enhanced floral fragrance increases beetle attraction and reduces plant reproduction.
TLDR
This study is the first to demonstrate that enhanced floral fragrance can increase the attraction of detrimental florvores and decrease plant reproduction, suggesting that florivory as well as pollination has shaped the evolution of floral scent. Expand
Phenotypic selection on floral scent: trade-off between attraction and deterrence?
TLDR
This work investigated phenotypic selection on floral scent and floral display using the rewarding orchid species Gymnadenia odoratissima to suggest different patterns of selection impact on different scent compounds, which may relate to the functions of compounds for attracting/deterring insects. Expand
Color and scent: how single genes influence pollinator attraction.
TLDR
This work reviews current knowledge about the biosynthetic pathways for floral color and scent production and their interaction at the genetic and biochemical levels and concerns the genes that underlie natural variation incolor and scent and how such genes affect pollinator preference, reproductive isolation, and ultimately speciation. Expand
Nectar Robbing: Ecological and Evolutionary Perspectives
TLDR
The evolutionary ecology of nectar robbing is reviewed from both the plant and animal perspective, and how plants may be able to deter robbers through morphological and chemical traits is detailed. Expand
Secondary compounds in floral rewards of toxic rangeland plants: impacts on pollinators.
TLDR
The biochemical, physiological, and behavioral mechanisms by which pollinators cope with secondary compound consumption are discussed, drawing parallels between pollinators and herbivores. Expand
How scent and nectar influence floral antagonists and mutualists
TLDR
Both scent and nectar increase outcrossing rates for three, separately tested, pollinators and both traits increase oviposition by a hawkmoth herbivore, with nectar being more influential than scent. Expand
Floral volatile organic compounds: Between attraction and deterrence of visitors under global change
TLDR
This work updates the current knowledge of four key aspects of floral emissions: the relative importance and interaction of olfactory signals and visual cues, the spatial and temporal patterns of emission in flowers, the attractive and defensive functions of floral volatiles and their interference, and the effects of global change on floral emissions and plant–pollinator interactions.

Making sense of nectar scents: the effects of nectar secondary metabolites on floral visitors of Nicotiana attenuata.
TLDR
It is hypothesize that nectar repellents optimize the number of flower visitors per volume of nectar produced, allowing plants to keep their nectar volumes small. Expand
Start making scents: the challenge of integrating chemistry into pollination ecology
TLDR
The historical and cultural reasons for this impasse between plant volatiles and pollination ecology are examined, focusing on the ways that questions in each field are addressed, and the potential for productive cross‐talk. Expand
Opportunistic out-crossing in Nicotiana attenuata (Solanaceae), a predominantly self-fertilizing native tobacco
TLDR
Even though moth pollination is rare and highly variable for this largely selfing plant, N. attenuata opportunistically employs a mixed-mating system that mediate gene flow when self-pollen is unavailable. Expand
Florivory: the intersection of pollination and herbivory.
TLDR
The approaches to studying florivory that are outlined may yield novel insights into floral and defence traits not illuminated by studies of pollination or herbivory alone. Expand
Single Gene–Mediated Shift in Pollinator Attraction in Petunia[W]
TLDR
Results show that changes in a single gene cause a major shift in pollination biology and support the notion that the adaptation of a flowering plant to a new pollinator type may involve a limited number of genes of large effect. Expand
The chemistry of defense and apparency in the corollas ofNicotiana attenuata
TLDR
Although N. attenuata's defensive and advertisement chemistries respond synchronously to some environmental stimuli, the flowers' chemical responses to pollinators and herbivores are distinct and the differences reflect their ecological roles. Expand
Nicotine's Defensive Function in Nature
TLDR
It is demonstrated that silencing pmt inhibits nicotine production, while the excess NA dimerizes to form anatabine, providing strong evidence that nicotine functions as an efficient defense in nature and highlights the value of transgenic techniques for ecological research. Expand
Allele substitution at a flower colour locus produces a pollinator shift in monkeyflowers
TLDR
Field studies indicate that an adaptive shift in pollinator preference may be initiated by a single major mutation at a single locus, YELLOW UPPER. Expand

TLDR
Molecular analysis of the genes that control secondary metabolite production underscores just how correct Kerner von Marilaun, Errera, and, particularly, Stahl were in their view. Expand

TLDR
Besides the phenylbutanones in rhubarb, BAS has been proposed to play a crucial role for the construction of the C6-C4 moiety of a variety of natural products such as medicinally important gingerols in ginger plant. Expand
