A Role for Differential Glycoconjugation in the Emission

A role for differential glycoconjugation in the emission of phenylpropanoid volatiles from ripening tomato fruit ( Solanum lycopersicum ) upon fruit tissue disruption has been discovered in this study Application of a multiinstrumental analytical platform for metabolic profiling of fruits from a diverse collection of tomato cultivars revealed that emission of three discriminatory

Scent matters: differential contribution of scent to

Floral scent can be an important contributor to pollination syndrome and in certain cases scent composition can be a better predictor of the type of pollinator than morphological floral traits (Gong et al 2015) Floral volatiles can act as both a long-distance and

Floral volatile organic compounds: Between attraction and

Feb 20 2013Other flowers emit volatile blends that resemble the odours of carrion or dung to attract pollinators (Niet et al 2011 Urru et al 2011) Male euglossine bees are attracted to and collect floral volatiles from particular species of orchids to attract females (Eltz et al 1999 Bemb 2004) Some of these relationships are very specific

Three floral volatiles contribute to differential

Flowering plants employ a wide variety of signals including scent to attract the attention of pollinators In this study we investigated the role of floral scent in mediating differential attraction between two species of monkeyflowers ( Mimulus ) reproductively isolated by pollinator preference The emission rate and chemical identity of floral volatiles differ between the bumblebee

Evolution and diversity of floral scent chemistry in the

In sum the role of each floral volatile remains unknown and floral volatiles may experience multiple selective forces and contribute differentially to pollinator attraction and plant fitness Manipulative experiments are needed to understand fully the role of scent traits and neurophysiological approaches may reveal how the olfactory system

Volatile Ester Formation in Roses Identification of an

Volatile Acetate Esters Are Major Constituents of "Fragrant Cloud" Floral Scent The levels of volatile acetate esters emitted from flower buds (stages 1 and 2) of "Fragrant Cloud" roses are very low (0 4 μg per flower per 24 h and 0 2 μg per flower per 24 h respectively) and consist almost exclusively of cis-3-hexenyl acetate (Fig (Fig 2A) 2 A)

Is Anopheles gambiae attraction to floral and human skin

Mosquitoes use odours to find energy resources blood hosts and oviposition sites While these odour sources are normally spatio-temporally segregated in a mosquito's life history here this study explored to what extent a combination of flower- and human-mimicking synthetic volatiles would attract the malaria vector Anopheles gambiae sensu stricto (s s ) In the laboratory and in large (80

Contribution of CoA Ligases to Benzenoid Biosynthesis in

Biosynthesis of benzoic acid from Phe requires shortening of the side chain by two carbons which can occur via the β-oxidative or nonoxidative pathways The first step in the β-oxidative pathway is cinnamoyl-CoA formation likely catalyzed by a member of the 4-coumarate:CoA ligase ([4CL][1]) family that converts a range of trans -cinnamic acid derivatives into the corresponding CoA thioesters
