Volatile emissions of scented Alstroemeria genotypes are dominated by terpenes, and a myrcene synthase gene is highly expressed in scented Alstroemeria flowers
(2012)
Native to South America, Alstroemeria flowers are known for their colourful tepals, and Alstroemeria hybrids are an important cut flower. However, in common with many commercial cut flowers, virtually all the commercial ...
Molecular and morphological characterization of new interspecific hybrids of alstroemeria originated from A. caryophylleae scented lines
(Universidad San Sebastián, 2019)
Alstroemeria is a genus native to South America from which many varieties of ornamental plants have been developed and introduced into the market. Interspecific hybridization followed by embryo rescue has been one of the ...
Generalized pollination system: are floral traits adapted to different pollinators?
(Kluwer Academic Publishers, 2014)
Flowers that are pollinated both during the day and at night could exhibit two different groups of pollinators and produce two different sets of attractants and rewards. We explored the patterns of emission of flower scents ...
Spatial and temporal variation in volatile composition suggests olfactory division of labor within the trap flowers of Aristolochia gigantea
(Elsevier Gmbh, 2017-07)
The olfactory components of floral advertisement can be complex, often showing dynamic patterns of emission and chemical composition that may reflect diverse functions related to pollination. In this study we investigated ...
Ultrastructure of the corona of scented and scentless flowers of Passiflora spp. (Passifloraceae)
(Elsevier Gmbh, 2007-05-10)
To know thoroughly the structure and function of the corona of Passiflora, the anatomy and ultrastructure of two species were analysed in relation to the emission of odour perceivable by humans: a scented one, P. caerulea ...
A simple floral fragrance and unusual osmophore structure in Cyclopogon elatus (Orchidaceae)
(Wiley, 2008-10)
We studied gland morphology, anatomy and the chemical composition of the floral fragrance in the sweat bee-pollinated orchid Cyclopogon elatus.This is apparently the first such analysis for any Cyclopogon species, and one ...
The role of fetid olfactory signals in the shift to saprophilous fly pollination in Jaborosa (Solanaceae)
(Springer, 2019-06)
Floral scents can act as important contributing factors to plant reproductive isolation mediated by pollinators. Plants may utilize fetid floral odors that specifically lure saprophilous flies seeking high protein content ...
Quantitative levels of Deficiens and Globosa during late petal development show a complex transcriptional network topology of B function
(Wiley Blackwell Publishing, Inc, 2012-08)
The transcriptional network topology of B function in Antirrhinum, required for petal and stamen development, is thought to rely on initial activation of transcription of DEFICIENS (DEF) and GLOBOSA (GLO), followed by a ...
I’ve been robbed! – Can changes in floral traits discourage bee pollination?
(2019-11-01)
Some floral visitors collect nectar by piercing flower external whorls, acting as nectar robbers. They leave robbery vestiges, which can cause changes in floral characteristics, including physical and chemical signals that ...
