Nectary development in Cleome violacea

Frontiers in Plant Science, 2023
Nectaries are a promising frontier for plant evo-devo research, and are particularly fascinating given their diversity in form, position, and secretion methods across angiosperms.

Unravelling the Homology between Calycine Glands in Malpighiales: New Data from Basal Malpighiaceae [PDF]

Plants
Discussing homology relationships among secretory structures remains a relatively underexplored area in botanical research. These structures are widely dispersed within Malpighiales, one of the largest orders of eudicots.

Metabolic and transcriptomic analyses of nectaries reveal differences in the mechanism of nectar production between monocots (Ananas comosus) and dicots (Nicotiana tabacum) [PDF]

BMC Plant Biology
Background Nectar is offered by numerous flowering plants to attract pollinators. To date, the production and secretion of nectar have been analyzed mainly in eudicots, particularly rosids such as Arabidopsis.

Nectary structure and its taxonomic significance in the genus Matthiola [PDF]

رستنی‌ها, 2022
Nectary morphology of Matthiola species (Brassicaceae) in the Flora Iranica area was examined using a stereomicroscope to evaluate its systematic significance and assess infrageneric relationships.

Comparative Nectary Morphology across Cleomaceae (Brassicales)

Plants, 2023
Floral nectaries have evolved multiple times and rapidly diversified with the adaptive radiation of animal pollinators. As such, floral nectaries exhibit extraordinary variation in location, size, shape, and secretory mechanism.

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

The Genetic Control of Nectary Development [PDF]

Trends in Plant Science, 2021
Nectar is the most important reward offered by flowering plants to pollinators for pollination services. Since pollinator decline has emerged as a major threat for agriculture, and the food demand is growing globally, studying the nectar gland is of utmost importance.

Flower and Spikelet Construction in Rapateaceae (Poales)

Frontiers in Plant Science, 2022
The family Rapateaceae represents an early-divergent lineage of Poales with biotically pollinated showy flowers. We investigate developmental morphology and anatomy in all three subfamilies and five tribes of Rapateaceae to distinguish between ...

Structure and histology of extrafloral nectaries of tropical species in a mexican rain forest

Bioscience Journal, 2016
Although there is a large diversity of plant species with extrafloral nectaries, histological detail of these glands is poorly documented in tropical rain forest species. We characterized extrafloral nectaries using digital photographs, scanning electron

Morphological study of floral nectaries in Euonymus and the probable origin of the echinate fruit surface

Plant Diversity, 2018
A conspicuous nectary disk is common but has a distinguishing morphology in the cosmopolitan genus Euonymus. Our study focuses on the morphology of floral nectaries in 21 representatives of Euonymus and Glyptopetalum.
