Transcriptomic and microstructural analyses in Liriodendron tulipifera Linn. reveal candidate genes involved in nectary development and nectar secretion

open access: yesBMC Plant Biology, 2019
Background Nectar is a major floral attractant and reward for insects that ensures pollination. Liriodendron, a genus of the Magnoliaceae family, includes only two relict species, L. chinense and L.

The role of habitat simplification and seasonality in shaping interactions between ants, plants and herbivores in a neotropical savanna

open access: yesEcological Entomology, Volume 51, Issue 2, Page 381-394, April 2026.
We evaluated how chronic anthropogenic disturbances (CAD) and seasonal variation influence interactions between ants and plants with extrafloral nectaries (EFN's), with emphasis on the responses of ants, herbivores, and plants. Ant and herbivore diversity remained stable across seasons in the preserved cerrado, whereas the pasture had higher ant ...

Origin and ontogeny of the extrafloral nectaries associated to the inflorescences of Vigna candida and Vigna caracalla (Leguminosae, Phaseoleae) [PDF]

open access: yes, 2015
The morphology , ontogeny and secretion of the extrafloral nectaries (EFNs) in the inflorescences of Vigna candida and Vigna caracalla were studied. The node s along the inflorescences were processed with standard techniques for light as well as scanning

Comparative micromorphology and anatomy of flowers and floral secretory structures in two Viburnum species [PDF]

open access: yes, 2016
In entomogamous plants, the presence and function of floral secretory structures, whose main role is to attract pollinators, is strictly associated with the pollination ecology and hence the reproductive success of the plant.

Neglected Floral Visitors in the Galapagos Islands: Understanding the Structure of Ant‐Flower Interaction Networks

open access: yesJournal of Applied Entomology, Volume 150, Issue 3, Page 321-332, April 2026.
ABSTRACT Ant‐flower interactions are prevalent in many ecosystems, yet their ecological significance remains poorly understood, particularly in isolated systems like the Galapagos Islands, where unique biotic assemblages create distinct interaction networks.

The comparison of nectaries structure of some varieties of ornamental apple

open access: yesActa Agrobotanica, 2012
The study of floral nectary structures of thirteen ornamental apple cultivars examined using light microscope (MS) and scanning electron microscope (SEM) was performed.

SUPERMAN, a regulator of floral homeotic genes in Arabidopsis [PDF]

open access: yes, 1992
We describe a locus, SUPERMAN, mutations in which result in extra stamens developing at the expense of the central carpels in the Arabidopsis thaliana flower.

The gynoecium structure in Dracaena fragrans (L.) Ker Gawl., Sansevieria parva N.E. Brown and S. trifasciata Prain (Asparagaceae) with special emphasis on the structure of the septal nectary [PDF]

open access: yes, 2013
In the gynoecium of Dracaena fragrans, Sansevieria parva and S. trifasciata, the vertical zonality of the ovary, the structural zonality of the gynoecium following Leinfellner, and the zonality of the septal nectary were studied.
