Colleters, Extrafloral Nectaries, and Resin Glands Protect Buds and Young Leaves of Ouratea castaneifolia (DC.) Engl. (Ochnaceae) [PDF]
Plants, 2021 Buds usually possess mechanical or chemical protection and may also have secretory structures. We discovered an intricate secretory system in Ouratea castaneifolia (Ochnaceae) related to the protection of buds and young leaves.

Nectar biosynthesis is conserved among floral and extrafloral nectaries. [PDF]
Plant Physiol, 2021 AbstractNectar is a primary reward mediating plant–animal mutualisms to improve plant fitness and reproductive success. Four distinct trichomatic nectaries develop in cotton (Gossypium hirsutum), one floral and three extrafloral, and the nectars they secrete serve different purposes.

Apoplasmic barrier in the extrafloral nectary of Citharexylum myrianthum (Verbenaceae)
Planta, 2021 The cytological changes underlying the formation of an apoplasmic barrier in the multi-layered extrafloral nectaries of Citharexylum myrianthum are compatible with the synthesis, transport and deposition of suberin. In terms of ontogenesis and function, the intermediate layers of these nectaries are homologous with the stalks of nectar-secreting ...

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

Negative effects of ant-plant interaction on pollination: costs of a mutualism
Sociobiology, 2021 The mutualism of ants and extrafloral nectary (EFN)-bearing plants is known to reduce rates of herbivory. However, ants may have negative impacts on other mutualisms such as pollination, constituting an indirect cost of a facultative mutualism.

Extrafloral nectaries in Combretaceae: morphology, anatomy and taxonomic significance
Bothalia: African Biodiversity & Conservation, 2004 Extrafloral nectaries (EFNs) in members of the Combretaceae are nectaries not involved with pollination and occurring on vegetative structures; they are believed to attract ants to protect plants against herbivorv by other insects.

Towards an attract-and-reward strategy: evaluating nectar resources and HIPVs under laboratory conditions to enhance Aphelinus mali parasitism activity, a key parasitoid of Eriosoma lanigerum. [PDF]
Pest Manag SciEuphorbia segetalis is a promising attractant insectary plant for Aphelinus mali. Meanwhile, Vicia faba and Vicia sativa are a promising nectar resource to sustain the parasitoid in early spring when the population of Eriosoma lanigerum is low, and honeydew is scarce.

Water availability shapes temporal patterns of extrafloral nectar secretion and ant visitation to a Neotropical legume. [PDF]
Plant Biol (Stuttg)Drought duration affects ant–plant interactions: extrafloral nectar quality initially increases and subsequently declines, and ant interaction patterns closely track these nectar dynamics. Abstract Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners.
