Floral specialization for beetle pollination and its implications for pollen dispersal in an African orchid

American Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Premise Pollination by beetles is relatively rare in orchids, and this has been attributed to the clumsy behavior of beetles being unsuitable for the precise pollen transfer mechanisms that characterize the orchid family. We investigated floral specialization for beetle pollination in the rare fire‐dependent South African orchid Disa elegans ...

American highbush cranberry maintains strong population structure despite naturalization of Eurasian relatives in North America

American Journal of Botany, Volume 112, Issue 11, November 2025.
Abstract Premise The proper classification of taxa is often debated, particularly when organisms lack qualitative diagnostic traits. Highbush cranberry taxa (Viburnum spp.) have been the subject of such disputes since their characterization by 18th‐ and 19th‐century botanists. Despite their allopatric distributions—V.

Influence of clonal growth on selfing rate in Vaccinium myrtillus L.

, 2008
Clonal growth, which allows the multiplication of flowering shoots of the same genet, can lead to a large floral display and may thus increase the rate of selfing through geitonogamy as a consequence of an increase in the number of successively visited ...

Reproductive biology of two sympatric species of Polyalthia (annonaceae) in Sri Lanka. II. Breeding systems and population genetic structure [PDF]

, 2006
The breeding systems of two sympatric species, Polyalthia coffeoides and Polyalthia korinti (Annonaceae), are assessed using a range of approaches, including controlled pollination experiments and analysis of inter-simple sequence repeat markers within ...

Floral Handedness in Mormodes Orchids: Revisiting Charles Darwin's Observations

Biotropica, Volume 57, Issue 6, November 2025.
In this study, we scrutinized floral enantiostyly in Mormodes orchids, a unique trait within Orchidaceae first observed by Charles Darwin. We hypothesize how intricate column twisting drives strategic pollinarium placement onto opposite sides of the thorax of male euglossine bees, enhancing cross‐pollination.

Comparison of varying pollen source on productivity of sour cherry (Prunus cerasus L.) cultivars

International Journal of Horticultural Science, 2010
Fruit set of five sour cherry cultivars (‘Újfehértói fürtös’, ‘Éva’, ‘Petri’, ‘Pándy 279‘ and ‘Csengôdi’) of eight years-old trees grown in Újfehértó, located in the Eastern north part of Hungary have been studied over two years (2008 & 2009).

Reproductive biology of the threatened species Furcraea parmentieri (Aspargaceae)

Botan‪ical Sciences, 2017
Background: Reproductive traits are features of a species’ biology that may determine its rarity, as they affect its genetic diversity and structure, as well as its population dynamics.

Clonal longevity and the enigmatic flowering of woody bamboos are associated with rates of protein evolution

Journal of Integrative Plant Biology, Volume 67, Issue 11, Page 2945-2963, November 2025.
Examining data from 148 Bambusoideae and Pooideae species showed elevated protein evolution rates in highly cloned woody bamboos, providing evidence for an association between protein evolution and life‐history traits in plants with contrasting reproductive modes. ABSTRACT Rates of protein evolution (dN/dS) vary widely across the tree of life.

Fitness Effects of Somatic Mutations on Mimulus aurantiacus Progeny [PDF]

, 2022
Unlike animals, plants possess the unique ability to pass on mutations to progeny that arise both through meiotic (germline) and mitotic (somatic) division.

Anther mimicry in an African orchid pollinated by pollen‐feeding beetles

Plant Biology, Volume 27, Issue 6, Page 1071-1078, October 2025.
Beetles chew the fleshy yellow tips of an orchid's petals and pollinate its flowers, representing a novel case of pollen‐seeking beetles being deceived through anther mimicry. Abstract Flowers of many species have yellow markings that appear to mimic anthers or pollen and attract the attention of pollen‐seeking insects (usually female bees).
