Assessment of Pollen Production, Pollen Viability, Autofertility and Paternal Success in Faba Bean (Vicia faba L.) for Better Exploitation of Grain Yield Heterosis

open access: yesPlant Breeding, EarlyView.
ABSTRACT In animal‐pollinated plants, pollen dispersal depends on several plant and animal characteristics that can influence the paternal success of a plant. Paternal success affects the genetic contribution of a genotype to the next generation, which is relevant to plant breeding.

The mixed mating system of a widespread weed: the case of Argemone ochroleuca Sweet (Papaveraceae)

open access: yesBotan‪ical Sciences, 2022
Background: Argemone ochroleuca is a worldwide invasive weed but is also highly valuable for their chemical compounds. Knowledge about its reproduction will help create plans for its control or its propagation. Questions: Does A.

A case of budding speciation in the California Floristic Province and infraspecific divergence in Abronia villosa

open access: yesAmerican Journal of Botany, Volume 113, Issue 7, July 2026.
Abstract Premise Budding speciation occurs when peripheral populations adapt to local ecological conditions and “bud” off from a widespread progenitor species. Traditionally regarded as rare because of its sympatric and parapatric nature, budding speciation is largely understudied.

Preferential reproduction mode of hermaphrodite papaya plant (Carica papaya L; Caricaceae) Modo de reprodução preferencial de plantas hermafroditas de mamoeiro (Carica papaya L; Caricaceae)

open access: yesRevista Brasileira de Fruticultura, 2009
This research was done to study the reproductive system of papaya hermaphrodite plant based on the histochemical nature of pollen grain, stigma receptivity, in vivo pollen grain germination and pollen:ovule ratio.

Leaf Fungal Microbiome Is Modulated by Interspecific Hybridization Events Between Coffea Species

open access: yesPhysiologia Plantarum, Volume 178, Issue 4, July/August 2026.
ABSTRACT Increasing attention has been given to the host phylogeny and domestication roles in shaping plant‐associated microbiomes. However, the interspecific effects of hybridization on microbial communities remain poorly understood. We investigated the effects of interspecific hybridization on the composition, diversity, ecological organization, and ...

The dynamics of Listera ovata populations on mineral islands in the Biebrza National Park

open access: yesActa Societatis Botanicorum Poloniae, 2014
Observations of two isolated populations of Listera ovata (Oparzelisko and Zabudnik) were conducted for 7 years in the Biebrza National Park. The studied populations differed in size, proportion of flowering individuals and effectiveness of reproduction.

The pollination of Epipactis Zinn, 1757 (Orchidaceae) species in Central Europe – the significance of chemical attractants, floral morphology and concomitant insects

open access: yesActa Societatis Botanicorum Poloniae, 2011
A series of studies on pollination biology of the Epipactis atrorubens (Hoffm.) Besser, E. purpurata Sm., and E. palustris (L.) Crantz populations was conducted in Poland, Lithuania and Czech Republic between 2003 and 2010.

Genomic Offset Analyses: Mind Your Climate Variables

open access: yesGlobal Change Biology Communications, Volume 1, Issue 2, June 2026.
Recent methods based on genomic offset (GO) statistics aim to quantify the risk of non‐adaptation of populations to future climates. This study assesses how well genomic offset values correspond to population variation in fitness, depending on the methods and climate data used.

Adaptive floral traits that impact stigma pollen load and seed production in Penstemon digitalis (Plantaginaceae)

open access: yesNordic Journal of Botany, Volume 2026, Issue 6, June 2026.
Penstemon digitalis is an early spring‐flowering species of the northwest Missouri prairie community, a period often characterized by low and unpredictable bee visitation. We conducted an experimental field study to evaluate how pollinator‐mediated pollen transfer and floral longevity interact to influence pollen acquisition and seed production.
