Study on Floral Syndrome and Breeding System of an Endangered Species Rhododendron nymphaeoides

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study divided the flowering process of Rhododendron nymphaeoides into five periods and systematically investigated the floral traits, pollen morphology and viability, optimal solid media for in vitro pollen germination, storage temperature screening, pollen–ovule ratio and hybridization index, stigma receptivity, the effects of different ...

Distribution of genetic diversity in wild European populations of prickly lettuce (Lactuca serriola): implications for plant genetic resources management [PDF]

, 2010
Genetic variation in Lactuca serriola, the closest wild relative of cultivated lettuce, was studied across Europe from the Czech Republic to the United Kingdom, using three molecular marker systems, simple sequence repeat (SSR, microsatellites), AFLP and

Effects of genotype × environment interactions on the morphological and genetic aspects of the seed characteristics of faba beans

The Plant Genome, Volume 18, Issue 4, December 2025.
Abstract Faba bean (Vicia faba L.) is one of the oldest cultivated crops in the world. It is the third most important feed grain legume globally, after soybean and lupin. It is an autogamous plant with a partial outcrossing rate ranging from 20% to 80%.

Linking self-incompatibility, dichogamy, and flowering synchrony in two Euphorbia species: alternative mechanisms for avoiding self-fertilization? [PDF]

PLoS ONE, 2011
Plant species have several mechanisms to avoid selfing such as dichogamy or a self-incompatibility response. Dichogamy in a single flower may reduce autogamy but, to avoid geitonogamy, plants must show flowering synchronization among all their flowers (i.

Pollen: ovule ratio and its relationship with other reproductive traits in some Passiflora species (Passifloraceae) [PDF]

, 2014
The pollen/ovule (P/O) ratio has been used as predictor of the reproductive system of angiosperms (lowest P/O values correspond to obligate autogamous species while the highest correlate with obligate xenogamous species) but it does not keep for all the ...

Genomic‐Guided Conservation Actions to Restore the Most Endangered Conifer in the Mediterranean Basin

Molecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT Species with extremely small population sizes are critically endangered because of reduced genetic diversity, increased inbreeding and hybridisation threats. Genomic tools significantly advance conservation by revealing genetic insights into endangered species, notably in monitoring frameworks.

Nolana balsamiflua (Gaudich.) Mesa (Solanaceae), un arbusto vulnerable del desierto de Atacama dependiente de polinizadores para producir semillas

Gayana: Botanica, 2019
Pollinator-dependency for reproduction is of great importance for plants. We evaluated the breeding system of Nolana balsamiflua, a threatened endemic shrub of the Atacama Desert, performing four pollination trials.

Pollination boilogy and breeding system of Eugenia discifera Gamble An endangered species of Western Ghats, India. [PDF]

, 2015
Knowledge of the pollination biology and breeding systems is very important for understanding the life history of long - lived tree species. In case of endangered species, the information may have implication for conservation practices.

Human‐Mediated Dispersal Routes Structure Sahara Mustard Genomics

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Humans have facilitated the spread and evolution of invasive species, a pattern that has accelerated with the globalisation of trade and societal development. Consequently, the invasiveness of a species may be determined not only by how many propagules and which genotypes are introduced, but also by its evolutionary history and how humans have

Wind pollination and propagule formation in Rhizophora mangle L. (Rhizophoraceae): resource or pollination limitation?

Anais da Academia Brasileira de Ciências, 2014
Rhizophora mangle is considered as a self-compatible mangrove, and is pollinated by wind and insects. However, there is no information about fruit production by autogamy and agamospermy and on the foraging behavior of its flower visitors.
