Self-Pollinated Types and Ecological Adaptations of the Desert Plant Gymnocarpos przewalskii [PDF]

open access: yesPlants
In desert plants, outcrossing is frequently limited by pollinator scarcity, leading to a certain percentage of self-fertilization. However, research on the ecological adaptations of self-fertilized seeds remains limited.

Phylogenetic Relatedness Determines Heterospecific Pollen–Pistil Compatibility and Reproductive Outcome in the Apocarpous Species Sagittaria trifolia (Alismataceae) [PDF]

open access: yesEcology and Evolution
Pollinator sharing among coflowering plants can reduce plant fitness through heterospecific pollen (HP) deposition. Compatible HP is expected to cause stronger reproductive interference, but the factors determining HP–pistil compatibility and its ...

Assessment of the breeding system in the Algerian narrow coastal endemism Anacyclus linearilobus (Anthemideae, Asteraceae)

open access: yesAnales del Jardín Botánico de Madrid, 2022
The breeding system of Anacyclus linearilobus, an annual and endemic species restricted to dune ecosystems of the Algerian coast were assessed through the effect of self-fertilization and intra- and inter-population artificial crosses on the probability

Range expansions of sexual versus asexual organisms: Effects of reproductive assurance and migration load

open access: yesJournal of Evolutionary Biology, 2023
It is generally considered that sexual organisms show faster evolutionary adaptation than asexual organisms because sexuals can accumulate adaptive mutations through recombination.

The explosive flowers of Marsypianthes chamaedrys (Lamiaceae) resort to self-pollination and improve reproduction

open access: yesActa Botânica Brasílica, 2022
Explosive pollination includes a rapid release of floral sexual elements that are enclosed in modified petals, and a subsequent contact with pollinators’ body.

A test of the reproductive assurance hypothesis in Ipomoea hederacea: does inbreeding depression counteract the benefits of self-pollination?

open access: yesAmerican-Eurasian journal of botany, 2021
PREMISE Darwin proposed that self-pollination in allegedly outcrossing species might act as a reproductive assurance mechanism when pollinators or mates are scarce; however, in natural populations, the benefits of selfing may be opposed by seed ...

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.
