Penetrance of symbiont-mediated parthenogenesis is driven by reproductive rate in a parasitoid wasp [PDF]

open access: yesPeerJ, 2017
Trichogramma wasps are tiny parasitoids of lepidopteran eggs, used extensively for biological control. They are often infected with the bacterial symbiont Wolbachia, which converts Trichogramma to an asexual mode of reproduction, whereby females develop ...

The Incidence of Wolbachia Bacterial Endosymbiont in Bisexual and Parthenogenetic Populations of the Psyllid Genus Cacopsylla (Hemiptera, Psylloidea)

open access: yesInsects, 2021
Wolbachia is one of the most common intracellular bacteria; it infects a wide variety of insects, other arthropods, and some nematodes. Wolbachia is ordinarily transmitted vertically from mother to offspring and can manipulate physiology and reproduction

Identifying and Engineering Genes for Parthenogenesis in Plants

open access: yesFrontiers in Plant Science, 2019
Parthenogenesis is the spontaneous development of an embryo from an unfertilized egg cell. It naturally occurs in a variety of plant and animal species.

Parthenogenesis and the Evolution of Anisogamy [PDF]

open access: yesCells, 2021
Abstract Recently, it was pointed out [1] that classic models for the evolution of anisogamy do not take into account the possibility of parthenogenetic reproduction, even though sex is facultative in many relevant taxa (e.g. algae) that harbour both anisogamous and isogamous species.

Facultative parthenogenesis in California condors [PDF]

open access: yes, 2021
Parthenogenesis is a relatively rare event in birds, documented in unfertilized eggs from columbid, galliform, and passerine females with no access to males.

Parthenogenesis in a captive Asian water dragon (Physignathus cocincinus) identified with novel microsatellites.

open access: yesPLoS ONE, 2019
Reptiles show varying degrees of facultative parthenogenesis. Here we use genetic methods to determine that an isolated, captive female Asian water dragon produced at least nine offspring via parthenogenesis. We identified microsatellites for the species

Variability of Reproduction Pathways in the Central-European Populations of Hawthorns with Emphasis on Triploids

open access: yesPlants, 2022
The role of apomeiosis, parthenogenesis, and pseudogamy in the asexual reproduction of some plant groups has not been fully elucidated in relation to species diversification.

Sperm-Dependent Parthenogenesis and Hybridogenesis in Teleost Fishes

open access: yes, 2009
In so-called unisexual teleost fishes, a broad spectrum of evolutionaty stages with varying amounts of sexual elements has evolved. These range from pure sperm-dependent parthenogenesis (gynogenesis) without or with different amounts of paternal leakage ...

Evidence of parthenogenetic populations from the Paratanytarsus laccophilus species group (Diptera: Chironomidae) in the Alaskan Arctic

open access: yesCHIRONOMUS Journal of Chironomidae Research, 2020
Parthenogenesis, reproduction without fertilization, is not common in the Chironomidae (Diptera), a family of insects with more than 6,000 described species.
