Parthenogenesis in scorpions: some history - new data

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2008
Parthenogenesis, a rare phenomenon in Chelicerates, apart from mites, is reviewed in scorpions, notably Tityus serrulatus Lutz & Mello from Brazil, Tityus columbianus (Thorell) from Colombia and Tityus metuendus Pocock from Peru and Brazil.

Facultative parthenogenesis in the burrowing mayfly, Ephoron eophilum (Ephemeroptera: Polymitarcyidae) with an extremely short alate stage

open access: yesEuropean Journal of Entomology, 2015
Facultative parthenogenesis is important for mayflies with short alate stages because females are able to reproduce without mating. We studied facultative parthenogenesis in Ephoron eophilum, a mayfly with an extremely short alate stage.

Diversity in the reproductive modes of European Daphnia pulicaria deviates from the geographical parthenogenesis. [PDF]

open access: yesPLoS ONE, 2011
Multiple transitions to obligate parthenogenesis have occurred in the Daphnia pulex complex in North America. These newly formed asexual lineages are differentially distributed being found predominantly at high latitudes.

Facultative parthenogenesis validated by DNA analyses in the green anaconda (Eunectes murinus). [PDF]

open access: yesPLoS ONE, 2017
In reptiles, the mode of reproduction is typically sexual. However, facultative parthenogenesis occurs in some Squamata, such as Komodo dragon (Varanus komodoensis) and Burmese python (Python bivittatus).

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

Meiosis genes in Daphnia pulex and the role of parthenogenesis in genome evolution

open access: yesBMC Evolutionary Biology, 2009
Background Thousands of parthenogenetic animal species have been described and cytogenetic manifestations of this reproductive mode are well known. However, little is understood about the molecular determinants of parthenogenesis.

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 ...

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.
