Haploidy in Tobacco Induced by PsASGR-BBML Transgenes via Parthenogenesis

Genes, 2020
Background: Engineering apomixis in sexually reproducing plants has been long desired because of the potential to fix hybrid vigor. Validating the functionality of genes originated from apomictic species that contribute to apomixis upon transfer to ...

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

PLoS 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)

Insects, 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

Genetic Dissection of Apomixis in Dandelions Identifies a Dominant Parthenogenesis Locus and Highlights the Complexity of Autonomous Endosperm Formation

Genes, 2020
Apomixis in the common dandelion (Taraxacum officinale) consists of three developmental components: diplospory (apomeiosis), parthenogenesis, and autonomous endosperm development.

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

BMC 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.

Geographic parthenogenesis and plant-enemy interactions in the common dandelion

BMC Evolutionary Biology, 2013
Background Many species with sexual and asexual variants show a pattern of geographic parthenogenesis where asexuals have broader and higher-latitude distribution than sexuals.

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

Plants, 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.

Identification of Parthenogenesis-Inducing Effector Proteins in Wolbachia

Genome Biology and Evolution
Bacteria in the genus Wolbachia have evolved numerous strategies to manipulate arthropod sex, including the conversion of would-be male offspring to asexually reproducing females.

“Jack‐of‐all‐trades” is parthenogenetic

Ecology and Evolution, 2022
Sex is evolutionarily more costly than parthenogenesis, evolutionary ecologists therefore wonder why sex is much more frequent than parthenogenesis in the majority of animal lineages. Intriguingly, parthenogenetic individuals and species are as common as

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

PLoS 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
