First report of recurrent parthenogenesis as an adaptive reproductive strategy in the endangered common smooth-hound shark Mustelus mustelus [PDF]
Scientific ReportsParthenogenesis, or virgin birth, describes a mode of reproduction where an egg develops into an offspring without fertilization, and is observed across various vertebrate taxa, excluding mammals.

Peer Community Journal, 2023 Transitions from obligate sex to obligate parthenogenesis have occurred repeatedly across the tree of life. Whether these transitions occur abruptly or via a transient phase of facultative parthenogenesis is rarely known.

Influence of Phase Change on Parthenogenesis in the Migratory Locust: A Behavioral Analysis [PDF]
InsectsThe migratory locust (Locusta migratoria), is a destructive pest in agriculture and ecological conservation, characterized by its unique phase polyphenism (phase change).

Protein Kinase A Regulates the Cell Cycle to Affect the Induction Rate in the Parthenogenetic Reproduction of the Silkworm, Bombyx mori [PDF]
CellsProtein kinase A (PKA), commonly referred to as cAMP-dependent protein kinase, exists as a heterotetramer composed of two catalytic (C) and regulatory subunits (R).

Revealing parthenogenetic reproduction in a praying mantis inhabiting South American grasslands [PDF]
Scientific ReportsMantids are charismatic insects due to their appearance and behaviors, but knowledge about them, in particular at the Neotropics, is scarce. Brunneria subaptera (Coptopterygidae) is the most abundant praying mantis species in Uruguay, inhabiting one of ...

Wolbachia-mediated parthenogenesis induction in the aphid hyperparasitoid Alloxysta brevis (Hymenoptera: Figitidae: Charipinae) [PDF]
Applied and Environmental MicrobiologyThelytokous parthenogenesis (thelytoky), in which females can produce female offspring without mating, can be caused by parthenogenesis-inducing endosymbiotic bacteria in the genus Wolbachia.

Identifying and Engineering Genes for Parthenogenesis in Plants
Frontiers 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.

Molecular evidence for the first records of facultative parthenogenesis in elapid snakes [PDF]
Royal Society Open Science, 2018 Parthenogenesis is a form of asexual reproduction by which embryos develop from unfertilized eggs. Parthenogenesis occurs in reptiles; however, it is not yet known to occur in the widespread elapid snakes (Elapidae), which include well-known taxa such as

A key role for sex chromosomes in the regulation of parthenogenesis in the brown alga Ectocarpus.
PLoS Genetics, 2019 Although evolutionary transitions from sexual to asexual reproduction are frequent in eukaryotes, the genetic bases of these shifts remain largely elusive.

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