Parthenogenesis-inducing Wolbachia bacteria are reproductive parasites that cause infected female wasps to produce daughters without mating. This manipulation of the host's reproduction enhances the transmission of Wolbachia to future generations because the bacteria are passed on vertically only from mothers to daughters.

The centrosome and parthenogenesis
1999Publisher Summary This chapter discusses the functional description of the centrosome as well as two main aspects of centrosome reproduction and the parthenogenetic activity of the centrosome: (1) the molecular mechanisms underlying centrosome biogenesis itself and (2) the coordination between the nuclear cycle and the centrosome cycle.

Parthenogenesis in Schistosomatidae
Parasitology Today, 1995Among which species, in what situations and how, does parthenogenesis occur in the biology of reproduction of schistosomes? Here, José Jourdane, Daniéle Imbert-Establet and Louis Albert Tchuem Tchuenté review the literature on parthenogenesis in schistosomes, and debate the evolutionary aspects of this type of reproduction.

Centrosomes and parthenogenesis
2001Publisher Summary This chapter describes the parthenogenetic assay and reviews the results concerning the capacity of centrosomes isolated from different cell types in different species to induce frog egg cleavage. The chapter discusses the potential of current in vitro systems to identify important molecular events of the pathway and also ...

Abstract The dominant mode of reproduction in eucaryotes is sexual. This has been described as a paradox given that sex is much more costly than reproducing asexually, such as by parthenogenesis. In the Crustacea, parthenogenesis is commonly found in the Ostracoda and Branchiopoda (Artemia and Cladocera), and studies of these species ...

In vitro treatment of mouse eggs with hyaluronidase can activate them to develop parthenogenetically as well as denuding them of cumulus cells1–4. Activation and subsequent behaviour of the eggs depend on certain defined conditions. Szollosi5 observed morphological changes in unfertilized mouse eggs in vivo after approximately 14 h in the oviduct ...

Parthenogenesis and developmental constraints
Evolution & Development, 2019AbstractThe absence of a paternal contribution in an unfertilized ovum presents two developmental constraints against the evolution of parthenogenesis. We discuss the constraint caused by the absence of a centrosome and the one caused by the missing set of chromosomes and how they have been broken in specific taxa.

Parthenogenesis in Komodo dragons
Nature, 2006Parthenogenesis, the production of offspring without fertilization by a male, is rare in vertebrate species, which usually reproduce after fusion of male and female gametes. Here we use genetic fingerprinting to identify parthenogenetic offspring produced by two female Komodo dragons (Varanus komodoensis) that had been kept at separate institutions and
