“…Abstract The prevalent mode of reproduction among ants is arrhenotokous parthenogenesis where unfertilized eggs give rise to haploid males and fertilized eggs develop into diploid females. …”

Going solo: discovery of the first parthenogenetic gordiid (Nematomorpha: Gordiida). by Ben Hanelt, Matthew G Bolek, Andreas Schmidt-Rhaesa

“…To determine the mechanism of this mating strategy, we ruled out the involvement of reproduction manipulating endosymbionts by use of next generation sequencing data, thus suggesting that parthenogenesis is determined genetically and may have evolved as a means to assure reproduction. …”

Origin and genetic diversity of diploid parthenogenetic Artemia in Eurasia. by Marta Maccari, Francisco Amat, Africa Gómez

“…There are three mechanisms that can be responsible for the generation of genetic diversity of parthenogenetic lineages: contagious parthenogenesis, repeated hybridization and microorganism infections (e.g. …”

Evidence for widespread cryptic sexual generations in apparently purely asexual Andricus gallwasps. by Stone, G, Atkinson, R, Rokas, A, Aldrey, J, Melika, G, Acs, Z, Csóka, G, Hayward, A, Bailey, R, Buckee, C, Mcvean, G

“…Oak gallwasps (Hymenoptera, Cynipidae, Cynipini) are one of seven major animal taxa that commonly reproduce by cyclical parthenogenesis (CP). A major question in research on CP taxa is the frequency with which lineages lose their sexual generations, and diversify as purely asexual radiations. …”

The map-1 gene family in root-knot nematodes, Meloidogyne spp.: a set of taxonomically restricted genes specific to clonal species. by Iva Tomalova, Cathy Iachia, Karine Mulet, Philippe Castagnone-Sereno

“…A phylogenetic analysis of the distribution of map-1 genes in RKNs further showed that these genes are specifically present in species that reproduce by mitotic parthenogenesis, with the exception of M. floridensis, and could not be detected in RKNs reproducing by either meiotic parthenogenesis or amphimixis. …”

The Rise of Apomixis in Natural Plant Populations by Diego Hojsgaard, Elvira Hörandl

“…Many studies suggest that hybridization, either on diploid or polyploid cytotypes, is a major trigger for the formation of unreduced female gametophytes, which represents the first step toward apomixis, and must be combined to parthenogenesis, the development of an unfertilized egg cell. …”

Evolutionary origin and phylogeography of the diploid obligate parthenogen Artemia parthenogenetica (Branchiopoda: Anostraca). by Joaquín Muñoz, Africa Gómez, Andy J Green, Jordi Figuerola, Francisco Amat, Ciro Rico

“…Phylogenetic and phylogeographic analyses indicated a multiple and recent evolutionary origin of diploid A. parthenogenetica, and strongly suggested that the geographic origin of parthenogenesis in Artemia was in Central Asia. Our results indicate that the maternal sexual ancestors of diploid A. parthenogenetica were an undescribed species from Kazakhstan and A. urmiana.We found evidence for multiple origin of parthenogenesis in Central Asia. …”

Alteration of sexual reproduction and genetic diversity in the kelp species Laminaria digitata at the southern limit of its range. by Luz Valeria Oppliger, Peter von Dassow, Sarah Bouchemousse, Marine Robuchon, Myriam Valero, Juan A Correa, Stéphane Mauger, Christophe Destombe

“…Laboratory observations have shown that brown algae exhibit a high propensity for parthenogenesis by various mechanisms. The kelp Laminaria digitata is an important component of the ecosystem in Northern European rocky intertidal habitats. …”

Apomictic and sexual germline development differ with respect to cell cycle, transcriptional, hormonal and epigenetic regulation. by Anja Schmidt, Marc W Schmid, Ulrich C Klostermeier, Weihong Qi, Daniela Guthörl, Christian Sailer, Manuel Waller, Philip Rosenstiel, Ueli Grossniklaus

“…We used the apomict Boechera gunnisoniana, a close relative of Arabidopsis thaliana, to investigate the transcriptional basis underlying apomeiosis and parthenogenesis. Here, we present the first comprehensive reference transcriptome for reproductive development in an apomict. …”

The role of declining ataxia-telangiectasia-mutated (ATM) function in oocyte aging by Suzuki, R, Tan, X, Szymanska, KJ, Kubikova, N, Perez, CA, Wells, D, Oktay, KH

“…ATM knockdown significantly lowered or blocked the progression of meiosis in vitro, as well as retarding and reducing embryo cleavage after parthenogenesis. After ATM knockdown, all embryos were of poor quality, and none reached the blastocyst stage. …”

Determination of the Developmental Origin of Seeds Containing Endosperm Using Flow Cytometric Analysis by Christian Sailer, Anja Schmidt, Ueli Grossniklaus

“…Moreover, sexual and apomictic pathways can occur in the same plant and sometimes they cross over, producing polyhaploid offspring (n+0; resulting from meiosis and parthenogenesis) or BIII hybrids (2n+n; resulting from apomeiosis and fertilization) (Rutishauser, 1947). …”

Viewpoints on apornictic and sexual reproduction in angiosperms by Sven Asker

“…Each of these "elements of apomixis" occurs in sexual plants, which may even display functional diploid parthenogenesis. Thus, apomixis, like vegetative reproduction, is part of the reproductive behaviour of sexual plants, becoming important when sexual reproduction is impaired. …”
