Summary: This study reveals the origin and reproduction mode of various asexual lineages of the brine shrimp Artemia parthenogenetica, showcasing the importance of considering scenarios of asexuality by transmission in understanding sex-asex transitions.

Summary: Obligate parthenogenesis has evolved multiple times in reptiles through interspecific hybridization, resulting in the formation of diploid and triploid lineages. This study shows that oocytes in several widespread parthenogenetic complexes of geckos undergo meiosis and produce unreduced eggs through premeiotic endoreplication, allowing for the emergence of fertile polyploid lineages within parthenogenetic complexes.

Summary: Research on the brine shrimp Artemia parthenogenetica reveals the presence of cryptic sex and hybridization in asexual lineages, leading to genetic differences between parents and offspring. While these differences are not easily observable in field-sampled asexuals, they suggest a need to reconsider the assumption of strictly clonal reproduction in asexual species and to consider rare sexual reproduction and consequences of nonclonal asexuality in models for the maintenance of sex and the persistence of asexual lineages.

Summary: In this study, evidence for cryptic sex was found in two populations of Timema stick insects, which could help explain the success of parthenogenesis in this genus and raises questions about the persistence of old parthenogens in nature.

Summary: The unusual occurrence and developmental diversity of asexual eukaryotes are still a puzzle, with lack of complementation of molecular changes in the sexual reproductive program being a main cause for their rarity. This lack of complementation can explain the developmental diversity and lability of developmental patterns in some asexuals.

Summary: The study found that only a few genes are consistently associated with asexual evolution, suggesting that extensive restructuring of the meiotic machinery may not be necessary. Sex-biased genes in Eurasian Artemia have high rates of expression divergence, but do not show unusual evolutionary patterns after the loss of sexuality.

Summary: This study used capture sequencing to estimate phylogenetic relationships and gene flow among Darevskia species, and found evidence for widespread hybridization and gene flow. The results suggest that the generation of parthenogenetic hybrids in Darevskia is a rare outcome of hybridization events within the genus, but a typical outcome when specific species pairs hybridize.

Summary: The scarcity of asexual reproduction in vertebrates comes with an inherent cost. Asexual species of Aspidoscelis lizards exhibit reduced endurance capacity, mitochondrial respiration, and phenotypic variability compared to parental sexual species, indicating potential mitonuclear incompatibility.

Summary: Obligate parthenogenesis (OP) is believed to evolve by disrupting meiosis and recombination, but our study on Daphnia pulex shows that males capable of reductional meiosis have only slightly reduced recombination rates compared to cyclic parthenogenetic (CP) individuals. This sex-limited effect contradicts the assumption that an essential gene for meiosis or recombination is disrupted. Our findings suggest that OP may have evolved through a reuse and extension of existing parthenogenesis pathways in CP, possibly involving mutations in genes regulating oogenesis. Understanding the mechanisms of asexuality is crucial for identifying the genes and traits involved.

Summary: This review article summarizes the current knowledge on true parthenogenesis, specifically thelytoky, in Fulgoromorpha (planthoppers) and Cicadomorpha (leafhoppers), two major suborders of the diverse order Hemiptera. The article discusses various aspects such as distribution patterns, ecology, mating behavior, acoustic communication, and the cytogenetic and genetic diversity of parthenoforms. The authors also highlight instances of skewed sex ratios in natural populations and discuss the potential influence of endosymbiotic bacteria on reproductive strategies.

Summary: In facultatively parthenogenetic populations, the reproductive origin of females has an impact on their development, performance, and mating behavior. Parthenogenetically produced females tend to be smaller and more prone to deformities, receive fewer mating attempts, and avoid mating more often compared to sexually produced females. However, mating does not provide a net reproductive benefit for parthenogenetically produced females, suggesting physiological constraints that limit the fitness returns of sexual reproduction. These findings highlight the importance of female reproductive origin in determining the advantages of mating in this species.

Summary: Monomorium is a species-rich ant genus with taxonomic issues, and the East Asian species M. triviale reproduces through obligate thelytokous parthenogenesis and strict reproductive division of labor. The mitogenome of M. triviale, which was sequenced using next-generation methods, is circular in shape and consists of 13 protein-coding genes, two ribosomal RNA genes, 22 transfer RNAs, and a non-coding region. Gene order rearrangements were detected, likely unique to the Monomorium genus, making the M. triviale mitogenome a valuable genomic resource for phylogenetic and taxonomic studies on parthenogenetic ant species.

Summary: The ant species Monomorium triviale exhibits obligatory thelytokous parthenogenesis, where queens can produce workers and new queens without mating. Genetic analysis showed identical genotypes between mothers and daughters, indicating extremely low probability of sexual reproduction. Additionally, no bacteria known to induce thelytokous parthenogenesis in Hymenoptera were detected.

Summary: Over the past two decades, there has been a significant increase in documentation of facultative parthenogenesis (FP) in vertebrates. This reproductive mode has been observed in birds, lizards, snakes, and elasmobranch fishes. The discovery of FP in a crocodilian species, the American crocodile, suggests a common evolutionary origin of FP across reptiles, crocodilians, and birds.

Summary: This study examines the genetic mechanisms of sex loss in the pea aphid, finding that an X-linked region is associated with the variation in reproductive mode. The region is highly divergent between cyclic parthenogenetic and obligate parthenogenetic populations, and a large number of SNPs and short Indels show a high degree of association with the phenotypic trait. The study also suggests gene flow between the populations, with males from obligate parthenogenetic lineages likely transmitting their op allele to new genomic backgrounds.
