We used polymorphic microsatellite markers to look for recombination during parthenogenetic oogenesis between the X chromosomes of aphids of the tribe Macrosiphini. We examined the X chromosome because it comprises ∼25% of the genome and previous cytological observations of chromosome pairing and nucleolar organizer (NOR) heteromorphism suggest recombination, although the same is not true for autosomes. A total of 564 parthenogenetic females of Myzus clones with three distinct reproductive modes (cyclical parthenogenesis, obligate parthenogenesis and obligate parthenogenesis with male producti

AbstractThis study examines the spatial and seasonal patterning of mitochondrial DNA diversity in French populations of the bird cherry-oat aphid, Rhopalosiphum padi (Linnaeus), on both its primary and secondary hosts. Our results confirm the presence of two major mitochondrial lineages that are generally associated with the breeding system variation (cyclic and obligate parthenogenesis) shown by this species. The strength of this relationship varies regionally, being most evident in the south and west. Cyclically parthenogenetic populations show no significant regional or seasonal genetic div

Previous surveys have shown that most populations of Daphnia pulex in the Great Lakes watershed reproduce by obligate parthenogenesis. Cyclically parthenogenetic populations, in which there is sexual reproduction, are confined to only a few isolated areas. The present study assessed genetic variation within and among 11 cyclically parthenogenetic populations. The results for six polymorphic enzyme loci showed that variation within the populations conformed to that expected for populations with frequent sexual reproduction. Seven of the populations sampled in 1988 were previously sampled in eit

AbstractHeat-shock proteins 90 (hsp90s) are a class of molecules able to stabilize a network of ‘client’ proteins that are involved in several processes. Furthermore, recent studies indicated that mutations in the hsp90-encoding gene induce a wide range of phenotypic abnormalities, which have been interpreted as an increased sensitivity of different developmental pathways to hidden/cryptic mutations. In order to verify the role of hsp90 in aphids, we amplified and sequenced the hsp90 gene in 17 lineages of the peach potato aphid Myzus persicae (Sulzer, 1776) looking for the presence of mutatio

Parthenogenesis represents a distinctive form of asexual reproduction wherein embryos originate from unfertilized eggs. Once considered merely a biological anomaly, it has now been documented across a wide range of taxa, including invertebrates, vertebrates, and plants. Parthenogenesis provides valuable insights into developmental biology, genetics, and evolutionary processes. This review examines its classification, mechanisms, distribution, evolutionary significance, molecular foundations, and emerging roles in biotechnology and conservation. By integrating historical observations with conte

AbstractDifferences in amplified fragment length polymorphisms (AFLP) between isolates and between mono-female lines of facultative automictic Meloidogyne hapla race A and obligate apomictic M. incognita were determined to test the hypothesis that inverted meiosis occurs. DNA of the parthenogenetic nematode lines were extracted from juveniles, which had been propagated for two generations, allowing males in M. hapla lines to be formed and fertilisation to take place. Based on AFLP analysis, the genetic distance between mono-female lines of M. incognita appeared to be almost nil. By contrast, t

Arrhenotoky is the typical mode of reproduction in Hymenoptera. Diploid females develop from fertilized eggs, whereas haploid males originate from unfertilized eggs. However, some taxa of Hymenoptera have evolved thelytoky, in which diploid females originate parthenogenetically from unfertilized diploid eggs. In contrast to some other hymenopteran lineages, like ants and parasitic wasps, thelytoky is generally very rare in bees. Here, we evaluated the frequency of thelytoky in the small carpenter bee Ceratina dallatoreana, which was previously assumed to be thelytokous. By comparing genotypes
