SpletAbstract. Wolbachia are widespread bacteria which infect a number of species of insects and other arthropods. They manipulate the reproduction of their hosts at their own … Splet04. jun. 2024 · Kishani Farahani et al. (2024) showed differences in learning ability and memory retention between Wolbachia-infected and -uninfected T. brassicae and suggested that it may be due to negative side effects of Wolbachia infection. However, the possibility that the learning impairment between infected and uninfected strains may be due to …

SpletAmong eukaryotes, sexual reproduction is by far the most predominant mode of reproduction. However, some systems maintaining sexuality appear particularly labile and raise intriguing questions on the evolutionary routes to asexuality. Thelytokous parthenogenesis is a form of spontaneous loss of sexuality leading to strong distortion … Splet26. mar. 2014 · We demonstrate that thelytoky evolved from ancestral arrhenotoky through the horizontal transmission and the fixation of the parthenogenesis‐inducing Wolbachia . …

Splet31. maj 2012 · We tested whether or not endosymbiotic bacteria Wolbachia are associated with thelytoky in eight species of oribatid mites (as it is for most thelytokous parasitic Hymenoptera studied so far) by using a polymerase chain reaction assay.
Splet20. okt. 2011 · Wolbachia infection leads to an increase in the mitotic activity of germline stem cells (GSCs), as well as a decrease in programmed cell death in the germarium. Our results suggest that up-regulation of GSC division is mediated by a tropism of Wolbachia for the GSC niche, the cellular microenvironment that supports GSCs. SpletTo address thelytoky; this issue, we screened all known thelytokous social hymenopteran species Wolbachia; using a PCR assay. None was infected, and therefore we conclude that worker worker reproduction. thelytoky evolves independently of …

Splet03. sep. 2002 · Wolbachia bacteria infect ≈ 20% of all insect species, and cause a range of alterations to host reproduction, including imposition of thelytoky.

For instance, it can cause cytoplasmic incompatibility ( James and Ballard 2000 ), feminization of genetic males ( Rousset et al. 1992 , Bouchon et al. 1998 ), and male killing ( Hurst et al. 1999a , b ), or it can be required for oocyte ... incentivise toowoombaSplet22. feb. 2015 · Background Thelytoky, the parthenogenetic development of females, has independently evolved in several insect orders yet the study of its mechanisms has so far mostly focussed on haplodiploid Hymenoptera, while alternative mechanisms of thelytoky such as polyploidy are far less understood. In haplodiploid insects, thelytoky can be … incentivise ownerSplet18. mar. 2016 · In the Wolbachia-mediated vector control, the risk appears in the form of possible host-shifts of Wolbachia to nontarget organisms. However, it is estimated that about 40-66% of all arthropod species are infected with Wolbachia (1, 2); hence, it may be less impressive to emphasize that the plausible host-shift mediated through the target ... incentivise meansSplet13. okt. 2024 · Insects have close symbiotic relationships with several microbes, which extends the limited metabolic networks of most insects.
