Contribution of Epigenetic Mechanisms in the Regulation of Environmentally-Induced Polyphenism in Insects

Autor: Gautier Richard, Julie Jaquiéry, Gaël Le Trionnaire

Publikováno v: Insects, Vol 12, Iss 7, p 649 (2021)

Many insect species display a remarkable ability to produce discrete phenotypes in response to changes in environmental conditions. Such phenotypic plasticity is referred to as polyphenism. Seasonal, dispersal and caste polyphenisms correspond to the

Dosage compensation and sex-specific epigenetic landscape of the X chromosome in the pea aphid

Autor: Gautier Richard, Fabrice Legeai, Nathalie Prunier-Leterme, Anthony Bretaudeau, Denis Tagu, Julie Jaquiéry, Gaël Le Trionnaire

Publikováno v: Epigenetics & Chromatin, Vol 10, Iss 1, Pp 1-17 (2017)

Abstract Background Heterogametic species display a differential number of sex chromosomes resulting in imbalanced transcription levels for these chromosomes between males and females. To correct this disequilibrium, dosage compensation mechanisms in

Differential Expression of Candidate Salivary Effector Genes in Pea Aphid Biotypes With Distinct Host Plant Specificity

Autor: Hélène Boulain, Fabrice Legeai, Julie Jaquiéry, Endrick Guy, Stéphanie Morlière, Jean-Christophe Simon, Akiko Sugio

Publikováno v: Frontiers in Plant Science, Vol 10 (2019)

Effector proteins play crucial roles in determining the outcome of various plant-parasite interactions. Aphids inject salivary effector proteins into plants to facilitate phloem feeding, but some proteins might trigger defense responses in certain pl

Evolutionary consequences of loss of sexual reproduction on male-related traits in parthenogenetic lineages of the pea aphid

Autor: Hélène Defendini, Maud Rimbault, Frédérique Mahéo, Romuald Cloteau, Gaëtan Denis, Lucie Mieuzet, Yannick Outreman, Jean‐Christophe Simon, Julie Jaquiéry

Molecular Ecology, 2023, ⟨10.1111/mec.16961⟩

International audience; Transition from sexual reproduction to parthenogenesis constitutes a major life-history change with deep evolutionary consequences for sex-related traits, which are expected to decay. The pea aphid Acyrthosiphon pisum shows in

Masculinization of the X-chromosome in aphid soma and gonads

Autor: Stéphanie Robin, N. Prunier-Leterme, Jean Peccoud, Gautier Richard, Julie Jaquiéry, Fabrice Legeai, Hélène Boulain, G. Le Trionnaire, Sylvie Tanguy, J-C Simon

Publikováno v: Peer Community Journal
Peer Community Journal, 2022, 2, pp.e53. ⟨10.24072/pcjournal.166⟩

Males and females share essentially the same genome but differ in their optimal values for many phenotypic traits, which can result in intra-locus conflict between the sexes. Aphids display XX/X0 sex chromosomes and combine unusual X chromosome inher

Genetic control of contagious asexuality in the pea aphid.

Autor: Julie Jaquiéry, Solenn Stoeckel, Chloé Larose, Pierre Nouhaud, Claude Rispe, Lucie Mieuzet, Joël Bonhomme, Frédérique Mahéo, Fabrice Legeai, Jean-Pierre Gauthier, Nathalie Prunier-Leterme, Denis Tagu, Jean-Christophe Simon

Publikováno v: PLoS Genetics, Vol 10, Iss 12, p e1004838 (2014)

Although evolutionary transitions from sexual to asexual reproduction are frequent in eukaryotes, the genetic bases of such shifts toward asexuality remain largely unknown. We addressed this issue in an aphid species where both sexual and obligate as

Masculinization of the x chromosome in the pea aphid.

Publikováno v: PLoS Genetics, Vol 9, Iss 8, p e1003690 (2013)

Evolutionary theory predicts that sexually antagonistic mutations accumulate differentially on the X chromosome and autosomes in species with an XY sex-determination system, with effects (masculinization or feminization of the X) depending on the dom
