Article A continuum of genetic divergence from sympatric host races to species in the pea aphid complex   Peccoud, Jean ; Ollivier, Anthony ; Plantegenest, Manuel ; Simon, Jean-Christophe
Proceedings of the National Academy of Sciences of the United States of America, 2009 , Volume 106 , n° 18 , 7495-7500 p.     [ ISSN : 0027-8424 ]
Résumé :
Sympatric populations of insects adapted to different host plants, i.e., host races, are good models to investigate how natural selection can promote speciation in the face of ongoing gene flow. However, host races are documented in very few model systems and their gradual evolution into good...

Article Early progress in aphid genomics and consequences for plant-aphid interactions studies   Tagu, Denis ; Klingler, J.P. ; Moya, Andrès ; Simon, Jean-Christophe
Molecular Plant Microbe Interactions, 2008 , Volume 21 , n° 6 , 701-708 p.   [ ISSN : 0894-0282 ]
Résumé :
Aphids occupy a niche comprising two conceptual realms: a micron-scale feeding site beneath the plant surface, in which a syringe-like appendage mediates chemical exchange with a specific plant cell type and the larger realm of a metazoan with sensory organs, a nervous system, and behavior, all...

Article Host range expansion of an introduced insect pest through multiple colonizations of specialized clones   Peccoud, Jean ; Figueroa, Christian C. ; Silva, A.X. ; Ramirez, Claudio C. ; Mieuzet, Lucie ; Bonhomme, Joël ; Stoeckel, Solenn ; Plantegenest, Manuel ; Simon, Jean-Christophe
Molecular Ecology, 2008 , Volume 17 , n° 21 , 4608-4618 p.     [ ISSN : 0962-1083 ]
Résumé :
Asexuality confers demographic advantages to invasive taxa, but generally limits adaptive potential for colonizing of new habitats. Therefore, pre-existing adaptations and habitat tolerance are essential in the success of asexual invaders. We investigated these key factors of invasiveness by...

Article Sex versus parthenogenesis: A transcriptomic approach of photoperiod response in the model aphid Acyrthosiphon pisum (Hemiptera: Aphididae)   Cortes, Teresa ; Tagu, Denis ; Simon, Jean-Christophe ; Moya, Andrès ; Martinez-Torres, David
Gene, 2008 , Volume 408 , n° 1-2 , 146-156 p.   [ ISSN : 0378-1119 ]
Résumé :
Most aphids develop a cyclic parthenogenesis life-cycle. After several generations of viviparous parthenogenetic females, it follows a single annual generation of sexual individuals, usually in autumn, that mate and lay the sexual eggs. Shortening of photoperiod at the end of the summer is a key...
