- Developmental origin and evolution of bacteriocytes in the aphid-Buchnera symbiosisChristian Braendle
Department of Ecology and Evolutionary Biology, Princeton University, Princeton, New Jersey, USA
PLoS Biol 1:E21. 2003..The evolutionary transition to a symbiosis in which bacteria and an aphid cell form a functional unit, similar to the origin of plastids, has apparently involved extensive molecular adaptations on the part of the host cell...

Laboratory for Development and Evolution, University Museum of Zoology, Cambridge CB2 3EJ, UK
Heredity (Edinb) 94:435-42. 2005..Our study presents the first mapping of a gene with known function in aphids, and the results indicate that target gene mapping in aphids is feasible...
- Sex determination: ways to evolve a hermaphroditeChristian Braendle
Institut Jacques Monod, CNRS Universités Paris 6 and 7, Tour 43, 2 place Jussieu, 75251 Paris Cedex 05, France
Curr Biol 16:R468-71. 2006..elegans and C. briggsae, however, produce self-fertile hermaphrodites instead of females. These transitions to hermaphroditism evolved convergently through distinct modifications of germline sex determination mechanisms...
- Wing dimorphism in aphidsC Braendle
Institut Jacques Monod, CNRS, Universités Paris 6 and 7, Tour 43, 2 place Jussieu, 75251 Paris Cedex 05, France
Heredity (Edinb) 97:192-9. 2006..We first provide a description of the dimorphism and an overview of its phylogenetic distribution. We then review what is known about the mechanisms underlying the dimorphism and end by discussing its evolutionary aspects...
- A role for genetic accommodation in evolution?Christian Braendle
Institut Jacques Monod, CNRS, Universités Paris 6 and 7, Paris, France
Bioessays 28:868-73. 2006..We argue that genetic accommodation, including assimilation, is a plausible mechanism in evolution; however, more work is required to test how this mechanism acts and how often it is involved in evolutionary change...
- Genetic variation for an aphid wing polyphenism is genetically linked to a naturally occurring wing polymorphismChristian Braendle
Laboratory for Development and Evolution, Department of Zoology, University Museum of Zoology, Downing Street, Cambridge CB2 3EJ, UK
Proc Biol Sci 272:657-64. 2005..This finding is consistent with the hypothesis that genotype by environment interaction at the api locus explains genetic variation in the environmentally cued wing polyphenism...
- The other side of phenotypic plasticity: a developmental system that generates an invariant phenotype despite environmental variationChristian Braendle
Institut Jacques Monod, CNRS University of Paris 6, Tour 43, 2 place Jussieu, 75251 Paris Cedex 05, France
J Biosci 34:543-51. 2009..Fourth, we discuss the evolutionary significance of environmental sensitivity of this developmental system...
- Bias and evolution of the mutationally accessible phenotypic space in a developmental systemChristian Braendle
Institut Jacques Monod, CNRS Universite Paris Diderot, Paris, France
PLoS Genet 6:e1000877. 2010..This study provides an empirical assessment of developmental bias and the evolution of mutationally accessible phenotypes and supports the notion that such bias may influence the directions of evolutionary change...
- Plasticity and errors of a robust developmental system in different environmentsChristian Braendle

Institut de Biologie Valrose, CNRS, UMR7277, Parc Valrose, Nice Cedex 02, 06108, France
BMC Evol Biol 13:10. 2013..elegans developmental biology and molecular genetics, biologists lack basic data for understanding the abundance and distribution of Caenorhabditis species in natural areas that are unperturbed by human influence...
- Mechanisms and evolution of environmental responses in Caenorhabditis elegansChristian Braendle
Institut Jacques Monod, CNRS Universities of Paris 6 7, Tour 43 2 Place Jussieu, 75251 Paris Cedex 05, France
Curr Top Dev Biol 80:171-207. 2008..Second, we discuss the development of the C. elegans vulva. This example illustrates how development responds to variation in the environment while generating an invariant final phenotype...
