Effects of hybridization and evolutionary constraints on secondary metabolites: the genetic architecture of phenylpropanoids in european Populus species

Caseys, Celine ; Stritt, Christoph ; Glauser, Gaetan ; Blanchard, Thierry ; Lexer, Christian

In: PLoS ONE, 2015, vol. 10, no. 5, p. e0128200

The mechanisms responsible for the origin, maintenance and evolution of plant secondary metabolite diversity remain largely unknown. Decades of phenotypic studies suggest hybridization as a key player in generating chemical diversity in plants. Knowledge of the genetic architecture and selective constraints of phytochemical traits is key to understanding the effects of hybridization on plant...

Integrating the ‘genomic mosaic’ view of species into studies of biotic interactions: a comment on Bernhardsson et al. (2013)

Lexer, Christian ; Caseys, Celine ; Stritt, Christoph ; Whitham, Thomas G.

In: Ecology Letters, 2013, vol. 16, no. 12, p. 1515–e7

The co-occurrence of geographical structure in herbivore communities, metabolomes and defence genes in forest trees has been analysed in the context of ‘geographical mosaics’ of coevolution. A deeper understanding of these important issues will require full integration of a ‘genomic mosaic’ view of species into community ecology.
