Local adaptation resulting from selection pressure acts on heritable characters and is a major force shaping the phenotypic diversity of natural populations. Currently, numerous questions exist surrounding the impact of selection on the evolution of genes involved in the structure of adaptive traits, ...

The newly identified APOA5 is a crucial determinant of triglyceride levels and therefore the study of the factors regulating its gene expression is of significant importance. The first part of our studies aims at determining the rôle of APOA5 in inflam...
Napus genotype and the structure of F& hybrids. The effet of the hybrid structure was considerable : at the meiosis of AAC triploid hybnrids, resulting from crosses between B. Napus and B. Rapa, recombination rates were from 1. 8 to 3. 4 fold higher than in AACC tetrploid hybrids, ...
The observed changes in an alcoholic solution have been proven to be the result of elimination followed by photochemical reduction. Similar conclusions have been reached in the case of quinone dibromides.J. Y. SavoieP. Brassardcanadian journal of chemistry...
Finally, polarisation mode dispersion and vectorial modulational instability in the microstructured fibre are studied.Lavender, PaulNotes Bibliogr
