UMR1313 GABI - Animal Genetics and Integrative Biology

Joint INRAE AgroParisTech Unit

Understanding and exploiting the genetic variability of animals.

The scientific orientations of GABI aim to understand and exploit the genetic variability of animals to analyze the construction of phenotypes, interactions with microbial ecosystems and the environment at large, in a context of agroecological transition.

Caesarean birth: sex-specific effects on the microbiota

The effects of caesarean delivery on the newborn microbiota appear to vary according to sex. A research team coordinated by INRAE demonstrates this in a mouse model, showing increased susceptibility to colonic inflammation and a compromised gut barrier in males. These findings were published in Gut Microbes.

Extending the laying period of hens has become a key challenge for more sustainable egg production. A study based on stochastic simulations explores how genomic selection and the reduction of the generation interval can accelerate progress. The results show significant genetic gains, particularly toward the end of the hens’ productive lives.

Myostatin is a protein that acts as a natural brake on muscle growth. It is encoded by a gene called MSTN. In this study, researchers developed a specific functional test to check whether certain variants of this gene disrupt splicing.
