GenTORE : GENomic management Tools to Optimize Resilience and Efficiency.

The objective of GenTORE is to develop innovative tools for genomic selection and management in order to optimize the resilience and efficacy of cattle in different environments. These tools, including genetic and non-genetic variables, will be applied throughout the all chains of bovine production systems (dairy, beef and mixed). They will increase the economic, environmental and social viability of European production chains of dairy and beaf cattle.

Mapping of domestic animal genomes made in France

Genome mapping of an economically important species means establishing the role of the different elements of the genome. This functional mapping will then provide a better understanding of the relationship of genes and phentoypes (1). INRAE scientists launched the French pilot project FR-AgENCODE in order to enrich genome mapping of four livestock species (cow, chicken, goat and pig). The results of this work, published on December 30, 2019 in BMC Biology, improve knowledge on the functionning of genomes of these species, contributing to the internationally fixed objectives of FAANG (« Functional Annotation of Animal Genomes ») (2).

A new research highlight: "Genetic determinism for cheese-making ability of milk."

Prediction equations for cheese-making abilities using Middle-Infrared spectra of milk were developed and applied to several million spectra in the Monbeliard bovine breed. A genetic analysis shows that coagulation parameters and yield are heritable. An association analysis on the whole genome sequence level identified 59 QTL and a network of 736 co-regulated genes.

RumimiR : a database including all bovine, caprine and ovine microRNA

The massive use of high-throughput sequencing techniqus has generated a large quantity of data. Many publications have described several hundreds of microRNA sequences. We created a new database, RumimiR, containing a detailed description of microRNA in bovines, caprines and ovines.

Impact of genomic selection on genetic diversity in dairy cattle

The arrival of genomic selection in the important dairy cattle breeds has considerably modified selection programs but its impact on genetic diversity was still unknown. This study presents an assessment of the evolution of genetic diversity before and after genomic selection established in the Montbeliard, Normandy and Holstein breeds.

a Web application for new multidisiciplinary partnerships

Multi-omics data provide the ideal occasion for the study of molecular variability and the interaction between different levels of biological complexity. However, their integration, analysis and interpretation may be an important multi-disciplinary challenge. At the same time, the direct creation of web interfaces using the open-source R programming language is now possible, providing an interactive and user-friendly means of communicating data and analysis results.

Genetic diversity of French rainbow trout lines

The genetic diversity of both commercial and experimental French rainbow trout populations was studied using molecular information. Four commercial lines and two experimental lines were genotyped using the AxionTM Trout Genotyping array (using 38000 SNP). The results show a moderate differentiation amongst the lines.
