The metabolic secrets of horse-athlete endurance

The intestinal microbiota and energy centers of the blood cells of horses communicate to ensure an unfailing endurance! A dialogue based on fatty acid production allows the animal to adapt its metabolism to delay fatigue, hypoglycemia and reduce inflammation. These are the conclusions of a study led by INRAE in partnership with the National Veterinary School at Alfort and the University of Evry. These results, published in Frontiers in Molecular Biosciences lead the way to custom-made diets for endurance race horses, to guarantee their performances, welfare and health.

Resilience of the intestinal microbiota in stressed equine athletes

Elite horse athletes that live in individual boxes undergo long-term physical and mental stress that compromises the welfare of these animals altering their intestinal microbiota. In a studied published in Scientific Reports, scientists from INRAE laboratories including Animal Genetics and Integrative Biology - GABI evaluated whether a temporary period at pasture with other animals could improve animal welfare and, in return, favorably affect the intestinal microbiota composition.

Analysis of the genetic determinism of the mineral concentration of cow's milk

The composition in minerals of cow's milk plays an important role in its nutritional value and its cheese-making abilities. By combining high-throughput phenotyping with middle infrared spectrometry (MIR), large-scale genotyping, association and annotation analyses, 50 regions of the genome were detected that affect the main mineral concentrations, identifying the genes implicated and candidate genetic variants (usually involved in regulation). The genes SLC37A1 and ANKH explain the most significant QTL.

The creation of INRAE's first Assoicated Partnership Laboratory: dedicated to innovation with Excilone

Due to the major challenges facing our societies, expectations of research are growing. To respond through real innovation to the industry's and society's problems, the intensifiction of interactions between public resarch with companies is a key. By placing innovation as one of the pilars in its strategy for the next 10 years [1], at the beginning of 2021, INRAE has launched a new type of partnership with social-economic actors: the Associated Partnership Laboratory. Thus, on the basis of a common roadmap for 5 years, the partnership will allow INRAE and Excilone to share their material and human resources around a co-conceived research and technological programme in the field of microgenomics. This is a new type of partnership for INRAE that is both flexible and adaptable whose objective is to accelerate the development of new innovations.

Mystery of four-horned goats and sheep finally solved

In meadows, we can sometimes see sheep and goats with four horns instead of two. Some breeds, like the Manx Loaghtan from the Isle of Man, are famous for their unusual headgear. A team of researchers from INRAE, the University of Geneva, the Polytechnic School of Lausanne, the French National Union of Cooperatives for Animal Insemination (ALLICE), as well as from several museums and breeding associations, has been investigating the genetic causes of this curious morphological phenomenon. Published in the journal Molecular Biology and Evolution on 16 February 2021, their results show that all the polycerate animals studied carried a mutation in the same gene: HOXD1.

An environmentally relevant mixture PCBs and PBDEs disrupts mitochondrial function, lipid metabolism and neurotransmission in the brain of exposed zebrafish and their unexposed F2 offspring

Polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDE) are persistant organic pollutants present in aquatic environments despite their either total or partial removal from the market. Chronic exposition of zebrafish, a fish model, to a mixture of PCB and PBDE that is representative of European environmental situations, affects the energy metabolism, growth and reproduction in the exposed zebrafish (F0) as well as the behavior of their non-exposed offspring (F1-F4) (Horri et al., 2018 ; Alfonso et al., 2019).

The project « A thousand Gallus genomes» : sharing sequene data for their improved use.

Whole genome sequencing has changed many fields in genetics: selection, biodiversity, understanding the genotype-phenotype relationship. The idea of a "1000 Genomes" project, tested in cattle, consists of sharing sequence data obtained by different partners to facilitate the extraction of information that answers the different research questions. Here we present how this will be done for the chicken on both national and international levels.

A phylogenomic approach rebuild the evolUne approche phylogénomique permet de reconstruire l’histoire évolutive du genre Gallus (et d’identifier des hybrides)

The evolutive history of the Gallus genus, including the chicken, has been explored in many studies that have led to incompatible phylogenetic trees. The genus is made up of 4 wild fowl species: the red junglefowl (Gallus gallus, southeast Asia), the grey junglfowl (Gallus sonneratti, India), the Lafayette's junglefowl (Gallus lafayetti, Sri Lanka) and the green junglfowl (Gallus varius, Indonesia). Previous studies suggest that the ancestral branch concerns either the red junglfowl (A scenario) or the green junglfowl (B scenario). They have limits however: often only one bird per species, few genes, etc.

Production of the bovine rumen microbiota gene catalogue: a surprising diversity despite a high specialization in plant degradation

A catalogue of procaryote genes present in the bovine rumen has been compiled. It will help decipher the potential roles of the microbiota as a whole, in particular its ability to degrade structural carbohydrates in forages.

AQUAEXCEL3.0 : a project for the development of European aquaculture

Where do your sea products come from? In Europe, 75% of these products are imported. It therefore seems important to guarantee a sustainable growth for aquaculture in Europe. Such is the mission of the H2020 AQUAEXCEL project, which began in 2011. Today it evolves to a third edition: AQUAEXCEL3.0.

Sea bass, a fish whose sex depends on temperature .... one way and the other

On the contrary to mammals and birds in which sex is determined at conception by sex chromosomes (X and Y being the most well-known), it is frequent in fish and reptiles that sex be determined at least in part by water temperature at a key developmental stage. This is true in sea bass, but, in a surprising way, the same temperature can produce males or females depending on the moment of development where they are applied. This is what a study by the Animal Genetics and Integrative Biology Unit (GABI, INRAE, AgroParisTech, Université Paris-Saclay) and the MARine Biodiversity, Exploitation and Conservation (MARBEC, IRD, Ifremer, Université de Montpellier, CNRS), found and which was published on 4 November, 2020 in the journal Ecology and Evolution.

Spontaneous masculinisation in female genetic trout: a genetic origin n part

During evolution, fish have developed a remarkable diversity of sex phenotypic control mechanisms, associating heterogametic systems such as XX/XY as in mammals or ZZ/ZW as in birds to polygenic systems or those regulated by the environment. In the rainbow trout (Oncorhynchus mykiss), sex is dictated by a simple chromosome system (XX/XY) and the major sex determinant is known (sdY gene). This genetic determinism is used to produce completely female populations (XX), which are more interesting that bisexual populations. However, male individuals are regularly observed in these XX populations.
