Séquencer des échantillons anciens stockés en cryobanques pour comprendre comment le génome des animaux domestiques a évolué avec la sélection
Simon Boitard, Laurence Liaubet, Cyriel Paris, Katia Fève, Patrice Dehais, et al. Whole-genome sequencing of cryopreserved resources from French Large White pigs at two distinct sampling times reveals strong signatures of convergent and divergent selection between the dam and sire lines. Genetics Selection Evolution, 2023, 55, pp.13. 10.1186/s12711-023-00789-z hal-04016249
L’étude détaillée de chaque région a également révélé que les signatures de sélection les plus marquées étaient souvent associées à des gènes dont la fonction biologique est particulièrement pertinente pour les caractères sélectionnés. Dans un de ces gènes, IGF2, on observe la sélection d’une mutation génétique affectant la croissance musculaire bien connue dans plusieurs races de porc dont le Large White.
New methods for genotyping honeybee colonies
The honey bee is an eusocial species organized in colonies of several thousand individuals. From a genetic point of view, the founding queen of a colony mates beforehand with several males to constitute a pool of spermatozoa which will be used throughout her life to produce the individuals of the colony. Most of the colony is made up of diploid workers resulting from fertilizations and occasionally of a few haploid males, resulting from an unfertilized gamete of the queen and whose role is only reproductive. In beekeeping, traits of interest for selection are mainly measured at the colony level, whereas selection is mainly done at the queen level. It is therefore essential to develop methods that allow to genotype a colony at a lower cost.
