Project description:In social insects, workers perform distinct tasks according to the caste they belong to, and workers from different castes differ in their age (nest workers are usually younger than foragers are). The caste shift thus seems inseparable from age, preventing from deciphering the role of labour division and age in regulating individual physiology and ageing rates. We set up an experimental protocol separating age and caste effects by defining four groups of black garden ant (Lasius niger) workers: young foragers (Y.F), old foragers (O.F), young nest workers (Y.NW) and old nest workers (O.NW). Proteomics highlighted differences between individuals according to their age, whereas metabolomics revealed caste-related differences. Our study highlighted that age and caste influence specifically different aspects of the physiology of ant workers.

Project description:The genetic foundation of chicken tail feather color is not very well studied to date, though that of body feather color is extensively explored. In the present study, we used a synthetic chicken dwarf line (DW), which was originated from the hybrids between a black tail chicken breed, Rhode Island Red (RIR) and a white tail breed, Dwarf Layer (DL), to understand the genetic rules of the white/black tail color. The DW line still contain the individuals with black or white tails, even if the body feather are predominantly red, after more than ten generation of self-crossing and being selected for the body feather color. We firstly performed four crosses using the DW line chickens including black tail male to female, reciprocal crosses between the black and white, and white male to female to elucidate the inheritance pattern of the white/black tail. We found that (i) the white/black tail feather colors are independent of body feather color and (ii) the phenotype are autosomal simple trait and (iii) the white are dominant to the black in the DW lines. Furtherly, we performed a genome-wide association (GWA) analysis to determine the candidate genomic regions underlying the tail feather color by using black tail chickens from the RIR and DW chickens and white individuals from DW lines.
