Research highlights for 2020: an illustration of our main research results

Research Highlights
The research highlights presented here illustrate the significant results achieved by the GABI unit each year and published in international scientific peer review journals.

From the cow to poplar tree, from bees to wheat, how does genomic selection work?

For 10 years, in dairy cattle, "classical" selection has been put aside for genomic selection. This evolution has allowed more rapid progress and a...

Light microscope observation of G. mellonella larvae infected with B. cereus associated with Cry1C toxin 16 hours after force-feeding. Cross–sections (16 µm) (cresyl violet staining and ethanol and xylene dehydration) with focus on the intestine (midgut). The bacteria appear colored as dark or brighter violet. Different magnifications are shown: (a) 4×; (b)10×; (c) 20×, and (d) 40×. (lum: intestinal lumen; bac: bacteria; gEpi: Gut Epithelium; pm: Peritrophic matrix
