Comparative analysis of 163 ant genomes reveals recurrent horizontal gene transfer from bacteria to ants
AbstractBackground. Horizontal gene transfer (HGT) from bacteria can drive phenotypic innovation and adaptation in eukaryotes. Ants are likely carriers of

This week @annazaidmanremy.bsky.social and @jesuxueml.bsky.social were at the EMBL symposium entitled “The cellular mechanics of symbiosis: sensing friend from foe” @events.embl.org. They gave excellent presentations which sparked lively discussions! #EESSymbiosis #SymbioSky
Next, Jesus Uxue Mendez Leyva on a recently acquired bacterial endosymbionts in weevils. Their genomes have lots mobile genomic elements suggesting that they are undergoing a period of genomic instability, and the genes associated with TEs might play a role in the symbiosis #EESSymbiosis
