Description

Alejandra Samano and a large student team hunt the gene faults behind classic fruit fly traits in a 2026 study. Structural variants, large DNA rearrangements, form much trait variation but hide from short read sequencing. Long read assemblies for 11 Drosophila melanogaster strains were joined into a pangenome graph with fine maps of those variants.

The team traced 50 classic visible traits and found new candidate faults for 15 of them. A wing vein trait linked to a 1.5 kilobase partial gene duplication, and the century old Curved wing trait linked to a 7.5 kilobase retrotransposon breaking a muscle gene. Harmful visible traits proved rich in structural variants.
