Unravelling the genetics of fungal fratricide

Unravelling the genetics of fungal fratricide

Press Releases   •   Oct 15, 2018 12:38 BST

Selfish genes are genes that are passed on to the next generation but confer no advantage on the individual as a whole, and may sometimes be harmful. Researchers at Uppsala University have, for the first time, sequenced (or charted) two selfish genes in the fungus Neurospora intermedia that cause fungal spores to kill their siblings.

New knowledge about retrovirus-host coevolution

Press Releases   •   Oct 08, 2018 20:00 BST

Retroviruses have colonised vertebrate hosts for millions of years by inserting their genes into host genomes, enabling their inheritance through generations as endogenous retroviruses (ERVs). Researchers from Uppsala University now provide new knowledge about the long-term associations of retroviruses and their hosts by studying ERV variation and segregation in wild and domestic rabbits.

The origin of a new species of Darwin’s finches

Press Releases   •   Nov 23, 2017 20:35 GMT

Darwin’s finches in the Galápagos archipelago provide an iconic model for the evolution of biodiversity on earth due to natural selection. A team of scientists from Princeton University and Uppsala University now reports that they have observed the origin of a new species. A new lineage was formed by the hybridization of two different species of Darwin’s finches.

Genome sequencing reveals extensive inbreeding in Scandinavian wolves

Press Releases   •   Nov 20, 2017 16:00 GMT

Researchers from Uppsala University and others have for the first time determined the full genetic consequences of intense inbreeding in a threatened species. The large-scale genomic study of the Scandinavian wolf population is reported in Nature Ecology & Evolution.
