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.

Well established theories on patterns in evolution might be wrong

Press Releases   •   Sep 27, 2018 13:23 BST

How do the large-scale patterns we observe in evolution arise? A new paper in the journal Evolution by researchers at Uppsala University and University of Leeds argues that many of them are a type of statistical artefact caused by our unavoidably recent viewpoint looking back into the past.

A handful of tiny teeth have led scientists to identify the most distant ancestor of today’s kangaroos. The fossils were found in the desert heart of Australia, and then hidden away, and almost forgotten in a museum collection for over three decades. The findings are published in the Journal of Vertebrate Paleontology.
