DNA sequencing shows young trees are more likely to have gene variants that confer partial resistance to a fungus that has ...

Natural selection is acting upon thousands of locations within the ash tree DNA, driving the evolution of resistance as the ...

Ash dieback, which was first seen in the UK in 2012, causes leaf loss and crown dieback and can lead to tree death, with fears it could wipe out up to 85% of Britain’s native ash trees, as they ...

Ash trees are evolving resistance to a fungus which has decimated the species in recent years, a new study shows.

Because the fungus takes much longer to kill large trees than young ones, Buggs’s team was able to compare the genomes of 128 adult European ash trees (Fraxinus excelsior) and 458 saplings at a ...
