Evidence for the Widespread Occurrence of Bacteria Implicated in Acute Oak Decline from Incidental Genetic Sampling.
Acute Oak Decline (AOD) is complex syndrome affecting Britain’s keystone native oak species, (Quercus robur L. and Q. petraea L. (Matt.) Liebl.), in some cases causing mortality within five years of symptom development. The most distinguishable symptom is weeping stem lesions, from which four species of bacteria have been isolated:... -

Convergent molecular evolution among ash species resistant to the emerald ash borer
Recent studies show that molecular convergence plays an unexpectedly common role in the evolution of convergent phenotypes. We exploited this phenomenon to find candidate loci underlying resistance to the emerald ash borer (EAB, Agrilus planipennis), the United States’ most costly invasive forest insect to date, within the pan-genome of ash...Kelly, Laura J. ; Plumb, William J. ; Carey, David W. ; Mason, Mary E. ; Cooper, Endymion D. …

Genomic basis of European ash tree resistance to ash dieback fungus
Populations of European ash trees (Fraxinus excelsior) are being devastated by the invasive alien fungus Hymenoscyphus fraxineus, which causes ash dieback. We sequenced whole genomic DNA from 1,250 ash trees in 31 DNA pools, each pool containing trees with the same ash dieback damage status in a screening trial and...Stocks, Jonathan J. ; Metheringham, Carey L. ; Plumb, William J. ; Lee, Steve J. ; Kelly, Laura J. …

The viability of a breeding programme for ash in the British Isles in the face of ash dieback
To evaluate the viability and feasibility of a future breeding programme to produce trees resistant to an emerging pest or pathogen, it is helpful to ask the following questions: How much variation in resistance exists in tree populations? To what extent is this resistance heritable? How many genetic loci are...Plumb, William J. ; Coker, Timothy L. R. ; Stocks, Jonathan ; Woodcock, Paul ; Quine, Christopher …
