First Genetic Clues to Fight Dieback

March 19, 2014

Researchers from the University of York in collaboration with John Innes Centre and other research institutions investigated the genetic clues that could help develop trees tolerant to ash dieback. Dr. Martin Trickfrom JIC used the data generated by The Genome Analysis Centre and developed a catalogue of genetic variations of most resistant Danish trees strain known asTree 35 that led to disease resistance. He also recorded how highly the genes were expressed, and found that the activity of some genes seems to be linked with disease resistance.

"We are now at the stage of being able to say that if specific genes in a certain tree are expressing at particular levels, that tree is likely to be less susceptible to ash dieback," said Professor Ian Bancroft. "We expect soon to be able to identify the genes that control the expression of these marker genes," he added.

The research teams will confirm that these markers are good predictors of disease susceptibility in the field and to start testing if UK trees exhibit similar genetic patterns linked with resistance.
