Host–Pathogen Interactions in Leaf Petioles of Common Ash and Manchurian Ash Infected with Hymenoscyphus fraxineus [PDF]

open access: yesMicroorganisms, 2022
Some common ash trees (Fraxinus excelsior) show tolerance towards shoot dieback caused by the invasive ascomycete Hymenoscyphus fraxineus. Leaf petioles are considered to serve as a pathogen colonization route to the shoots.

Genetic resources of common ash (Fraxinus excelsior L.) in Poland [PDF]

open access: yesBMC Plant Biology
Background Knowledge of genetic structure and the factors that shape it has an impact on forest management practices. European ash (Fraxinus excelsior L.) has declined dramatically throughout its range as a result of a disease caused by the fungus ...

Genetic Structure in the Northern Range Margins of Common Ash, Fraxinus excelsior L. [PDF]

open access: yesPLoS ONE, 2016
During post glacial colonization, loss of genetic diversity due to leading edge effects may be attenuated in forest trees because of their prolonged juvenile phase, allowing many migrants to reach the colonizing front before populations become ...

Gene flow of common ash (Fraxinus excelsior L.) in a fragmented landscape. [PDF]

open access: yesPLoS ONE, 2017
Gene flow dynamics of common ash (Fraxinus excelsior L.) is affected by several human activities in Central Europe, including habitat fragmentation, agroforestry expansion, controlled and uncontrolled transfer of reproductive material, and a recently ...

A first assessment of Fraxinus excelsior (common ash) susceptibility to Hymenoscyphus fraxineus (ash dieback) throughout the British Isles. [PDF]

open access: yesSci Rep, 2017
Ash dieback (ADB), caused by Hymenoscyphus fraxineus, has severely damaged a large proportion of ash trees (Fraxinus excelsior) in continental Europe. We have little damage data for the British Isles where the disease was found only five years ago in the

Fraxinus excelsior: Common Ash

open access: yesEDIS, 2014
Common Ash is a broad, spreading, deciduous tree, capable of reaching 100 feet or more in height but most often seen growing at a moderate pace at 70 to 80 feet with a 60 to 90-foot spread.

Transcriptional responses in developing lesions of European common ash (Fraxinus excelsior) reveal genes responding to infection by Hymenoscyphus fraxineus. [PDF]

open access: yesBMC Plant Biol, 2020
Background With the expanding ash dieback epidemic that has spread across the European continent, an improved functional understanding of the disease development in afflicted hosts is needed.

Mother trees of common ash (Fraxinus excelsior) disperse different sets of mycobiome through their seed wings [PDF]

open access: yesBMC Research Notes
Objective The endophytic mycobiome is present in all studied plant compartments, including fruits and seeds. Here, we studied the mycobiome of seed wings as they are transferred with seeds in common ash and tested whether the mycobiome differs among ...
