Abstract It is important to improve the understanding of interactions between trees and pathogens integrate this knowledge about disease resistance into tree breeding programs. The conifer Norway spruce ( Picea abies ) an species for forest industry in Europe. Its major pathogen Heterobasidion parviporum , causing stem root rot. In study, we identified 11 QTLs (Quantitative trait loci) that correlate with variation H. a population 466 by association genetics. Individual explained 2.1 5.2%...
The frequency and impact of drought on global ecosystems have increased within the last century, while has affected tree health in many regions. Diplodia sapinea is a widespread, opportunistic pathogen infecting most conifers, causing tip blight, thriving hosts impacted by stress such as drought, heat, or mechanical wounding. In summer 2018, large-scale was recorded all over Europe. late summer, pine trees Gotland showed crown dieback, where necrotic twigs needles were found, especially...
Abstract Ash dieback (ADB) caused by the pathogen Hymenoscyphus fraxineus is cause of massive mortality Fraxinus spp. in Europe. The aim this work was to check for presence molecular marker ADB tolerance mapped healthy‐looking F. excelsior trees, and compare its occurrence trees exhibiting severe symptoms. Monitoring 135 on island Gotland, Sweden, showed that after 3–4 years 99.3% these had 0%–10% crown damage, thus remaining a similar health condition as when first mapped. After 5–6 years,...
Common ash (Fraxinus excelsior L.) is a tree species of significant ecological and economic importance that has suffered devastating decline since the 1990s in Europe. Native are being threatened by alien invasive fungus Hymenoscyphus fraxineus, which causes dieback. The main goal study was to develop markers for traits related tolerance dieback investigate whether genotypes selected were genetically different from susceptible wild populations. We phenotyped 326 trees Sweden disease severity...
ABSTRACT Diplodia sapinea causes tip blight (DTB) and is recognised as an opportunistic necrotrophic pathogen affecting conifers. While DTB associated with abiotic stress, the impact of biotic stress in host on D. 's lifestyle shift unknown. Observed co‐occurrences Melampsora pinitorqua , causing pine twisting rust Scots ( Pinus sylvestris ), instigated investigation into their interaction influence defence mechanisms host. We hypothesised that M. infections predispose trees to by stressing...
