Detecting the asymptomatic colonization of apple branches by Neonectria ditissima, causing European canker of apple

open access: yesEuropean Journal of Plant Pathology, 2023
European canker is one of the most devastating fungal diseases of apple in most temperate regions. The causal agent, Neonectria ditissima , infects trees through wounds in the bark forming cankers that girdle the stem and eventually cause tree death ...

Apple rootstocks may become infected by Neonectria ditissima during propagation

open access: yesActa Agriculturae Scandinavica. Section B, Soil and Plant Science, 2018
Introduction and purpose: The ability of apple rootstocks to become infected by Neonectria ditissima, the cause of European canker, was studied over two years.

Methods for quantifying rain-splash dispersal of Neonectria ditissima conidia in apple canopies

open access: yesFrontiers in Horticulture, 2023
Many microorganisms can be dispersed by rain-splash, whereby spores become suspended in water and are spread via droplets. The resulting dispersal gradient is dependent on several factors including rainfall intensity, the nature of the plant canopy and ...

European apple canker: morphophysiological variability and pathogenicity in isolates of Neonectria ditissima in southern Brazil

open access: yesCiência Rural, 2017
: European apple canker (EC) is caused by Neonectria ditissima, a pathogen officially registered as a quarantine pest in 2012. Thirty-five isolates of N. ditissima of different geographical regions of southern Brazil from apple branches showing symptoms

Homoterpene Biosynthesis in Fungi. [PDF]

open access: yesAngew Chem Int Ed Engl
The first homoterpene biosynthetic pathway in the fungal kingdom is reported. A methyltransferase–terpene cyclase pair produces a unique heptamethyl bicyclo[3.3.1]nonane homoterpene via presodorifen, demonstrating that homoterpene biosynthesis via the addition of a C1 unit to terpene diphosphate precursors prior to scaffold formation extends beyond the

Characterization of mating type genes in heterothallicNeonectriaspecies with emphasis onN. coccinea, N. ditissima,andN. faginata [PDF]

open access: yesMycologia, 2020
AbstractNeonectria ditissimaandN. faginataare canker pathogens involved in an insect-fungus disease complex of American beech (Fagus grandifolia) commonly known as beech bark disease (BBD). In Europe, bothN. ditissimaandN. coccineaare involved in BBD on European beech (Fagus sylvatica).

The distribution of beech leaf disease and the causal agents of beech bark disease (Cryptoccocus fagisuga, Neonectria faginata, N. ditissima) in forests surrounding Lake Erie and future implications

open access: yesForest Ecology and Management, 2022
Abstract Over the past century, beech bark disease has dramatically altered the composition and structure of stands containing American beech (Fagus grandifolia). Management of beech bark disease has focused on reducing beech thickets and identifying resistant trees in aftermath forests. Beech leaf disease is a recently detected invasive disease, now

Fungicide Sensitivity in the European Canker Fungus, Neonectria ditissima

open access: yesErwerbs-obstbau, 2023
Neonectria ditissima is one of the most serious pathogens of apple trees in temperate climatic zones, causing bark canker as well as pre- and post-harvest fruit rots. Control of fruit rots in particular is hampered by uncertainty about the sensitivity to,

Pathogen and Endophyte Assemblages Co-vary With Beech Bark Disease Progression, Tree Decline, and Regional Climate

open access: yesFrontiers in Forests and Global Change, 2021
Plant–pathogen interactions are often considered in a pairwise manner with minimal consideration of the impacts of the broader endophytic community on disease progression and/or outcomes for disease agents and hosts.

Infection biology as the basis of integrated control of apple canker (Neonectria ditissima) in Northern Europe

open access: yesCABI Agriculture and Bioscience, 2021
European canker, caused by Neonectria ditissima, is a disease of worldwide importance in apple production, yet knowledge about it is limited, highly regional and sometimes contradictory. This is an obstacle to successful disease management.
