Variation in host and pathogen in the Neonectria/Malus interaction; towards an understanding of the genetic basis of resistance to European canker

Frontiers in Plant Science, 2016
Apple canker caused by the phytopathogenic fungus Neonectria ditissima is an economically important disease, which has spread in recent years to almost all pome-producing regions of the world. N.

Phylogenetic analysis shows that New Zealand isolates of Neonectria ditissima are similar to European isolates

New Zealand Plant Protection, 2021
Neonectria ditissima causes a debilitating apple tree canker disease. We determined the efficacy of polymerase chain reaction primers, originally designed for European strains, by sequencing New Zealand strains. The concatenated ribosomal inter-transcribed spacer and β-tubulin gene regions of 17 New Zealand isolates were compared with those of two ...

Methods for the Quantification of Resistance of Apple Genotypes to European Fruit Tree Canker Caused by Neonectria ditissima [PDF]

Plant Disease, 2017
European fruit tree canker, caused by Neonectria ditissima, is an important disease of pome fruit worldwide. Apple cultivars differ in their levels of susceptibility to N. ditissima. In order to design an effective plant resistance test, we examined the effectiveness of two resistance parameters: infection frequency and lesion growth.

Homoterpen‐Biosynthese in Pilzen

Angewandte Chemie, Volume 137, Issue 52, December 22, 2025.
Der erste Homoterpen‐Biosyntheseweg im Reich der Pilze. Ein Methyltransferase und Terpenzyklase Paar bildet über Presodorifen ein einzigartiges Heptamethyl‐bicyclo[3.3.1]nonan‐Homoterpen. Dies zeigt, dass Homoterpen‐Biosynthese durch Addition einer C1‐Einheit an Terpendiphosphat‐Vorläufer vor Gerüstbildung nicht auf Bakterien beschränkt ist, sondern ...

The Effects of Arbuscular Mycorrhizal Fungal Colonisation on Nutrient Status, Growth, Productivity, and Canker Resistance of Apple (Malus pumila)

Frontiers in Microbiology, 2018
We assess whether arbuscular mycorrhizal fungi (AMF) improve growth, nutritional status, phenology, flower and fruit production, and disease resistance in woody perennial crops using apple (Malus pumila) as a study system. In a fully factorial experiment,

The effect of nitrogen source on in vitro growth of Neonectria ditissima (European canker)

New Zealand Plant Protection, 2018
Nitrogen fertilisers are widely used in apple orchards. However, the effects of various nitrogen sources on growth and sporulation of the fungus Neonectria ditissima, which causes European canker, are not fully understood. The effects of various nitrogen sources commonly used in apple orchards (potassium nitrate, ammonium chloride, ammonium nitrate ...

Environmental Requirements for Germination and Appressorium Formation of Ascospores and Conidia of Phyllosticta citricarpa, the Causal Agent of Citrus Black Spot

Plant Pathology, Volume 74, Issue 7, Page 2108-2120, September 2025.
Cardinal temperatures for both Phyllosticta citricarpa spore germination were estimated as ~10ºC (minimum) and ~40ºC (maximum), and the optimum temperatures were ~30ºC for ascospores and ~24ºC for conidia. ABSTRACT Phyllosticta citricarpa produces ascospores and conidia that infect citrus tissues and cause citrus black spot (CBS).
