Volatile organic compounds associated with neonectria ditissima infection in apples (Malus pumila cv Gala) [PDF]

Postharvest diseases in apples during long term storage result in loss and waste. This is mainly caused by fungal pathogens. Fungal contamination and rot can change some of the volatile organic compounds (VOC) emitted by apple fruits.

Neonectria Canker Disease of Fir Caused by Neonectria neomacrospora in Austria

Plant Pathology, Volume 75, Issue 3, May–June 2026.
The fir pathogen Neonectria neomacrospora is first reported on 17 Austrian localities, causing dieback and mortality on Abies alba at cool‐moist sites. A growth experiment on agar presented optimum growth at ~20°C. Moreover, an inoculation experiment revealed higher mortality on A. concolor than A. alba, while Picea abies remained unaffected.

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 ...

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).

Special delivery: A hardwood‐killing bark beetle vectors its unusual symbiote among host trees

Ecosphere, Volume 16, Issue 5, May 2025.
Abstract In mutualistic symbioses with fungi, herbivorous insects such as bark beetles (Coleoptera: Curculionidae: Scolytinae) gain access to resources that are unavailable in the absence of fungal mutualists, while fungi benefit from insect‐vectored dispersal. The most well‐studied mutualists of tree‐killing bark beetles in conifer systems are certain
