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

open access: yesPlant 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

open access: yesEcosphere, 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

Development of a qPCR Assay for the Detection and Quantification of the Fungal Pathogen Calonectria canadiana on Conifers

open access: yesForest Pathology, Volume 54, Issue 5, October 2024.
ABSTRACT A real‐time PCR TaqMan assay was developed for the detection of Calonectria canadiana, a fungal pathogen responsible for damping off, root rot and seedling blight in conifer forest nurseries in central and eastern North America. While highly significant in Quebec Forest nurseries, coniferous seedling mortality decreased significantly when ...
