Airborne Plasmopara viticola Sporangia: A Study of Vineyards in Two Bioclimatic Regions of Northwestern Spain

Horticulturae
Downy mildew, caused by Plasmopara viticola, is one of the most destructive diseases affecting grapevines, particularly in areas with bioclimatic conditions that favor its development, such as northwestern Spain.

Nasal Rhinosporidiosis Diagnosed by Cytology: A Case Report [PDF]

Journal of Clinical and Diagnostic Research
Rhinosporidiosis is a chronic granulomatous inflammation of mucosal sites caused by the fungus Rhinosporidium seeberi. The most common site of involvement is the nasal mucosa, followed by the lips, palate, uvula, maxillary antrum, epiglottis, larynx ...

Overcoming Detection Lag in a Cryptic Panzootic: Chytrid Invasion Linked to Historically Enigmatic Amphibian Declines in the Brazilian Atlantic Forest [PDF]

Mol Ecol
ABSTRACT As human activity accelerates the spread of pathogens and other invasive species, reconstructing the cryptic early dynamics of undetected invasions has become a central challenge in disease ecology and invasion biology. Here, we leverage museum specimens to reconstruct the invasion of Batrachochytrium dendrobatidis (Bd), a fungal panzootic ...

Fletcheria gen. nov. (Ralfsiales, Phaeophyceae): A new crustose brown algal genus clarifying evolutionary relationships of Ralfsia pacifica

Journal of Phycology, EarlyView.
Abstract The genus Ralfsia was historically broadly circumscribed but has recently undergone significant taxonomic revision. Based on molecular data, a restricted Ralfsia sensu stricto was delineated that had many species reassigned to new genera and families.

Development of detection systems for the sporangia of Peronospora destructor

, 2008
A monoclonal antibody that recognises components of the wall of sporangia of Peronospora destructor was raised. Tests using spores of higher fungi and other species of mildew demonstrated the specificity of the monoclonal.

An AGC kinase cascade regulates ROP signaling for the correct timing of pollen germination

New Phytologist, EarlyView.
Model for PDK1‐AGC1.5/7 kinase cascade function in controlling pollen germination. Summary In flowering plants, the timing of pollen germination is crucial for successful fertilization and an important trait for seed and fruit crops. Environmental factors tightly regulate pollen germination, with germination‐suppressing conditions on the pollen ...

Characteristics of monolayer formation in vitro by the chytrid Batrachochytrium dendrobatidis

Biofilm, 2019
Batrachochytrium dendrobatidis is a globally distributed generalist pathogen that has driven many amphibian populations to extinction. The life cycle of B. dendrobatidis has two main cell types, motile zoospores, and sessile reproductive sporangia.

Elevated CO2 drives nonlinear trait responses and reshapes growth‐virulence trade‐offs in a plant pathogen

New Phytologist, EarlyView.
Temporal variation in carbon dioxide concentration within the crop canopy and in the atmosphere. Summary Atmospheric CO2 is rising at unprecedented rates. While its physiological effects on plants are well‐documented, the direct evolutionary impact on plant pathogens remains unknown. We investigated how CO2 interacts with other abiotic factors to shape

Biotransformation of monoterpenols upon pre‐treatment with oregano essential oil vapour alleviates downy mildew susceptibility in grapevine leaves

Plant Biology, EarlyView.
Pre‐treatment of grapevine plants with oregano essential oil vapour alleviates downy mildew susceptibility by accumulation of monoterpenol glycosides. Abstract Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is a destructive disease that causes major economic losses as most elite grapevine cultivars are susceptible to this pathogen.

Asexual Recombinants of Plasmopara halstedii Pathotypes from Dual Infection of Sunflower. [PDF]

PLoS ONE, 2016
Genetically homogenous strains of Plasmopara halstedii differing in host specificity and fungicide tolerance were used to test the hypothesis that asexual genetic recombination occurs and may account for the high genotype diversity of this homothallic ...
