Digital droplet PCR quantification and field-scale spatial distribution of Plasmopara viticola oospores in vineyard soil [PDF]

Applied and Environmental Microbiology
Grapevine downy mildew, caused by the oomycete Plasmopara viticola, is one of the most devastating diseases affecting grapevine worldwide. Primary inoculum (i.e., oospores) plays a decisive role in downy mildew epidemics, but we still know very little ...

A novel method for extraction of high purity and high production Phytophthora sojae oospores [PDF]

Plant Methods
Background Phytophthora sojae, a soil-borne oomycete pathogen, has been a yield limiting factor for more than 60 years on soybean. The resurgence of P. sojae (Phytophthora sojae) is primarily ascribed to the durable oospores found in soil and remnants of

Relationship between the oospore dose in the leaf litter above the vineyard ground and primary infections by Plasmopara viticola [PDF]

Frontiers in Plant Science
Plasmopara viticola, the grapevine downy mildew (DM) oomycete, overwinters as oospores in fallen leaves above the vineyard ground. The oospores repeatedly germinate in the following season, causing primary infections on the leaves and clusters.

A Method for Quantifying Phytophthora Oospore Viability Using Fluorescent Dyes and Automated Image Analysis

PhytoFrontiers, 2023
Phytophthora are eukaryotic microbes that cause disease in a wide range of agriculturally and ecologically important plants. During the Phytophthora disease cycle, thick-walled oospores can be produced via homothallic or heterothallic reproduction. These

Gases Released During Soil Biodisinfestation of Pepper Greenhouses Reduce Survival of Phytophthora capsici Oospores in Northern Spain

Frontiers in Sustainable Food Systems, 2021
Phytophthora capsici is one of the oomycetes that affects protected pepper crops in different agroclimatic areas of Spain. Currently, environmentally friendly strategies such as biodisinfestation for plant disease control have become increasingly popular.

The Study of the Germination Dynamics of Plasmopara viticola Oospores Highlights the Presence of Phenotypic Synchrony With the Host

Frontiers in Microbiology, 2021
The plant disease onset is a complex event that occurs when the pathogen and the host encounter in a favorable environment. While the plant–pathogen interaction has been much investigated, little attention has been given to the phenological synchrony of ...
