Genomic architecture of the resistance to Phytophthora cactorum 2 (RPc2) locus in strawberry (Fragaria × ananassa)

The Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Phytophthora crown rot, caused by Phytophthora cactorum, is a soilborne disease with broad impacts on cultivated strawberry (Fragaria × ananassa). A resistance locus, RPc2, was previously identified in octoploid strawberries, but the underlying genomic architecture and causal genes remained uncharacterized.

Visualization of the impatiens downy mildew pathogen using fluorescence in situ hybridization (FISH)

Plant Methods, 2018
Background Plasmopara obducens is the biotrophic oomycete responsible for impatiens downy mildew, a destructive disease of Impatiens that causes high crop loss. Currently, there are no available methods for the microscopic detection of P.

Chemical Priming by Neonicotinoids Unveils CaNEN4 as a Susceptibility Gene Against Phytophthora capsici in Pepper

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
IMI/TMX priming induces resistance to Phytophthora capsici by balancing ROS and suppressing RNA‐seq‐identified susceptibility genes, including CaNEN4, for sustainable management of pepper Phytophthora blight. ABSTRACT The oomycete Phytophthora capsici causes Phytophthora blight, a major constraint on global pepper production.

The effect of cadmium on growth of vegetative thallus and development of generative organs of Chara vulgaris L. after short time of cultivation

Acta Societatis Botanicorum Poloniae, 2014
The effect of cadmium ions in two different concentrations (10-8M i 10-6M) on vegetative thallus, male (antheridia) and femele (oogonia) generative organs of Chara vulgaris L. was investigated.

Hydraulic effects of vessel-induced waves on early life stages of lake macrophytes

Ecological Processes
Background The impact of vessel-induced waves on macrophyte communities in lakes remains controversial, due to a lack of comprehensive assessments which also consider mechanistic effects on ecological processes during early life stages.

Sterols and the Production of Oospores by Phytophthora cactorum [PDF]

Journal of General Microbiology, 1972
SUMMARY: The effect of eight sterols on oospore production by Phytophthora cactorum has been studied quantitatively. Their activity was found to be in the following order: β-sitosterol = Δ5-avenasterol = fucosterol = stigmasterol > cholesterol = 7-dehydro-cholesterol > ergosterol > cholestanol.

Oospores of Phytphthora infestans in soil provide an important new source of primary inoculum in Finland

Agricultural and Food Science, 2008
There have been numerous indications since the 1990s that oospore-derived primary infections play an increasing role in the epidemiology of potato late blight.

Climatic drivers of Plasmopara viticola oospore germination: integrating long-term monitoring into predictive modelling

OENO One
Primary infection by Plasmopara viticola, the causal agent of grapevine downy mildew, is a critical event in viticulture, marking the onset of fungicide applications to protect grape production.
