Inoculum dose–disease response relationships for the pea root rot pathogen, Aphanomyces euteiches, are dependent on soil type and other pathogens [PDF]
Frontiers in Plant Science, 2023 The oomycete pathogen, Aphanomyces euteiches, was implicated for the first time in pea and lentil root rot in Saskatchewan and Alberta in 2012 and 2013.

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

Plastid DNA sequences and oospore characters of some European taxa of Tolypella section Tolypella (Characeae) identify five clusters, including one new cryptic Tolypella taxon from Sardinia, but they do not coincide with current morphological descriptions [PDF]
Frontiers in Plant Science, 2023 In Europe, the genus Tolypella (Characeae) comprises four to eight Tolypella taxa in sections Rothia and Tolypella that have been distinguished by vegetative morphology and gametangial characters such as antheridial size and oospore wall ornamentation ...

A Protein with Unknown Function, Ps495620, Is Critical for the Sporulation and Oospore Production of Phytophthora sojae [PDF]
Journal of FungiWhile the rapid rise in bioinformatics has facilitated the identification of the domains and functions of many proteins, some still have no domain annotation or largely uncharacterized functions. However, the biological roles of unknown proteins were not

Relationship between the oospore dose in the leaf litter above the vineyard ground and primary infections by Plasmopara viticola [PDF]
Frontiers in Plant SciencePlasmopara 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 Phytophthora receptor-like kinase regulates oospore development and can activate pattern-triggered plant immunity [PDF]
Nature Communications, 2023 Plant cell-surface leucine-rich repeat receptor-like kinases (LRR-RLKs) and receptor-like proteins (LRR-RLPs) form dynamic complexes to receive a variety of extracellular signals.

A Novel FYVE Domain-Containing Protein Kinase, PsZFPK1, Plays a Critical Role in Vegetative Growth, Sporangium Formation, Oospore Production, and Virulence in Phytophthora sojae [PDF]
Journal of Fungi, 2023 Proteins containing both FYVE and serine/threonine kinase catalytic (STKc) domains are exclusive to protists. However, the biological function of these proteins in oomycetes has rarely been reported.

Life and death: the destiny of Phytophthora sojae determined by a receptor-like kinase [PDF]
Stress Biology, 2023 Leucine-rich repeat receptor-like kinases (LRR-RLKs) are well known to act in plant growth, development, and defense responses. Plant LRR-RLKs locate on cell surface to sense and initiate responsive signals to a variety of extracellular stimuli, such as ...

Vertical distribution of Phytophthora agathidicida oospore DNA in kauri forest soils: implications for optimized sampling and disease monitoring [PDF]
Microbiology SpectrumPhytophthora species are globally significant soilborne oomycetes responsible for widespread ecosystem decline. Standard soil sampling protocols, originally developed for qualitative baiting assays, typically require collecting substantial soil volumes ...

Evaluating the contribution of historical and contemporary temperature to the oospore production of self‐fertile Phytophthora infestans [PDF]
Evolutionary ApplicationsReproductive systems play an important role in the ecological function of species, but little is known about how climate change, such as global warming, may affect the reproductive systems of microbes.
