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

open access: yesPhytoFrontiers, 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

Temperature and Water Effects on the Viability of Alginate-Formulated Oospores of Pythrium Oligandrum

open access: yesJournal of Agricultural and Marine Sciences, 1998
The low germination rates of oospores hinder the use of Pythium oligandrum as a biocontrol agent of soilborne plant pathogens. To improve the reliability of oospore-inoculum of P.

Pathogen Adaptation to American (Rpv3-1) and Eurasian (Rpv29) Grapevine Loci Conferring Resistance to Downy Mildew

open access: yesPlants, 2022
Durable resistance is a key objective in genetic improvement for disease resistance in grapevines, which must survive for years in the field in the presence of adaptable pathogen populations.

Formation and Pathogenicity Variation of Oospores of Phytophthora capsici Infecting Black Pepper

open access: yesMicrobiology Indonesia, 2010
Phytophthora capsici Leonian is the causal agent of foot rot disease of black pepper (Piper nigrum L.). Foot rot disease is the most destructive disease which can cause significant economic losses of black pepper. Two mating types of P.

Survival of Oospores of Phytophthora capsici in Soil [PDF]

open access: yesPlant Disease, 2013
This study assessed survival of Phytophthora capsici oospores in soil in Illinois. Soils differing in texture and other characteristics were collected from four Illinois Counties (Champaign, Gallatin, Madison, and Tazewell), equilibrated to –0.3 MPa, and infested with oospores of P. capsici at a density of 5 × 103 oospores/g of dry soil. Samples (25 g)

Influence of Pythium oligandrum on population of Fusarium oxysporum f.sp. dianthi and development of Fusarium wilt of carnation

open access: yesPlant Protection Science, 2002
Relationship between initial oospore number of Pythium oligandrum, mode of the mycoparasite application and populationdynamics of Fusarium oxysporum f.sp. dianthi and development of Fusarium wilt of carnation was studied.

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

open access: yesPlant Genome
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.

Transcriptomic and proteomic analysis reveals wall-associated and glucan-degrading proteins with potential roles in Phytophthora infestans sexual spore development. [PDF]

open access: yesPLoS ONE, 2018
Sexual reproduction remains an understudied feature of oomycete biology. To expand our knowledge of this process, we used RNA-seq and quantitative proteomics to examine matings in Phytophthora infestans.

Phytochrome-Mediated Germination of Very Sensitive Oospores [PDF]

open access: yesPlant Physiology, 1992
The light receptor and its mode of operation were studied in photosensitive oospores of Nitella furcata subsp. megacarpa (Allen emend. Wood). Brief pulses of light activated maximal germination of post-secondary dormant oospores removed from lake sediments.
