Activity Against Pythium insidiosum and Isolated Constituents of Cordia insignis Roots

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
This study investigates the roots of Cordia insignis in search of novel treatments for pythiosis, caused by the oomycete Pythium insidiosum. Seven compounds are isolated, including steroids, a saponin, a coumarin, a fatty acid, and a glycoside, the latter two are reported for the first time in the genus.

Phytophthora zoospores: From perception of environmental signals to inoculum formation on the host-root surface

open access: yesComputational and Structural Biotechnology Journal, 2020
To explore moist soils and to target host plants, phytopathogenic Phytophthora species utilize the sensory and propulsion capabilities of the biflagellate unicellular zoospores they produce.

Metabolomic Analysis of Phytophthora parasitica Growth in the Presence of β‐sitosterol Indicates Adaptive Mechanisms Modulated by Sterols

open access: yesJournal of Basic Microbiology, Volume 66, Issue 2, February 2026.
ABSTRACT Phytophthora parasitica is a generalist phytopathogenic oomycete that infects a series of crops with great economic interest, including tomato, tobacco, and citrus species. Sterols are essential lipids in eukaryotic organisms, playing a fundamental role in the structure and function of the cell membrane.

Unraveling the senses of Phytophthora; leads to novel control strategies? [PDF]

open access: yes, 2009
Oomycetes cause devastating diseases on plants and animals. They cause major yield losses in many crop plants and their control heavily depends on agrochemicals. This is certainly true for the potato late blight pathogen Phytophthora infestans.

Rapid toxicity assessment of six antifouling booster biocides using a microplate-based chlorophyll fluorescence in Undaria pinnatifida gametophytes [PDF]

open access: yes, 2020
Biocides of antifouling agents can cause problems in marine ecosystems by damaging to non-target algal species. Aquatic bioassays are important means of assessing the quality of water containing mixtures of contaminants and of providing a safety standard

Glycoside Hydrolase CaGH17‐12 Contributes to Phytophthora Blight Resistance by Activating the Production of Reactive Oxygen Species and Jasmonic Acid Signalling in Pepper

open access: yesMolecular Plant Pathology, Volume 27, Issue 2, February 2026.
Glycoside hydrolase 17 family gene CaGH17‐12 contributes to P. capsici resistance by degrading pathogen‐derived β‐glucans and generating β‐glucan oligosaccharides, thereby triggering downstream JA signalling and ROS‐mediated defence responses. ABSTRACT Glycoside hydrolase family 17 (GH17) plays a critical role in degrading pathogen cell walls and is ...
