Functional Reproductive and Developmental Traits Differences Between Two Macrocystis Ecomorphs: Importance of Neutral Lipids

Ecology and Evolution
The kelp genus Macrocystis presents populations recognizable by distinct morphological traits, which has raised discussions on its taxonomical status.

A Validated LNA‐Modified Probe‐Based qPCR Assay for the Fast and Accurate Detection of the Root Rot Pathogen Phytophthora × cambivora on Mycelial DNA and Artificially Inoculated Chestnut Tissue

Plant Pathology, Volume 75, Issue 6, November‐December 2026.
In response to the ongoing threat posed by Phytophthora × cambivora to European Fagaceae forests, a qPCR‐LNA method has been developed in compliance with the EPPO PM7/98 standard. This robust detection system is ideal for large‐scale disease monitoring campaigns, epidemiological investigations, routine diagnostics in nurseries and other vulnerable ...

Zoospore exudates from Phytophthora nicotianae affect immune responses in Arabidopsis.

PLoS ONE, 2017
Zoospore exudates play important roles in promoting zoospore communication, homing and germination during plant infection by Phytophthora. However, it is not clear whether exudates affect plant immunity.

Differential skin microbiomes and disease outcomes in sympatric hosts despite similar infection burdens

Ecosphere, Volume 17, Issue 10, October 2026.
Abstract Amphibians are declining worldwide, in large part due to chytridiomycosis: a disease of amphibian skin caused by the fungal pathogen, Batrachochytrium dendrobatidis (Bd). Resistance and tolerance to Bd infection can exhibit intra‐ and interspecific variation. This variation may depend, among other factors, on the host skin microbiome.

Frogs, fire, and fungus: The effects of prescribed fire on frog occupancy and health in a biodiversity hotspot

Ecosphere, Volume 17, Issue 10, October 2026.
Abstract The global amphibian extinction crisis results from many threats, including anthropogenic climate change, modified fire regimes, and disease. Identifying the effects of these processes is crucial for frog conservation, especially in regions where species experience ongoing prescribed fire and chytridiomycosis.

Ex vivo observation of Pythium insidiosum-antigen treated neutrophils on three Pythium insidiosum strains isolated from vascular pythiosis patients

Human Vaccines & Immunotherapeutics
The mechanisms of Pythium insidiosum-antigen (PIA) immunotherapy activating a patient’s immune system are unknown. We evaluated the interleukin-8 (IL-8) serum levels during P.

Ranavirus risk depends on host community characteristics more than the presence of Batrachochytrium dendrobatidis

Oikos, Volume 2026, Issue 10, October 2026.
Novel parasite introductions are threatening wildlife communities globally. The degree of threat depends on the ecological context, namely host community characteristics and the presence of other parasites. How these two factors interact to shape the outcomes of parasite introductions is not known. We experimentally investigated how infection following

A novel method for efficient and abundant production of Phytophthora brassicae zoospores on Brussels sprout leaf discs

BMC Plant Biology, 2009
Background Phytophthora species are notorious oomycete pathogens that cause diseases on a wide range of plants. Our understanding how these pathogens are able to infect their host plants will benefit greatly from information obtained from model systems ...

Evolutionarily diverse fungal zoospores show contrasting swimming patterns specific to ultrastructure [PDF]

Zoosporic fungi, also called chytrids, produce single-celled motile spores with flagellar swimming tails (zoospores). These fungi are key components of aquatic food webs, acting as pathogens, saprotrophs, and prey.

Marine Macroalgae: Prospective Hitchhikers of Ship Ballast

ASEAN Journal on Science and Technology for Development, 2018
Invasive alien species, on successful establishment, can displace native species. The threat of invasive species arises in view of their ability to outcompete and destabilize native biodiversity.
