Phytophthora zoospores display klinokinetic behaviour in response to a chemoattractant.

PLoS Pathogens
Microswimmers are single-celled bodies powered by flagella. Typical examples are zoospores, dispersal agents of oomycete plant pathogens that are used to track down hosts and infect.

Zoosporulation of a new Perkinsus species isolated from the gills of the softshell clam Mya arenaria

Parasite, 2000
A gill-associated Perkinsus sp. isolated from the softshell clam (Mya arenaria) is described as a new species, P. chesapeaki sp. nov. Examination of the parasite in seawater cultures revealed life cycle stages and zoosporulation processes similar to ...

Genes expressed in zoospores of Phytophthora nicotianae

Molecular Genetics and Genomics, 2003
The genus Phytophthora includes many highly destructive plant pathogens. In many Phytophthora species, pathogen dispersal and initiation of plant infection are achieved by motile, biflagellate zoospores that are chemotactically attracted to suitable infection sites.

Interactional Endocytosis and Transmembrane Transport Promote Cellular Internalization of Nano‐Delivered RNA Drugs for Efficient Control of Crop Diseases

Plant Biotechnology Journal, EarlyView.
ABSTRACT Botrytis cinerea is a widespread plant pathogenic ascomycete that causes grey mould in over 1400 species and impacts global crop yields. Double‐stranded RNA (dsRNA)‐induced gene silencing is a promising technology for pest control, but efficient delivery remains a major challenge.

Alcoholic extracts of Russian sage (Salvia yangii) contain bioactive terpenoids with inhibitory activity against grapevine downy mildew (Plasmopara viticola)

Pest Management Science, Volume 82, Issue 9, Page 8159-8170, September 2026.
Alcoholic extracts from flowers, leaves, and shoots of Russian sage decreased downy mildew severity on grapevine leaf disks. Fractionation followed by metabolomic analysis revealed putative terpenoids as the main components of the active fractions. Specifically, 7‐methylrosmanol, 12‐O‐methylcarnosic acid, carnosic acid, and carnosol were identified as ...

Transcriptomic and Ultrastructural Signatures of K⁺-Induced Aggregation in Phytophthora parasitica Zoospores

Microorganisms, 2020
Most pathogenic oomycetes of the genus Phytophthora spread in water films as flagellated zoospores. Zoospores perceive and produce signals attracting other zoospores, resulting in autoaggregation in vitro or biofilm formation on plant surface.

The evolutionary origins of streptophyte multicellularity

New Phytologist, Volume 251, Issue 5, Page 2365-2383, September 2026.
The phylogeny of streptophytes and the deep origin of branching filamentous growth. Summary Over their more than 1 billion years of evolutionary history, streptophytes have repeatedly transitioned between unicellular, simple multicellular and complex multicellular forms.

Salamander–Batrachochytrium salamandrivorans Interactions Through Dual Transcriptomics

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Using dual transcriptomics, this study reveals how salamanders defend against an emerging pathogen and how the pathogen infects multiple hosts, uncovering a novel calmodulin‐mediated virulence pathway. These mechanistic insights connect molecular responses to host susceptibility, advancing our understanding of the potential impacts of disease on ...

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

Computational 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.
