Effects of Antibiotic and Temperature Treatments on Phycosphere Bacterial Communities of Kelp Gametophytes

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 5, October 2026.
We reveal antibiotics drive qualitative turnover, while temperature induces quantitative fluctuations in kelp gametophyte microbiomes. This 15°C growth‐pathogen trade‐off guides precision seedling management. ABSTRACT Microbiome dysbiosis represents a critical bottleneck in sustainable kelp aquaculture, yet the distinct regulatory mechanisms of ...

Giant kelp (Macrocystis pyrifera) gametophytes grow endophytically in red macroalgae: Implications for kelp restoration

open access: yesJournal of Phycology, Volume 62, Issue 5, Page 1633-1644, October 2026.
Abstract Giant kelp (Macrocystis pyrifera) forests have declined by 95% in Australia since the 1970s due to climate change. Despite expanding restoration efforts, long‐term recovery is still lacking. Factors influencing recruitment by the microscopic gametophyte phase may represent a key mechanism underpinning the successful recovery and restoration of

TREATMENT AND OUTCOME OF HORSES WITH CUTANEOUS PYTHIOSIS, AND META-ANALYSIS OF SIMILAR REPORTS

open access: yesSlovenian Veterinary Research, 2019
Pythiosis is reported to be one of the most life-threatening infections of people and animals in tropical, subtropical and temperate areas worldwide. Infection can result from ingesting zoospores of Pythium insidiosum organism or from contact with water

INFLUENCIA DE LAS CONDICIONES DE INCUBACIÓN SOBRE LA ACTIVACIÓN DE ZOOSPORAS DE Spongospora subterranea, EN BUSCA DE UN INÓCULO PARA EL ESTUDIO DE LA SARNA POLVOSA INFLUENCE OF INCUBATION CONDITIONS ON THE ACTIVATION OF ZOOSPORES OF Spongospora subterranea, SEARCHING FOR AN INOCULUM TO THE STUDY OF THE POWDERY SCAB

open access: yesRevista Facultad Nacional de Agronomía Medellín, 2009
La sarna polvosa es una enfermedad que decrece la producción de papa. Es causada por el parásito obligado Spongospora subterranea f. sp. subterranea, el cual produce grupos de zoosporas enquistadas llamados quistosoros. Cuando las zoosporas están activas

Studies on Zoospore Attracting Activity. II. Synthesis of Isoflavones and Their Attracting Activity to Aphanomyces euteiches Zoospore.

open access: yesBiological and Pharmaceutical Bulletin, 1993
Nineteen isoflavones were synthesized and their attracting activity to Aphanomyces euteiches zoospore were investigated. Isoflavones (1, 2, 4, 16 and 19) with an unsubstituted B ring were synthesized by the oxidation of corresponding 2'-hydroxychalcones with thallium (III) nitrate trihydrate in methanolic perchloric acid.

Pythium insidiosum's zoospores survival fraction after PDT treatment using methylene blue at 100 µg/mL.

open access: yes, 2014
MB refers to the zoospores incubated only in the dye for 120/cm2. 30, 60 and 120 represents the zoospores incubated with these different times and then irradiated with 70 J/cm2.

Comparing the infection biology of Plasmodiophora brassicae primary and secondary zoospores in host and non-host

open access: yes, 2022
Plasmodiophora brassicae (Wor.) is an obligate plant pathogen affecting Brassicae worldwide. The cycle of P.brassicae consists of a primary phase by primary zoospores infection in root hairs and followed a secondary phase by secondary zoospores infection

Studies on the cell surface of zoospores and cysts of the fungus Phytophthora cinnamomi: nature of the surface saccharides as determined by quantitative lectin binding studies.

open access: yes, 1985
The nature of the surface saccharides of zoospores, "partially encysted zoospores" and cysts of the root-rotting fungus Phytophthora cinnamomi, has been examined by quantitative lectin binding studies. Zoospores bound concanavalin A (Con A), but did not

Temperature and inoculation method influence disease phenotypes and mortality of Eucalyptus marginata clonal lines inoculated with Phytophthora cinnamomi [PDF]

open access: yes, 2002
Survival of 1-year-old plants of three clonal lines of Eucalyptus marginata (jarrah), two ranked as resistant (RR1 and RR2) and one as susceptible (SS1) to Phytophthora cinnamomi, was assessed after pathogen inoculation with either mycelial mats ...
