Pejerrey (Odontesthes bonariensis) Under Siege: Main Infectious Diseases and Their Role in Aquaculture and Wild Populations Amidst Environmental Change

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT The pejerrey (Odontesthes bonariensis) is a key species for recreational and commercial fisheries in Argentina and holds significant aquaculture potential. It has been introduced to various countries worldwide, including Japan, where intensive aquaculture has developed.

A CRISPR‐Based Rapid Detection Assay for Crayfish Plague (Aphanomyces astaci) From Environmental Samples

Journal of Fish Diseases, EarlyView.
ABSTRACT Crayfish plague, caused by Aphanomyces astaci (Aa), is an infectious disease invasive in Europe, where its rapid spread has resulted in sharp declines of native crayfish species. Monitoring currently relies on a highly sensitive, but costly and time‐consuming qPCR approach.

Investigation of Seed transmission in Peronospora belbahrii the Causal Agent of Basil Downy Mildew

Agronomy, 2019
Downy mildew in sweet basil (Ocimum basilicum L.) caused by the oomycete pathogen Peronospora belbahrii Thines was first recorded in Israel in 2011. Within one year, the pathogen has spread all over the country, causing devastating economic damage to ...

Francisella orientalis in Aquacultured Tilapia (Oreochromis spp.): A Case Work‐Up of Diagnostics and Pathologic Findings in the North Central Region (USA)

Journal of Fish Diseases, EarlyView.
ABSTRACT Tilapia (Oreochromis spp.) is an increasingly popular aquacultured fish worldwide. While tilapia enjoy a ‘hardy‐fish’ reputation among fish farmers, they are susceptible to a variety of infectious diseases that can be difficult to recognize pondside and have similarities in their gross presentations. This report describes gross and microscopic

How to Unravel the Key Functions of Cryptic Oomycete Elicitin Proteins and Their Role in Plant Disease

Plants, 2021
Pathogens and plants are in a constant battle with one another, the result of which is either the restriction of pathogen growth via constitutive or induced plant defense responses or the pathogen colonization of plant cells and tissues that cause ...

RING E3 ligase SNIPER8 functions redundantly with three close homologs to regulate the turnover of transcriptional co‐repressor TPR1

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis E3 ligase SNIPER8 negatively regulates immunity by promoting ubiquitination and proteasomal degradation of the transcriptional corepressor TOPLESS‐RELATED1, limiting excessive immune responses, maintaining immune homeostasis, and balancing defense activation and normal plant growth.

Candidate effector proteins from the oomycetes Plasmopara viticola and Phytophthora parasitica share similar predicted structures and induce cell death in Nicotiana species. [PDF]

, 2022
Effector proteins secreted by plant pathogens are essential for infection. Cytoplasmic RXLR effectors from oomycetes are characterized by the presence of RXLR and EER motifs that are frequently linked to WY- and/or LWY-domains, folds that are exclusive ...

CP32, a novel anti‐oomycete cyclic peptide, interferes with cell‐wall deposition in Phytophthora infestans

Journal of Integrative Plant Biology, EarlyView.
The small cyclic peptide CP32 effectively inhibits Phytophthora infestans, the causal agent of potato and tomato late blight. Combined biochemical and phenotypic analyses demonstrate that CP32 disrupts cell wall biosynthesis, a key process in pathogen infection, resulting in a marked reduction of disease symptoms in plants.

Distinct small RNAs are expressed at different stages of Phytophthora capsici and play important roles in development and pathogenesis

Frontiers in Genetics
Small RNAs (sRNAs) are important non-coding RNA regulators that play key roles in the development and pathogenesis of plant pathogens, as well as in other biological processes.

Invertases in Phytophthora infestans Localize to Haustoria and Are Programmed for Infection-Specific Expression

mBio, 2020
The oomycete Phytophthora infestans, the causal agent of potato and tomato blight, expresses two extracellular invertases. Unlike typical fungal invertases, the P.
