Phytophthora ramorum infection of coast live oak leaves in Californian forests and its capacity to sporulate in vitro

open access: yes, 2008
Coast live oak (Quercus agrifolia) is a known host for Phytophthora ramorum, the casual agent of sudden oak death in California, with symptoms expressed as necrotic stem cankers.

The interplay between a Phytophthora RXLR effector and an Arabidopsis lectin receptor kinase

open access: yes, 2010
Phytophthora infestans – the causal agent of potato late blight – secretes a plethora of effector proteins to facilitate plant infection. The central subject of this thesis is ipiO, one of the first cloned Phytophthora genes with a putative function in ...

Under the Cover of Darkness: A Transcriptomic Exploration of Clubroot During the Night

open access: yesPlant Direct, Volume 10, Issue 6, June 2026.
ABSTRACT Plasmodiophora brassicae (Phytomyxea, Rhizaria) is the etiological agent of clubroot disease, one of the most important diseases of Brassicaceae crops. Alteration of metabolism and hormone homeostasis leads to the formation of tumor‐like galls in the roots of affected plants.

Biological Pesticides as Viable Alternative to Synthetic Pesticides for Sustainable Agriculture and Nutrition: A Systematic Review

open access: yesJournal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT The overuse of synthetic pesticides in agriculture has raised significant environmental and health concerns. Biopesticides have emerged as viable, environmentally compatible alternatives. However, recent comprehensive reviews integrating all biopesticide categories and emphasizing their contribution to synthetic‐pesticide‐free and health‐safe ...

Genetic architecture of angular leaf spot resistance in cultivated strawberry shaped by epistasis and genotype‐by‐environment interactions

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Angular leaf spot (ALS), caused by Xanthomonas fragariae, is a bacterial disease that limits strawberry (Fragaria × ananassa) productivity worldwide. Although major resistance loci have been identified in wild Fragaria species, their introgression into elite germplasm remains constrained by linkage drag and inconsistent inheritance. To dissect

In vitro evaluation of resistance of potato cultivars to Phytophthora infestans

open access: yes, 1999
The resistance of ten potato cultivars (Agria, Ajax, Désirée Liseta, Kennebec, Majestic, Monalisa, Prima, Spunta and Tonda di Berlino) to Phytophthora infestans was analyzed in vitro using 8 fungal strains.

Exploring the Antifungal Potential of the Brown Macroalga Hormophysa triquetra: Morphological Disruptions and Structural Changes in Plant Pathogens

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Extracts of Hormophysa triquetra showed antifungal activity with marked hyphal deformities in Fusarium oxysporum and Alternaria alternata. Light microscopy and SEM confirmed structural alterations despite unchanged radial growth. Cucumber assays validated reduced disease incidence, linked to fatty‐acid–rich metabolites detected by GC–MS.
