Establishment of a simple and efficient Agrobacterium-mediated transformation system for Phytophthora palmivora [PDF]

open access: yes, 2016
BACKGROUND: As an agriculturally important oomycete genus, Phytophthora contains a large number of destructive plant pathogens that severely threaten agricultural production and natural ecosystems. Among them is the broad host range pathogen P. palmivora,

Effects of temperature on sexual competition in three kelp species, Pterygophora californica, Nereocystis luetkeana, and Macrocystis pyrifera: Implications for range shifts in foundation species

open access: yesPhycological Research, Volume 74, Issue 2, Page 107-115, April 2026.
SUMMARY Kelp forests are threatened by rising ocean temperatures. However, the effects of warming on early life stage interactions among co‐occurring kelp species, particularly competitive dynamics and reproductive timing, remain poorly understood. This study investigates the effects of temperature on embryonic sporophyte competitive interactions and ...

New Phytophthora populations: A shift from indirect to direct sporangial germination? [PDF]

open access: yes, 2009
Phytophthora infestans, the causal agent of potato- and tomato late blight, remains a serious threat for (commercial) potato and tomato production. In North Western Europe, frequent fungicide applications, mostly aimed to prevent infection, form the back

PsSAK1, a Stress-Activated MAP Kinase of Phytophthora sojae, Is Required for Zoospore Viability and Infection of Soybean

open access: yesMolecular Plant-Microbe Interactions, 2010
Mitogen-activated protein kinase (MAPK) pathways are universal and evolutionarily conserved signal transduction modules in all eukaryotic cells. In this study, PsSAK1, which encodes a stress-activated MAPK of Phytophthora sojae, was identified. PsSAK1 is

Effects of Temperature on Sexual Competition in Kelps: Implications for Range Shifts in Foundation Species [PDF]

open access: yes, 2014
Kelp populations inhabit some of the most dynamic environments on the planet and often exist close to the limits of their temperature tolerances.

Overexpression of Nictaba-like lectin genes from glycine max confers tolerance towards Pseudomonas syringae infection, aphid infestation and salt stress in transgenic Arabidopsis plants [PDF]

open access: yes, 2016
Plants have evolved a sophisticated immune system that allows them to recognize invading pathogens by specialized receptors. Carbohydrate-binding proteins or lectins are part of this immune system and especially the lectins that reside in the ...

Oomycete Plant Pathogens Use Electric Fields to Target Roots

open access: yesMolecular Plant-Microbe Interactions, 2002
Plant roots generate electrical currents and associated electrical fields as a consequence of electrogenic ion transport at the root surface. Here we demonstrate that the attraction of swimming zoospores of oomycete plant pathogens to plant roots is ...

Dynamic Extreme Aneuploidy (DEA) in the vegetable pathogen Phytophthora capsici and the potential for rapid asexual evolution.

open access: yesPLoS ONE, 2020
Oomycete plant pathogens are difficult to control and routine genetic research is challenging. A major problem is instability of isolates. Here we characterize >600 field and single zoospore isolates of Phytophthora capsici for inheritance of mating type,

Phytophthora root and collar rot in rehabilitated bauxite mines and the adjacent Eucalyptus marginata (Jarrah) forest of Western Australia [PDF]

open access: yes, 2000
This study gives an overview of recent and current research activities that are being conducted in Western Australia on the biology, ecology and pathology of Phytophthora cinnamomi in rehabilitated bauxite mines and the adjacent jarrah (Eucalyptus ...

Efficacy of chemical disinfectants for the containment of the salamander chytrid fungus Batrachochytrium salamandrivorans [PDF]

open access: yes, 2017
The recently emerged chytrid fungus Batrachochytrium salamandrivorans (Bsal) causes European salamander declines. Proper hygiene protocols including disinfection procedures are crucial to prevent disease transmission.
