BABA-Induced DNA Methylome Adjustment to Intergenerational Defense Priming in Potato to Phytophthora infestans

Frontiers in Plant Science, 2019
We provide evidence that alterations in DNA methylation patterns contribute to the regulation of stress-responsive gene expression for an intergenerational resistance of β-aminobutyric acid (BABA)-primed potato to Phytophthora infestans.

Negative Frequency‐Dependent Selection Promotes Strain Structure in a Plant Pathogen

Ecology Letters, Volume 29, Issue 1, January 2026.
Strains of the plant pathogen Pseudomonas syringae, defined by the combination of virulence factors known as effectors, exhibit in isolates from the Midwestern US a modular population structure congruent with core genome phylogeny. A stochastic and individual‐based computational model supports a role of negative frequency‐dependent selection in ...

Research Regarding the Simultaneous Control of the Pathogens on Tomatoes Crops under High Plastic Tunnels

Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Horticulture, 2017
In Romania the most important pathogens on tomatoes crops are Alternaria porri f.sp. solani, Botrytis cinerea, Fulvia fulva, Phytophthora infestans and Erysiphe sp. During period of vegetation, the attack of mentioned pathogens are frequently overlapping.

The Roles of Plant MicroRNAs in Defence Against Pathogens

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
miRNAs modulate plant immunity against various pathogens, including fungi, bacteria, viruses, nematodes and oomycetes, by targeting pathogen effectors and modulating hormonal signalling. ABSTRACT MicroRNAs (miRNAs) are a class of noncoding RNAs that play important roles in regulating gene expression.

A Mating-Induced Protein of Phytophthora infestans Is a Member of a Family of Elicitors with Divergent Structures and Stage-Specific Patterns of Expression

Molecular Plant-Microbe Interactions, 2003
Five members of an elicitor-like gene family from Phytophthora infestans were examined. The family was identified through the analysis of M81, a mating-induced gene. The predicted M81 product resembled a 42-kDa P.

The Ralstonia solanacearum E3 Ligase Effector RipV1 Targets Plant U‐Box Domain‐Containing Receptor‐Like Cytoplasmic Kinases That Negatively Regulate Immunity in Nicotiana benthamiana

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
The Ralstonia solanacearum Novel E3 Ligase effector RipV1 ubiquitinates and enhances the accumulation of the plant U‐box‐containing receptor‐like cytoplasmic protein RLCK‐IXb‐1 that negatively regulates immune signalling. ABSTRACT Plants detect microbe‐associated molecular patterns from pathogens via plasma membrane‐localised receptors, which activate ...

ANTAGONISTIC ACTIVITY OF PLANT-ASSOCIATED MICROORGANISMS AGAINST Phytophthora infestans

Acta Scientiarum Polonorum: Hortorum Cultus, 2016
Phytophthora infestans is a pathogen threatening potato and tomato tillages. Environmentally safe biological methods are searched for the prevention against this pathogen. Many biocontrolling agents occur in plants or on their surfaces. Our studies were

The aspartic proteinase family of three Phytophthora species

BMC Genomics, 2011
Background Phytophthora species are oomycete plant pathogens with such major social and economic impact that genome sequences have been determined for Phytophthora infestans, P. sojae and P. ramorum. Pepsin-like aspartic proteinases (APs) are produced in

Phytophthora infestans effector SFI3 targets potato UBK to suppress early immune transcriptional responses.

New Phytologist, 2019
The potato blight agent Phytophthora infestans secretes a range of RXLR effectors to promote disease. Recent evidence indicates that some effectors suppress early pattern-triggered immunity (PTI) following perception of microbe-associated molecular ...

A Core Effector MoPce1 Is Required for the Pathogenicity of Magnaporthe oryzae by Modulating Catalase‐Mediated H2O2 Homeostasis in Rice

Molecular Plant Pathology, Volume 27, Issue 1, January 2026.
MoPce1, an atypical CAP/PR‐1 family effector, is essential for Magnaporthe oryzae virulence. MoPce1 functions by interacting with the rice catalase OsCATC to disrupt ROS homeostasis, thereby promoting host susceptibility. ABSTRACT Plant pathogens employ a diverse array of effectors to facilitate host colonisation, including evolutionarily conserved ...
