Impacts of climate change on the first occurrence of the Light blight (Phytophthora infestans (Mont.) de Bary 1876)

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
The increase in the infestation pressure of various pathogens will be one the most important factors limiting the crop production under the future climate conditions.

Divergent Evolution of PcF/SCR74 Effectors in Oomycetes Is Associated with Distinct Recognition Patterns in Solanaceous Plants

mBio, 2020
Plants deploy cell surface receptors known as pattern-recognition receptors (PRRs) that recognize non-self molecules from pathogens and microbes to defend against invaders.

Rhizobacteria‐Induced Systemic Priming Against Fungal Pathogens Involves Hydroxycinnamic Acid Amides

Plant, Cell &Environment, EarlyView.
ABSTRACT The rhizosphere, a narrow region of soil surrounding roots, contains diverse microorganisms with a composition that is distinct from the surrounding soil. Some rhizosphere bacteria can trigger a heightened state of immunity in the whole plant, termed Induced Systemic Resistance (ISR).

Mutations in the EDR1 Gene Alter the Response of Arabidopsis thaliana to Phytophthora infestans and the Bacterial PAMPs flg22 and elf18

Molecular Plant-Microbe Interactions, 2015
Mechanistically, nonhost resistance of Arabidopsis thaliana against the oomycete Phytophthora infestans is not well understood. Besides PEN2 and PEN3, which contribute to penetration resistance, no further components have been identified so far.

Phytophthora infestans has a plethora of phospholipase D enzymes including a subclass that has extracellular activity. [PDF]

PLoS ONE, 2011
In eukaryotes phospholipase D (PLD) is involved in many cellular processes. Currently little is known about PLDs in oomycetes. Here we report that the oomycete plant pathogen Phytophthora infestans has a large repertoire of PLDs divided over six ...

A Non‐Host Pathogen Elicitor Induces Blast Resistance Mediated by OsNAC78‐Pir7b Module in Rice

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants exhibit broad‐spectrum and persistent resistance induced by non‐host pathogens. Previous studies have found that syringolin A secreted by Pseudomonas syringae pv. syringae can activate the expression of defense‐related gene Pir7b in non‐host rice, but the underlying mechanism remains ambiguous.

Shigella Effector VirA Suppresses Plant Immunity by Compromising PRA1.F3‐Dependent Accumulation of FLS2 at the Plasma Membrane

Plant, Cell &Environment, EarlyView.
ABSTRACT Surface immune receptors such as flagellin‐sensitive 2 (FLS2) are critical for plant defence, and their accumulation at the plasma membrane is tightly controlled by the endomembrane system. Here, we identify the Arabidopsis thaliana prenylated Rab acceptor PRA1.F3 as a positive regulator required for efficient accumulation of FLS2 at the ...

Complete Mitochondrial Genome of Phytophthora nicotianae and Identification of Molecular Markers for the Oomycetes

Frontiers in Microbiology, 2017
Phytophthora nicotianae is one of the most destructive plant pathogens affecting a variety of plants, causing black shank of tobacco, among several other devastating diseases. Herein, we assembled the mitochondrial genome of P.

Predicting Daily Aerobiological Risk Level of Potato Late Blight Using C5.0 and Random Forest Algorithms under Field Conditions

Sensors, 2023
Late blight, caused by Phytophthora infestans, is a major disease of the potato crop with a strong negative impact on tuber yield and tuber quality. The control of late blight in conventional potato production systems is often through weekly application ...

Survival of Phytophthora infestans in Surface Water [PDF]

Phytopathology®, 2004
Coverless petri dishes with water suspensions of sporangia and zoospores of Phytophthora infestans were embedded in sandy soil in eastern Washington in July and October 2001 and July 2002 to quantify longevity of spores in water under natural conditions.
