Effector-Mediated Spatial Reprogramming of Glycolate Oxidase Subverts Peroxisomal and Membrane-Associated ROS Defences. [PDF]

Plant Biotechnol J
ABSTRACT Oomycete pathogens secrete hundreds of RXLR effectors into plant cells to modulate host immunity by targeting diverse plant proteins. Here, we report that the Peronophythora litchii RXLR effector PlAvh133 acts as a virulence factor and targets the litchi glycolate oxidase (GLO) LcGLO1, a key enzyme in photorespiration, thereby suppressing ...

Regulation of Oomycete Autophagy, Lipid Droplet Accumulation and Pathogenesis by Three Rab GTPases. [PDF]

Mol Plant Pathol
PlRab6– PlRab8A complex controls growth, virulence and autophagy, while PlRab8B modulates sporulation and virulence via autophagy and LD metabolism in P. litchii. ABSTRACT Among eukaryotes, Rab GTPases are critical for intracellular membrane trafficking and possess various functions.

An RXLR effector PlAvh142 from Peronophythora litchii triggers plant cell death and contributes to virulence. [PDF]

Mol Plant Pathol, 2020
The RXLR effector PlAvh142 from Peronophythora litchii triggers cell death, which is dependent on plant RAR1, SGT1, and HSP90. Knockout of PlAvh142 by CRISPR/Cas9 attenuates the pathogenicity of P. litchii. Abstract Litchi downy blight, caused by the phytopathogenic oomycete Peronophythora litchii, results in tremendous economic loss in litchi ...

Pest categorisation of Pestalotiopsis disseminata

EFSA Journal, Volume 21, Issue 12, December 2023., 2023
Abstract Following the commodity risk assessments of bonsai plants from China consisting of Pinus parviflora grafted on P. thunbergii performed by EFSA, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis disseminata, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae. The pathogen has been reported on

Overexpression of Anthocyanidin Reductase Increases Flavonoids Content to Combat Fusarium Wilt in the Root Xylem of Vernicia montana. [PDF]

Mol Plant Pathol
Root xylem extract of resistant V. montana inhibited Fof‐1 growth. After Fof‐1 infection, we screened the increased 13 types of flavonoids and the up‐regulated eight genes in the flavonoid biosynthesis in V. montana. VmANR overexpression enhanced the flavonoid content, with catechin, (−)‐epicatechin and (−)‐epigallocatechin inhibiting Fof‐1 growth ...

Reasoned opinion on the joint review of maximum residue levels (MRLs) for fosetyl, disodium phosphonate and potassium phosphonates according to Articles 12 and 43 of Regulation (EC) No 396/2005

EFSA Journal, Volume 19, Issue 8, August 2021., 2021
Abstract EFSA received from the European Commission a mandate to provide its reasoned opinion on the joint review of maximum residue levels (MRLs) for fosetyl and phosphonates in or on food and feed according to Article 43 of Regulation (EC) No 396/2005.

Transcriptome analysis of Phytophthora litchii reveals pathogenicity arsenals and confirms taxonomic status. [PDF]

PLoS ONE, 2017
Litchi downy blight, caused by Peronophythora litchii, is one of the major diseases of litchi and has caused severe economic losses. P. litchii has the unique ability to produce downy mildew like sporangiophores under artificial culture. The pathogen had

6‑Pentyl‑2H‑pyran-2-one from Trichoderma erinaceum Is Fungicidal against Litchi Downy Blight Pathogen Peronophythora litchii and Preservation of Litchi

, 2023
The postharvest losses of litchi caused by litchi downy blight are considerably high. We identified a natural antifungal volatile pyrone, 6-pentyl-2H-pyran-2-one (6PP), synthesized by Trichoderma erinaceum LS019-2 and investigated as biocontrol for ...
