Phytotoxic Metabolites Produced by Legume-Associated Ascochyta and Its Related Genera in the Dothideomycetes

Toxins, 2019
Phytotoxins, secondary metabolites toxic to plants and produced by fungi, are believed to play an important role in disease development by targeting host cellular machineries and/or interfering with host immune responses. The Ascochyta blight diseases on

Genomic Surveillance of Epiphytic Pseudomonas syringae Highlights Shared Reservoirs and Cross‐Habitat Threats to Cherry Orchards and Nearby Woodland Plants

Molecular Plant Pathology, Volume 27, Issue 2, February 2026.
Highly virulent epiphytic Pseudomonas syringae PG2d strains are widespread in UK cherry orchards and woodlands, varying in abundance and threatening domestic and wild cherry health. ABSTRACT Plant surfaces host diverse microbial communities acting as reservoirs for pathogenic lineages, yet the ecological dynamics and evolutionary consequences of such ...

Fungal Phytotoxins in Sustainable Weed Management

Current Medicinal Chemistry, 2018
Fungal phytotoxins are natural secondary metabolites produced by plant pathogenic fungi during host–pathogen interactions. They have received considerable particular attention for elucidating disease etiology, and consequently to design strategies for disease control.

The sypA, sypB, and sypC Synthetase Genes Encode Twenty-Two Modules Involved in the Nonribosomal Peptide Synthesis of Syringopeptin by Pseudomonas syringae pv. syringae B301D

Molecular Plant-Microbe Interactions, 2003
Syringopeptin is a necrosis-inducing phytotoxin, composed of 22 amino acids attached to a 3-hydroxy fatty acid tail. Syringopeptin, produced by Pseudomonas syringae pv. syringae, functions as a virulence determinant in the plant-pathogen interaction.
