Sequential breakdown of the complex Cf-9 leaf mould resistance locus in tomato by Fulvia fulva

This study identifies Avr9B, an effector that allows F. fulva to overcome Cf-9B resistance in tomato, showing sequential breakdown of the Cf-9 locus.

Cell wall carbohydrate dynamics during the differentiation of infection structures by the apple scab fungus, Venturia inaequalis

This study investigates cell wall carbohydrate dynamics in Venturia inaequalis during infection structure differentiation, revealing down-regulation of immunogenic carbohydrate biosynthesis genes and chitosan coating of infection structures.

The Venturia inaequalis effector repertoire is expressed in waves and is dominated by expanded families with predicted structural similarity to avirulence proteins from other plant-pathogenic fungi

The paper characterizes the temporal expression of effector candidates in Venturia inaequalis during apple infection and identifies structural similarities to avirulence proteins from other fungi.

CRISPR-Cas9 gene editing and rapid detection of gene-edited mutants using high-resolution melting in the apple scab fungus, Venturia inaequalis

Effector loss drives adaptation of Pseudomonas syringae pv. actinidiae to Actinidia arguta

This study identifies effector loss in Pseudomonas syringae pv. actinidiae as a driver of adaptation to Actinidia arguta, revealing key effectors involved in host resistance.

Apoplastic effector candidates of a foliar forest pathogen trigger cell death in host and non-host plants

The paper identifies apoplastic effector candidates from Dothistroma septosporum that trigger cell death in both host and non-host plants, suggesting their recognition by immune receptors.

A new family of structurally conserved fungal effectors displays epistatic interactions with plant resistance proteins

The paper identifies a new family of fungal effectors, LARS, that structurally resemble known avirulence effectors and can trigger or suppress plant resistance.

A homologue of the mammalian tumour suppressor protein PTEN is a functional lipid phosphatase and required for chemotaxis in filamentous fungi

This study identifies TepA, a fungal homologue of PTEN, as a functional lipid phosphatase required for chemotaxis in filamentous fungi.

Variation at the common polysaccharide antigen locus drives lipopolysaccharide diversity within the P. syringae species complex

The paper identifies a genetic locus driving LPS diversity in P. syringae by analyzing allelic variation in the TET operon and its impact on LPS structure and immunogenicity.

Reprogramming of the apoplast metabolome of Lolium perenne upon infection with the mutualistic symbiont Epichloë festucae

The paper investigates changes in the apoplast metabolome of Lolium perenne infected with Epichloë festucae, identifying novel metabolites and validating methods for their detection.

Specific hypersensitive response-associated recognition of new apoplastic effectors from Cladosporium fulvum in wild tomato

The paper identifies new Cf genes in wild tomato by screening for hypersensitive response recognition of Cladosporium fulvum effectors.
