Ancient MAX Effector Variants of a Fungal Pathogen Evade Apoplastic Immunity in Apple

This study identifies AvrRvi6 as a fungal effector that evades Rvi6-mediated immunity in apple, revealing ancient virulence diversity in wild Malus species.

From Nicotiana to apple: effector screening reveals new avenues for durable scab resistance

The paper screens 137 fungal effector proteins for recognition by immune receptors in Nicotiana species to identify potential exogenous resistance genes for durable apple scab resistance.

PaRXLR40, a broad cell death suppressor of the kauri dieback pathogen Phytophthora agathidicida, targets a plant ARM/BTB domain-containing protein

This study identifies PaRXLR40 as a virulence factor in Phytophthora agathidicida that suppresses host immunity by targeting the ARIA protein, promoting disease susceptibility in kauri and Nicotiana benthamiana.

Molecular investigation of Rlm3 from rapeseed as a broad-spectrum resistance gene against fungal pathogens producing structurally conserved effectors

This study characterizes the Rlm3 resistance gene in rapeseed, showing it recognizes effectors from multiple fungal pathogens and identifies key regions for recognition.

Rapid breakdown of Cf-6-mediated immunity in tomato through loss or mutation of the Avr6 effector gene in Fulvia fulva

The paper identifies Avr6 as the effector gene in Fulvia fulva that overcomes Cf-6-mediated immunity in tomato, showing its loss or mutation leads to resistance breakdown.

Genomic, effector protein and culture-based analysis of Cyclaneusma minus in New Zealand provides evidence for multiple morphotypes

The paper identifies a third morphotype of Cyclaneusma minus in New Zealand through genomic and effector protein analysis, showing differences in effector family composition and function across morphotypes.

Characterization of two conserved cell death elicitor families from the Dothideomycete fungal pathogens Dothistroma septosporum and Fulvia fulva (syn. Cladosporium fulvum)

This study identifies two conserved effector families from fungal pathogens that trigger cell death in plants, showing they are recognized by immune receptors.

Phosphatidic acid produced by phospholipase D is required for hyphal cell-cell fusion and fungal-plant symbiosis

This study shows that phosphatidic acid, produced by phospholipase D, is essential for hyphal cell fusion and fungal-plant symbiosis in filamentous fungi.

Analysis of Epichloë festucae small secreted proteins in the interaction with Lolium perenne

The paper identifies and analyzes small secreted proteins from Epichloë festucae, finding they are associated with transposable elements but not essential for the mutualistic interaction with Lolium perenne.

Draft Genome Sequence of the Asian Pear Scab Pathogen, Venturia nashicola

The paper presents the first draft genome sequence of Venturia nashicola, identifying potential effector proteins that may activate non-host resistance in pear scab pathosystems.
