Multi-knockout of 29 phytotoxic proteins and metabolites does not completely abolish virulence of the necrotrophic fungus Botrytis cinerea

Deleting 27 CDIP-candidate genes (26 confirmed CDIPs) and two phytotoxin biosynthesis genes in Botrytis cinerea nearly abolishes apple infection but leaves slow leaf lesions, pointing to redundant, unidentified host-killing factors.

Two homologous Alt a1-like fungal proteins possess dual activities in HIR-associated immune signaling and EDS1-dependent cell death

The paper identifies Hip1 as a homolog of PEIE1, showing both immune signaling modulation and EDS1-dependent cell death induction in plants.

Gas5A, a putative glucanosyltransferase from Botrytis, functions as cell death inducing protein in plants

The paper identifies Gas5A, a glucanosyltransferase from Botrytis, as a cell death inducing protein in plants, showing it can trigger cell death both as a PAMP and intracellularly.

Multiple knockout mutants reveal a high redundancy of phytotoxic compounds that determine necrotrophic pathogenesis of Botrytis cinerea

The paper investigates the virulence of Botrytis cinerea by generating multiple knockout mutants, revealing high redundancy in phytotoxic compounds that drive necrotrophic infection.

Retrotransposons as pathogenicity factors of the plant pathogenic fungus Botrytis cinerea

This study identifies retrotransposons as pathogenicity factors in the fungus Botrytis cinerea by showing their role in enhancing aggressiveness and suppressing plant defense genes through BcsRNA production.

CRISPR/Cas with ribonucleoprotein complexes and transiently selected telomere vectors allows highly efficient marker-free and multiple genome editing in Botrytis cinerea

This paper introduces a CRISPR/Cas system using ribonucleoprotein complexes and telomere vectors for efficient marker-free genome editing in Botrytis cinerea, achieving high editing rates and enabling multiple edits.
