Fungus Derived Indole‐3‐Acetic Acid Controls Developmental Conidial Death in Magnaporthe oryzae

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.
The severity of rice blast disease, caused by the fungus Magnaporthe oryzae, is influenced by IAA concentration and cell density. IAA regulates ferroptotic death of the developing conidia by affecting iron and lipid homeostasis. ABSTRACT Ferroptotic death of the developing conidia is important for pathogenicity of the blast fungus Magnaporthe oryzae ...

A Pangenome Framework Reveals Conserved Pathogenicity‐Associated Biosynthetic Gene Clusters in Fusarium equiseti, a Root Rot Pathogen of Panax notoginseng

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.
Integrating pangenome and infection‐stage transcriptome analyses with CRISPR/Cas9 genetics identifies conserved secondary metabolite biosynthetic gene clusters, including an ICS–NRPS and a siderophore pathway, as key determinants of Fusarium equiseti P26 pathogenicity on Panax notoginseng.

Pan2‐Pan3 Complex‐Mediated Deadenylation Enforces mRNA Quality Control for Infection of the Rice Blast Fungus

Advanced Science, Volume 13, Issue 18, 27 March 2026.
Discovery that deadenylation, rather than transcription, acts as the rate‐limiting step for developmental timing in a plant pathogen. Evidence that P‐body integrity and mRNA decay are mechanistically coupled to rapid cellular differentiation under environmental stress. Identification of Pan2‐Pan3 as a pathogen‐specific “meta‐virulence factor” absent in

bZIP63.5 Regulates a Zinc‐Finger Mediated Detoxification Network in Trichoderma Harzianum for Enhanced Biocontrol of Alternaria alternata

Microbial Biotechnology, Volume 19, Issue 3, March 2026.
The bZIP63.5 transcription factor, activated by Alternaria alternata stress, directly upregulates zinc‐finger transcription factors (Zn2CyS6 and C2H2 types), which in turn enhance the expression of downstream detoxification and defence‐related genes, collectively improving the biocontrol efficacy of Trichoderma harzianum.

Stagonosporopsis cucurbitacearum Effector Protein ScAA9 Contributes to Virulence and Triggers Plant Immune Responses

Molecular Plant Pathology, Volume 27, Issue 3, March 2026.
The AA9 family protein ScAA9 of Stagonosporopsis cucurbitacearum plays dual roles as both a virulence factor for infection and a PAMP for host immune manipulation, highlighting the complexity of S. cucurbitacearum–host interactions. ABSTRACT Fungal pathogens secrete cell wall‐degrading enzymes that either act as virulence factors or are perceived by ...
