Caleosin 1 contributes to seed lipid droplet degradation by interaction with autophagy-related protein ATG8

This study identifies caleosin 1 as a key protein involved in plant seed lipid droplet degradation through its interaction with autophagy-related protein ATG8 during germination.

Multi-omics analysis of xylem sap uncovers dynamic modulation of poplar defenses by ammonium and nitrate

This study analyzes how nitrogen supply affects xylem sap composition, endophyte growth, and leaf defenses in poplar through multi-omics approaches.

Sphingolipid-Induced Programmed Cell Death Is a Salicylic Acid and EDS1-Dependent Phenotype in Arabidopsis

This study shows that sphingolipid-induced programmed cell death in Arabidopsis depends on salicylic acid and EDS1, with LCB d18:0 accumulation being a key factor.

Ectomycorrhizal fungi induce systemic resistance against insects on a non-mycorrhizal plant in a CERK1-dependent manner

This study shows that the ectomycorrhizal fungus Laccaria bicolor induces systemic resistance against insect herbivores in Arabidopsis through a CERK1-dependent mechanism.

The cell-wall-localised BETA-XYLOSIDASE 4 contributes to immunity of Arabidopsis against Botrytis cinerea

BXL4 is a putative bifunctional xylosidase/arabinofuranosidase localising to the apoplast, important for immunity against the necrotrophic pathogen B. cinerea.

Fungal effector Jsi1 hijacks plant JA/ET signaling through Topless

This paper identifies Jsi1, a fungal effector that hijacks plant JA/ET signaling by interacting with TPL/TPR co-repressors, leading to biotrophic susceptibility.

The plastidial exporter Enhanced Disease Susceptibility 5 is required for the biosynthesis of N-hydroxy pipecolic acid

The paper shows that the exporter Enhanced Disease Susceptibility 5 is required for the biosynthesis of N-hydroxy pipecolic acid, a key compound in plant immunity.

PBS3 is the missing link in plant-specific isochorismate-derived salicylic acid biosynthesis

The paper identifies PBS3 as the enzyme that converts isochorismate to salicylic acid via isochorismate-9-glutamate in plants.

Arabidopsis mlo3 mutant plants exhibit spontaneous callose deposition and signs of early leaf senescence

This study examines Arabidopsis mlo3 mutants, finding they show spontaneous callose deposition and early senescence without pathogen challenge, suggesting a role in developmental processes rather than pathogen defense.

Pheophorbide a, a chlorophyll catabolite may regulate jasmonate signalling during dark-induced senescence in Arabidopsis

The paper shows pheophorbide a regulates jasmonate signaling during dark-induced senescence in Arabidopsis by linking chlorophyll degradation to jasmonic acid pathways.
