SALICYLIC ACID SENSOR1 reveals the propagation of an SA hormone surge during plant pathogen advance Open
Salicylic acid (SA) is a key phytohormone that orchestrates immune responses against pathogens, including Pseudomonas syringae bacteria. The timing and extent of SA accumulation are tightly controlled by plants but can be suppressed by pat…

A resilient bunch: stem cell antiviral immunity in plants Open
Summary Stem cells are vital for plant development and reproduction. The stem cells within shoot apical meristems are known to possess exceptionally effective antiviral defenses against pathogenic viruses which preclude their infection, ye…

Cauliflower mosaic virus disease spectrum uncovers novel susceptibility factor<i>NCED9</i>in<i>Arabidopsis thaliana</i> Open
Viruses are intimately linked with their hosts and especially dependent on gene-for-gene interactions to establish successful infections. On the host side, defence mechanisms such as tolerance and resistance can occur within the same speci…

<i>Cauliflower mosaic virus</i>disease spectrum uncovers novel susceptibility factor NCED9 in<i>Arabidopsis thaliana</i> Open
Viruses are intimately linked with their hosts and especially dependent on gene-for-gene interactions to establish successful infections. The genotype of their hosts thus has a strong influence on the outcome virus disease. On the host sid…

<i>Cauliflower mosaic virus</i>protein P6 forms a microenvironment for RNA granule proteins and interferes with stress granule responses Open
Biomolecular condensation is a multipurpose cellular process that viruses use ubiquitously in their multiplication. CaMV replication complexes are condensates that differ from most viruses in being non-membranous assemblies and consist of …

Arabidopsis RNA processing body components LSM1 and DCP5 aid in the evasion of translational repression during <i>Cauliflower mosaic virus</i> infection Open
Viral infections impose extraordinary RNA stress, triggering cellular RNA surveillance pathways such as RNA decapping, nonsense-mediated decay, and RNA silencing. Viruses need to maneuver among these pathways to establish infection and suc…

Salicylic acid and the viral virulence factor 2b regulate the divergent roles of autophagy during cucumber mosaic virus infection Open
Macroautophagy/autophagy is a conserved intracellular degradation pathway that has recently emerged as an integral part of plant responses to virus infection. The known mechanisms of autophagy range from the selective degradation of viral …

Turnip crinkle virus targets host ATG8 proteins to attenuate antiviral autophagy Open
SUMMARY Autophagy has emerged as a central player in plant virus disease and resistance. In this study we have addressed the potential roles of autophagy in Turnip crinkle virus (TCV) infection. We found that autophagy attenuates disease s…
