Silica nanoparticles enhance disease resistance in Arabidopsis plants

El-Shetehy, Mohamed ; Moradi, Aboubakr ; Maceroni, Mattia ; Reinhardt, Didier ; Petri-Fink, Alke ; Rothen-Rutishauser, Barbara ; Mauch, Felix ; Schwab, Fabienne

In: Nature Nanotechnology, 2020, p. 1–10

In plants, pathogen attack can induce an immune response known as systemic acquired resistance that protects against a broad spectrum of pathogens. In the search for safer agrochemicals, silica nanoparticles (SiO2 NPs; food additive E551) have recently been proposed as a new tool. However, initial results are controversial, and the molecular mechanisms of SiO2 NP-induced disease resistance...

Cell cycle constraints and environmental control of local DNA hypomethylation in α-proteobacteria

Ardissone, Silvia ; Redder, Peter ; Russo, Giancarlo ; Frandi, Antonio ; Fumeaux, Coralie ; Patrignani, Andrea ; Schlapbach, Ralph ; Falquet, Laurent ; Viollier, Patrick H.

In: PLOS Genetics, 2016, vol. 12, no. 12, p. e1006499

Heritable DNA methylation imprints are ubiquitous and underlie genetic variability from bacteria to humans. In microbial genomes, DNA methylation has been implicated in gene transcription, DNA replication and repair, nucleoid segregation, transposition and virulence of pathogenic strains. Despite the importance of local (hypo)methylation at specific loci, how and when these patterns are...

S-methyl methanethiosulfonate: promising late blight inhibitor or broad range toxin?

Joller, Charlotte ; Vrieze, Mout De ; Moradi, Aboubakr ; Fournier, Claudine ; Chinchilla, Delphine ; L’Haridon, Floriane ; Bruisson, Sebastien ; Weisskopf, Laure

In: Pathogens, 2020, vol. 9, no. 6, p. 496

(1) Background: S-methyl methanethiosulfonate (MMTS), a sulfur containing volatile organic compound produced by plants and bacterial species, has recently been described to be an efficient anti-oomycete agent with promising perspectives for the control of the devastating potato late blight disease caused by Phytophthora infestans. However, earlier work raised questions regarding the putative...

DNA (hydroxy)methylation in T helper lymphocytes

Monticelli, Silvia

In: Trends in biochemical sciences, 2019, vol. 44, no. 7, p. 589-598

Upon recognition of an antigen, the differentiation of antigen-inexperienced naïve T lymphocytes into subsets able to effectively coordinate host defense is controlled by a network of transcription factors and regulatory molecules. In the cell nucleus, these factors act in the context of epigenetic modifications that influence DNA accessibility and ultimately gene expression. This review...

HSP90 and co-chaperones: a multitaskers’ view on plant hormone biology

Donato, Martin di ; Geisler, Markus

In: FEBS Letters, 2019, vol. 593, no. 13, p. 1415–1430

In order to survive under ever‐changing conditions plants must be able to adaptively respond to their environment. Plant hormones and the signaling cross‐talk among them play a key role in integrating external and internal cues, enabling the plants to acclimate accordingly. HSP90 and several of its co‐chaperones are known as pleiotropic factors involved in the signaling pathways of...
