Cyanophora paradoxa mitochondrial tRNAs play a double game
Despite their monophyletic origin, mitochondrial (mt) genomes developed independently in evolutionarily divergent organisms, leading to a fascinating complexity…
mRNA uridylation prevents the production of deleterious siRNAs
Plants can fight viruses by synthesizing small interfering RNAs (siRNAs) that target and destroy viral RNAs. Yet, plants’…
A plant enzyme hijacked to fight viruses
Plant viruses are responsible for huge crop yield losses worldwide. The team of Philippe Giegé has developed a…
A eukaryotic protein at the heart of the synthesis of the chloroplast ribosome!
The chloroplast is an organelle in plant cells that originated from the ancient endosymbiosis of a cyanobacterium and…
Diverting flower scent metabolism for herbicides resistance
Metabolism-dependent herbicide resistance of invasive weeds is currently a major threat for intensive agriculture. Metabolism frequently leads to…
Plant-virus crosstalk at the infection front
Little is known about the molecular dialogue between the plant and an invading virus.
How to visualize mRNA in vivo
Manfred Heinlein and Eduardo Peña at the University of La Plata (Argentina) developed a novel method to observe…
Reticulon‐like properties of a plant virus movement protein
Plant viruses encode movement proteins (MPs) that ensure the transport of viral genomes through plasmodesmata (PD) and use…
Epigenetic silencing of clustered tRNA genes in Arabidopsis
Transfer RNAs (tRNAs) play a key role in the translation and reading of the genetic code. Therefore, the…
Phthalate exposure and dementia: is there a link?
The involvement of micropollutants in the development of neurodegenerative diseases is increasingly considered. Thanks to a metabolomic study,…
A new function of the FBL17 cell cycle regulator in the response to DNA damage in Arabidopsis
So-called genotoxic stresses (UV, viral infections, chemical agents) can induce DNA damage such as breaks in the DNA…
Covidog, using the flair of dogs to detect Covid-19
Three Strasbourg researchers have combined their expertise for the Covidog project. Their idea? Isolate the smell of Covid-19…
Defended fortresses or moving targets
Two 30-year-old theories aim at describing the ecology of plant defenses to insects. Emmanuel Gaquerel and collaborators at…
To be, or not to be, remethylated
The characterization of the critical features of remethylable and non-remethylable loci shed light on the epigenetic determinants allowing…
When structural biology makes it possible to visualize how a Nanobody neutralizes a plant virus!
Scientists determined the atomic structure by cryo-electron microscopy of a complex between the Grapevine fanleaf virus (GFLV), a…
Impairing degradation can rescue miRNA production
SERRATE is a conserved RNA effector protein involved in transcription, processing and export of different types of RNAs.…
DNA binding proteins regulate gene transcription but not only!
When we think about the functions of DNA binding proteins, the regulation of genome replication or gene transcription…
When the shape of the nucleus communicates stress in plants!
Plants have developed many strategies to adapt to their environment. In an interdisciplinary study, the teams of
The plant mitochondrial ribosome: an “augmented” bacterial ribosome
Translation, the essential process that decodes messenger RNA into protein, is carried out by ribosomes. The team of…
CUL3 BPM E3 ubiquitin ligases regulate MYC2, MYC3, and MYC4 stability and JA responses
Jasmonates (JAs) are essential phytohormones that regulate many developmental and defensive responses in plants. The transcription factors MYC2,…
When the roots speak to the leaves !
In plants, roots and leaves communicate to ensure optimal growth of the plant according to environmental changes. Patrick…
The hidden face of floral scents: ward off insects and modulate the microbiome
The flowers of the model plant Arabidopsis emit little perfume. They convert volatile terpenes into oxygenated derivatives that…
P0, a suicidal protein sacrificed by the virus!
In plants, RNAi is one of the major defense mechanisms against viruses. At the heart of this machinery,…
Naturally transgenic plant species occur on an unexpectedly large scale.
Agrobacterium is well-known as a vector for transferring genes to plants. In nature, this bacterium infects plants, and…
