Nucleic acids are not only essential actors of cell life but also extremely appealing molecular objects in the development of synthetic molecules for biotechnological application, such as biosensors to report on the presence and concentration of a target ligand by emission of a measurable signal. In this work, FluorMango, a fluorogenic ribonucleic acid (RNA)‐based biosensor specific for fluoride is...
Root hairs (RHs) are tubular extensions of root epidermal cells that favour nutrient uptake and microbe interactions. RHs show a fast apical growth, constituting a unique single cell model system for analysing cellular morphodynamics. In this context, live cell imaging using microfluidics recently developed to analyze root development is appealing, although high‐resolution imaging is still lacking...
Accurate translation of genetic information necessitates the tuned expression of a large group of genes. Amongst them, controlled expression of the enzymes catalyzing the aminoacylation of tRNAs, the aminoacyl-tRNA synthetases, is essential to insure translational fidelity. In the yeast Saccharomyces cerevisiae, expression of aspartyl-tRNA synthetase (AspRS) is regulated in a process necessitating...
Structural plasticity of transfer RNA (tRNA) molecules is essential for interactions with their biological partners in aminoacylation reactions and during ribosome-dependent protein synthesis. This holds true when tRNAs are recruited for other functions than translation. Here we review regulation pathways where tRNAs and tRNA mimics play a pivotal role. We further discuss the importance of the identity...
