Abstract. Determining elemental concentrations in plant tissues is essential for physiological studies on abiotic stress. However, high-throughput routine

Aims In harsh environments such as Alpine screes, the substrate represents one of the main selective constraints for plants. The substrate’s influence on species distributions has been well characteri...

Des tribunes sortent en ce moment dans la presse pour dénoncer les coupes dans les budgets de la recherche et le décrochage scientifique de la France. La situation est grave ; elle est l’aboutissemen…

Le nickel est un métal essentiel pour les plantes. Il est le cofacteur indispensable à uréase, qui dégrade l’urée pour recycler l’azote. Cependant, le nickel est toxique quand il est présent en excès,...

Nature Protocols, Published online: 11 March 2026; doi:10.1038/s41596-026-01337-xThis protocol details the quantitative imaging of apoplastic pH in Arabidopsis thaliana roots using confocal microscopy combined with the fluorescent pH probe 8-hydroxy-pyrene-1,3,6-trisulfonic acid trisodium salt, enabling apoplastic pH dynamics to be assessed with high spatial resolution and accuracy.

A comprehensive single-nucleus transcriptomic atlas of Arabidopsis across multiple tissues enables the quantification of leaf cell aging state at a single-cell level, highlighting the senescence-relat...

Manganese (Mn) toxicity in acidic or waterlogged soils severely impacts crop productivity. Although high-Mn stress triggers Ca2+ signals that regul...

Le bacille de la tuberculose survit dans les cellules immunitaires en neutralisant des métaux toxiques comme le zinc.

The world faces energy shortages as fossil fuels are phased out. Research can’t go on as normal.

This study reports the identification of a transposon insertion in the 5' UTR of OsPT1, which enables its cadmium (Cd)-induced transcriptional activation by the transcription factor OsbHLH35, thereby ...

Tan and colleagues develop DNA nanodevices to detect the pH of the lysosomal outer surface, observing an acidic layer generated by TMEM175 that regulates lysosome positioning in response to changes in...

The new directive asks workers to check the backgrounds of foreign nationals collaborating with the department’s scientists for evidence of “subversive or criminal activity.” Their names are being sen...

Un groupe d’activistes anonymes s’emploie depuis près d’un an à suivre, voire à menacer juridiquement, les détectives de l’intégrité scientifique. Chroniques d’une guerre invisible.

Symbioses have been fundamental to colonization of terrestrial ecosystems by plants and their evolution. Emergence of the ancient arbuscular mycorrhizal symbiosis was followed by the diversification o...
