Observing the invisible: X‐ray CT for plant–microbe interactions

New Phytologist, Volume 251, Issue 3, Page 959-966, August 2026.
Utility of X‐ray computed tomography (X‐ray CT) for visualising belowground plant interactions between multiple spatial scales and focal planes. Summary Plant–microbe interactions are inherently spatial, yet the physical structure of the soil and rhizosphere is rarely treated as a mechanistic variable in experimental design.

Minimal ATP‐Independent N2‐Reducing Systems Defined by L‐Cluster‐Bound Nitrogenase Assembly Platforms

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Association of the L‐cluster with the nitrogenase assembly proteins NifEN (NifENL) or NifB (NifBL) intrinsically endows these proteins with N2‐reducing activity, enabling in vitro N2‐reduction by NifENL and NifBL when supplied with chemical reductants or photoexcited quantum dots while supporting in vivo N2‐fixation in NifENL‐ and NifENL‐expressing ...

Simultaneous Visualization of Enzymatic Activity in the Cytoplasm and at Polyphosphate Inclusions in Beggiatoa sp. Strain 35Flor Incubated with ¹⁸O-Labeled Water

mSphere, 2018
Here we report on a new nanoscale secondary ion mass spectrometry (nanoSIMS) approach based on enzyme-mediated oxygen isotope exchange, which combines the visualization of general metabolic activity in the cytoplasm with insights into the activity of ...

NanoSIMS Reveals New Structural and Elemental Signatures of Early Life

, 2006
The young technology of NanoSIMS is unlocking new information from organic matter in ancient sediments. We have used this technique to characterize sub-micron scale element composition of Proterozoic organics that are clearly biogenic as a guide for ...

Carbon assimilation and accumulation of cyanophycin during the development of dormant cells (akinetes) in the cyanobacterium Aphanizomenon ovalisporum

Frontiers in Microbiology, 2015
Akinetes are spore-like non-motile cells that differentiate from vegetative cells of filamentous cyanobacteria from the order Nostocales. They play a key role in the survival and distribution of these species and contribute to their perennial blooms ...

NanoSIMS applied to the study of foraminifera [PDF]

, 2016
NanoSIMS (Nanoscale Secondary-Ion Mass Spectrometry) is a powerful analytical technique that allows quantitative, subcellular imaging of incorporation and transfer of isotopically labeled compounds and metabolites in biological tissue (Hoppe et al., 2013)

Depth Correction of 3D NanoSIMS Images Shows Intracellular Lipid and Cholesterol Distributions while Capturing the Effects of Differential Sputter Rate

, 2022
Knowledge of the distributions of drugs, metabolites, and drug carriers within cells is a prerequisite for the development of effective disease treatments. Intracellular component distribution may be imaged with high sensitivity and spatial resolution by

A NanoSIMS Investigation on Timescales Recorded in Volcanic Quartz From the Silicic Chon Aike Province (Patagonia)

Frontiers in Earth Science, 2018
Textural and chemical differences in coeval rhyolitic effusive and explosive eruptions are commonly observed, and numerical models predict different timescales for the eruption of crystal-rich mushes versus crystal-poor magmas. We compare quartz zonation

Look@NanoSIMS - a tool for the analysis of nanoSIMS data in environmental microbiology

, 2012
We describe an open‐source freeware programme for high throughput analysis of nanoSIMS (nanometre‐scale secondary ion mass spectrometry) data. The programme implements basic data processing and analytical functions, including display and drift‐corrected ...
