Plasmodesmata channels connect neighbouring plant cells and respond to external stimuli via changes in permeability. Here Park et al. propose that mechanical forces can displace the dumbbell-shaped ER-desmotubule complex that spans the central plasmo

Light microscopy is the standard tool for studying sub-cellular structures however, owing to the diffractive properties of light, resolution is limited to 200 nm. Super-resolution microscopy methods circumvent this limit, offering greater resolution,

Sucrose is the main saccharide used for long‐distance transport in plants and plays an essential role in energy metabolism; however, there are no analogues for real‐time imaging in live cells. We have optimised a synthetic approach to prepare suc

The study of phloem transport and its vital roles in long-distance communication and carbon allocation have been hampered by a lack of suitable tools that allow high-throughput, real-time studies. Esculin, a fluorescent coumarin glucoside, is recogni

Sieve elements (SEs) degrade selected organelles and cytoplasmic structures when they differentiate. According to classical investigations, only smooth ER, mitochondria, sieve element plastids, and, in most cases, P-proteins remain in mature SEs. Mor

This review focuses on the recent development of a suite of fluorescent probes that can be used to trace phloem-transport rates in a range of diverse species. Some of these probes are loaded into the phloem by virtue of optimal physico-chemical prope

In plants, plasmodesmata (PD) are nanopores that serve as channels for molecular cell-to-cell transport. Precise control of PD permeability is essential to regulate processes such as growth and tissue patterning, photoassimilate distribution and defe

Using Arabidopsis (Arabidopsis thaliana) seedlings, we identified a range of small fluorescent probes that entered the translocation stream and were unloaded at the root tip. These probes had absorbance/emission maxima ranging from 367/454 to 546/576
