COST Action PlantWallK @plantwallk.org · 28/05/2026
The 1st #PlantWallK meeting brought together 80+ researchers. Cell biologists, physicists, biochemists, modellers, all converging on 1 structure: the plant cell wall. Two days of talks, posters, and cross-disciplinary debate later, the collaborations are set. The work begins! #PlantBiology #CellWall
A large group of approximately 80 researchers posing for a group photograph on the grand staircase of the Faculty of Science, Charles University, Prague. The group spans six rows, with participants standing on the steps to give height to the back rows. People are dressed in smart-casual summer attire and most wear conference lanyards in red or blue with name badges. The crowd is diverse in age, gender, and background, ranging from early-career researchers to senior scientists. Two large white neoclassical columns frame the staircase on either side. To the upper left, a dark commemorative wall plaque bearing Czech text notes that Albert Einstein held a professorship in the building between 1911 and 1912. A clock is partially visible high on the back wall. The overall atmosphere is warm and collegial.

A great way to close the #PlantWallK26 days in Prague! The EPCC satellite meeting wrapped up yesterday with a full day of scientific presentations and stimulating discussions on plant cytoskeleton. Many thanks to all contributors and participants, it was a pleasure to see the community in action.
Group photograph of EPCC satellite meeting participants, taken on 27 May 2026 in the entrance hall of a classical university building in Prague. Approximately forty attendees are arranged across several steps of a grand stone staircase, facing the camera. A small sign reading "EPCC — May 27.5.2026, Prague" is held at the front of the group.

Excited to share what we learned about Katanin in maize www.nature.com/articles/s41... 🧪

KATANIN promotes cell elongation and division to generate proper cell numbers in maize organs - Nature Communications
Here, the authors show that two genes encoding KATANIN p60 in maize promote growth and fertility via proper cell expansion and division. Aberrant microtubule organization in mutants alters cell shape,...

When stress drives you to kidnap: RACK1A sequesters FSD1 into stress granules during salt stress
Describing plants as sessile organisms may sound like a scientific revelation, but it simply means they have nowhere to go. However, it serves as a fitting
