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 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.
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
