In plant cells, the division plane is predicted before mitosis by the location of a preprophase (PPB) band of microtubules and actin filaments in the cell cortex. The phragmoplast, a cytoskeletal ...

When the stem of a plant is injured, the surrounding cells ... However, image analysis revealed abnormal cell division in at2-mmp mutants. Conversely, when At2-MMP was overexpressed, normal ...

Research undertaken on two distantly related plant species at the Sainsbury Laboratory Cambridge University (SLCU) provides new evidence suggesting local level cell division has an active role to ...

Inside the root, plant cells are under high pressure ... the microtubules reposition themselves and establish the orientation of cell division, which triggers it. "Our results suggest that ...

What can soap bubbles tell us about cell division? More than you might think: in 1886 Leo Errera noted that bubbles in soap resembled dividing cells. He thought the shape of the bubbles could predict ...

A new study challenges a widely-held notion about cell division. © screenshot from a video by The University of Manchester, with photo editing by Gizmodo If you took ...

Plant cells are surrounded by an intricately structured protective coat called the cell wall. It’s built of cellulose microfibrils intertwined with polysaccharides like hemicellulose or pectin.

Moreover, we found that these plant proteins are concentrated at plasmodesmata." The team's research revealed that plasmodesmata bridges form through an incomplete process of cell division.

The team discovered a crucial role played by the plant hormone auxin in activating cell division. “A key finding, and the biggest surprise to us, was that protoplasts need to make new auxin to ...
