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 ...

Live cell imaging of asymmetric cell division in fertilized plant cells Insight into why leaves grow up and roots grow down in flowering plants Date: November 29, 2016 Source: Institute of ...

Mean cell size at division is generally constant for specific conditions and cell types, but the mechanisms coupling cell growth and cell cycle control with cell size regulation are poorly ...

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 ...

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 ...

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 ...

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 ...

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.

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 ...

“We found that the shifts in cell morphology that shape tissues could…trigger asymmetric division and direct core identity decisions underpinning tissue building.” If the asymmetry leads to ...

For a new plant to grow from a seed, cells need to divide numerous times. Daughter cells can each take on different tasks and sometimes vary in size. How plants determine the plane of cell division in ...
