Uneven hormone distribution in plants regulates cell division and growth, biologists discover
New research from an international team of plant biologists, led by researchers at the VIB-UGent Center for Plant Systems Biology, has revealed crucial insights into the role brassinosteroids—essential plant hormones—play in regulating cell division and growth. The findings, published in Cell, provide a comprehensive understanding of how these hormones influence development at the cellular level.
Scientists uncover mechanism preserving centromere during cell division
Scientists have solved a decade-long question about the mechanism that preserves the centromere, the hub that ensures DNA divides correctly during cell division.
Single nucleosomes tracked in live cells during cell division using super-resolution microscopy
Individual cells divide through a process called mitosis, during which the cell's copied DNA is separated between two resulting daughter cells. Despite recent advances in cell biology, the mechanism by which DNA condenses during mitosis is still poorly understood. Researchers recently tracked small stretches of DNA wound around histone proteins, called nucleosomes, to better characterize nucleosome behavior during cell division.
Unique characteristics of previously unexplored protein discovered
An international research collaboration has uncovered a new mechanism of the crosstalk between microtubules and actin cytoskeleton during cell division and revealed unique characteristics of the previously unexplored protein FAM110A.
Secrets of cell division revealed by cutting-edge imaging technique
A study by Fena Ochs, new Group Leader and Associate Professor at Biotech Research & Innovation Center (BRIC) University of Copenhagen, delves deep into the intricate world of cell division. The study, published in Science, sheds light on the role of cohesin, which is a crucial protein complex that helps to faithfully segregate genetic material during cell division.
How does a bacterium know it's time to split apart?
Bacterial cells do not wake up one morning and decide to become parents. But there is a point in their cell cycle—after growing sufficiently and replicating their genomes—when they split in two, creating new cells that then repeat the process. What tells the bacterium that it's time to split apart? Scientists have been divided on the subject.
From growing roots, clues to how stem cells decide their fate
It might look like a comet or a shooting star, but this time-lapse video is actually a tiny plant root, not much thicker than a human hair, magnified hundreds of times as it grows under the microscope.
Protein CENP-E plays important role during cell division
Cells divide to produce new cells. A protein meshwork called the fibrous corona plays an important role during this process, as it ensures that DNA is evenly distributed over the new daughter cells. In collaboration with the UMC Utrecht, researchers from the group of Geert Kops now offer new insight into the components that are involved in the formation of the fibrous corona and found a key role for the protein CENP-E. They published their results in the Journal of Cell Biology on November 7th.
