Correlation between cell size and cell nuclei size in plant stem cells

The Jönsson group previously showed a correlation between cell size and cell nuclei size in plant stem cells - Top left: shoot stem cells where the membranes are marked in red and nuclei are marked in green. Top right: plot showing the size relation between cells and cell nuclei in the stem cell region [modified from Willis et al PNAS (2016)]. In this project an interdisciplinary approach will be used to investigate the connection between cell shapes, nuclear deformations and genetic activity – Bottom right: a cell removed from the tissue can be used for biophysical perturbations, microtubules are marked in green and the nuclei in purple (Formosa-Jordan, Wang, Jönsson, unpublished). Bottom right: mechanical stress patterns predicted during the initial outgrowth of a root hair from a finite element model simulation [from Krupinski et al Front Plant Sci (2016)]. A challenge of the project will be to integrate this type of model to include an effect on cell nuclei.

Harnessing tomato jumping genes could help speed-breed drought-resistant crops

Sep 16, 2019

Once dismissed as ‘junk DNA’ that served no purpose, a family of ‘jumping genes’ found in tomatoes has the potential to accelerate crop breeding for traits such as improved drought resistance.

Food of the Future: free online course launched to inspire the next generation of scientists

Aug 30, 2019

A new, free online course aimed at 16-19 year olds across Europe, funded by EIT Food and developed by the Gatsby Plant Science Education Programme (GPSEP) at the University of Cambridge alongside international partners, aims to inspire young people to study science so they can help to create food of the future.

How plants coordinate their biological clocks

Aug 15, 2019

New research from James Locke's group shows that clocks in plant seedlings can self-organise without a master.
