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biophysical perturbations, microtubules are marked in green and the nuclei in purple (Formosa-Jordan, Wang, Jönsson, unpublished).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.

Mix of LCOs and COs essential for mycorrhizal establishment

Nov 07, 2019

An international collaboration of scientists working to optimise arbuscular mycorrhizal associations to improve sustainability in agriculture has demonstrated new insights into how signalling pathways promote symbiotic microbial associations with plants.

Revealing the nanostructure of wood could help raise height limits for wooden skyscrapers

Oct 22, 2019

Cambridge researchers have captured the visible nanostructure of wood in its live hydrated state for the first time using an advanced low-temperature scanning electron microscope.

Network and genetic analyses reveal 32 cambium transcription factors

Oct 15, 2019

A comprehensive analysis of the transcription factors (TF) that play in the vascular cambium has boosted our understanding of the underlying transcriptional regulation in this important plant meristem through the discovery of 32 cambium TFs.
