This weeks GARNet research roundup begins with a microscopy-based study led by Lorenzo Frigerio from the University of Warwick that investigates the origin of Protein Storage Vacuoles. The second paper from John Doonan at Aberystwyth University looks at how differential splicing of cyclin-dependent Kinase G1 effects the thermosensory response. Reiner van de Hoorn from Oxford[…]
This edition of the GARNet research roundup begins with an analysis of the CELLULOSE SYNTHASE COMPLEX led by Simon Turner in Manchester. Next are two papers from Ian Henderson at Cambridge who, in collaboration with Rob Martienssen in the USA, has investigated the epigenetic factors that control meiotic recombination. Next are two papers led by[…]
This Arabidopsis Research Roundup has five papers that includes two from the John Innes Centre and two from the University of Edinburgh. Firstly Kristen Bomblies’s group at the JIC have investigated the relationship between temperature and meiotic recombination rates. Secondly Veronica Grieneisen and Stan Maree have developed a mathematical model to characterise cell morphologies taken[…]
The first two papers in this weeks Arabidopsis Research Roundup investigate different aspects of the plants response to temperature fluctuations. Firstly Lars Ostergaard (JIC) looks at the influence of temperature in the control of fruit dehiscence whilst Phil Wigge (SLCU) investigates crosstalk between chloroplast and nuclear signaling. The third paper from Ian Henderson (University of[…]

This edition of the Arabidopsis Research roundup beings with a study from SLCU that provides a molecular context to the changes that occur at graft junctions. Second is a study from Edinburgh that reports on the findings of a citizen science plant phenotyping project. Third are two studies from the John Innes Centre that follow-on[…]
This weeks Arabidopsis Research Roundup begins with a study from SLCU that investigates the interaction between nitrate and cytokinin signaling in the shoot meristem. Next is research from Sheffield that studies changes to the macromolecular composition of the photosynthetic apparatus following the transition from dark to light. Third are three papers that include University of[…]
GARNet with support from the Bristol Centre for Agricultural Innovation and New Phytologist are organising a Gene Editing Workshop that will take place at the University of Bristol on March 26th-27th 2018. This workshop is designed to encourage interactions and discussion about the use of CRISPR-Cas9 gene editing in plant systems. We are encouraging ECRs[…]
Henrik Jonsson and Benoit Landrien discuss their new PNAS paper entitled ‘Nitrate modulates stem cell dynamics in Arabidopsis shoot meristems through cytokinins‘.

The cellular mechanics of auxin perception and signaling have been well studied over the past two decades. The pivotal interaction that controls this activity involves the auxin-dependent contact between the TIR1 receptor and a family of transcriptional regulators called AuxIAA proteins. This interaction has been characterised at a structural level with the auxin indole-3-acetic acid[…]
