GARNet 2014 presentations available online

As you’ll already know, we held our GARNet 2014 conference, Arabidopsis: The Ongoing Green Revolution, at the University of Bristol on the 9th and 10th September. If you didn’t know, you can read Charis’ report on it by clicking here to go to the main GARNet website, or here to see some photos!

Some of the researchers who spoke at our conference have kindly agreed to share their GARNet 2014 presentations with you online – please click the links in the programme below to view or download a PDF copy of the speaker’s slides.

Plant science, by JoVE!

JoVE 2

Researchers from the University of Warwick published a methodology paper with a twist this week. The paper, published online by the Journal of Visualized Experiments (JoVE), gives step-by-step instructions and video demonstration of a method for purifying a protein and identifying proteins that perform its post-translational modifications.

Authors Sophie Piquerez, Alexi Balmuth, Jan Skenář, Alex JonesJohn Rathjen and Vardis Ntoukakis developed the method in order to characterize the interactions between nucleotide-binding leucine-rich-repeat proteins and the Prf/Pto complex in effector-triggered immunity. In principle the method could be applied to any protein – the protein of interest is epitope-tagged, immunoprecipitated and analysed by MS.

A video journal lends itself to new or improved methodology rather than high impact conclusions. As with a lot of JoVE articles, the scientifically significant results obtained using the protocol have already been published; in this case in Ntoukakis et al. 2013 (PLOS Pathogens, 10.1371/journal.ppat.1003123).

The authors conclude the abstract by saying the paper demonstrates:

  1. Dynamic changes in PTMs such as phosphorylation can be detected by mass spectrometry;
  2. It is important to have sufficient quantities of the protein of interest, and this can compensate for the lack of purity of the immunoprecipitate;
  3. The immunoprecipitation step is essential to get enough protein to do the MS. (more…)

Warwick Systems Biology at SEB 2012

It’s time for another guest post today – Katherine Denby writes about the SEB 2012 conference.

Warwick Systems Biology Centre was well represented at the recent SEB conference in Salzburg, with 4 presentations in sessions on Biotic Stress, Environmental Control of Development and Generating New Biological Insights from Complex Data.

First up was Katherine Denby who presented analysis of a gene expression time series from Arabidopsis leaves infected with the fungal pathogen Botrytis cinerea generated in the PRESTA project. Using a variety of network inference algorithms, the group has generated models of the gene regulatory networks underlying the Arabidopsis response to this pathogen. These network models have highlighted specific regulatory interactions, and led to identification of transcription factors with a novel role in defence. Modelling using gene expression time series from other biotic and abiotic stresses has predicted a core regulatory network underlying multiple stress responses with differential flux through the network under different environmental conditions. Katherine also described a novel tool, Wigwams, to identify groups of genes significantly co-expressed across multiple stresses. Integrating this with the network models enables prediction of the upstream regulators of these groups. (more…)
