Arabidopsis thaliana transformed with the GFP calcium biosensor GCaMP3 allow for the real-time in vivo imaging of calcium dynamics with a high temporal and spatial resolution. Genetics Purification of High Molecular Weight Genomic DNA from Powdery Mildew for Long-Read Sequencing Joanna M. Feehan*1,2, Katherine E.

Biology Identification of Post-translational Modifications of Plant Protein Complexes Sophie J. M. Piquerez1, Alexi L. Balmuth2, Jan Sklenář2, Alexandra M.E. Jones1,2, John P. Rathjen3, Vardis Ntoukakis1 1School of Life Sciences, University of Warwick, 2The Sainsbury Laboratory, Norwich Research Park, 3Research School of Biology, The Australian National University We describe here a protocol for the purification and characterization of plant protein complexes. We demonstrate that by immunoprecipitating a single protein within a complex, so we can identify its post-translational modifications and its interacting partners.
