  • Introduction
    Frank Van Breusegem Admin Oxidative Stress Signalling Frank Van Breusegem Introduction Suboptimal growth conditions caused by drought temperature salt and pathogen related stresses are leading to worldwide yield losses in cultivated crops It is anticipated that these issues become even bigger in the future as climatic changes will cause more temperature and drought stress and in the meantime the demand for plants for food feed and bioenergy is increasing Obviously this encouraged the search and development of appropriate breeding strategies and has made crop stress tolerance a major objective in plant biotechnology research Next Projects Frank Van Breusegem Group Members Lab Members and Alumni Publications Frank Van Breusegem Research Groups Alain Goossens Lab Ann Depicker Lab Bruno Cammue Lab Daniel Van Damme Lab Dirk Inzé Lab Frank Van Breusegem Lab Geert De Jaeger Lab Ive De Smet Lab Jenny Russinova Lab Lieven De Veylder Lab Mieke Van Lijsebettens Lab Moritz Nowack Lab Sofie Goormachtig Lab Steven Maere Lab Tom Beeckman Lab Yves Van de Peer Lab Wout Boerjan Lab About PSB PSB Missions The Department Infrastructure Core Facilities International Projects Publications News Seminars Research Groups Alain Goossens Lab Ann Depicker Lab Bruno Cammue Lab Daniel Van Damme Lab Dirk Inzé

    et al 2004 The type II metacaspase AtMC9 has been thoroughly characterized in our lab during the last ten years It has rather different characteristics than the other investigated metacaspases having an acidic pH optimum and no requirement for calcium whereas other metacaspases typically have neutral pH optima and a strict calcium requirement for activity A screening of a combinatorial tetrapeptide library of approximately 130 321 substrates with AtMC9 indicated the tetrapeptide Val Arg Pro Arg VRPR as the optimized substrate AtMC9 activity is regulated by a serine protease inhibitor AtSerpin1 by covalently binding to AtMC9 and S nitrosylation of the active site cysteine Belenghi et al 2007 Vercammen et al 2006 Degradome studies by the COFRADIC technology have revealed a potential developmental function of AtMC9 during early seedling development where the activity of phosphoenolpyruvate carboxykinase 1 PEPCK1 a key enzyme in gluconeogenesis is enhanced upon MC9 dependent proteolysis Tsiatsiani et al 2013 These and other roles of type II metacaspases are being investigated with the help of degradome studies The type I metacaspases AtMC1 and AtMC2 control hypersensitive type cell death upon pathogen attack Coll et al 2010 In a collaborative effort with the group of Jeff Dangl University of North Carolina at Chapel Hill USA we demonstrated that AtMC1 positively drives cell death in the highly localized patches of cell death that are typical to the rapid response to pathogens called the hypersensitive response Interestingly AtMC2 antagonizes this action and therefore is a negative regulator of cell death We further investigate the intriguing spatiotemporal regulation of AtMC1 and AtMC2 during hypersensitive response as well as upstream and downstream actors degradome of the pathway Further reading Stael S Kmiecik P Willems P Van Der Kelen K Coll N S Teige M and Van Breusegem F 2015 Plant innate immunity sunny side up Trends Plant Sci 20 3 11 Wrzaczek M Vainonen J P Stael S Tsiatsiani L Help Rinta Rahko H Gauthier A Kaufholdt D Bollhöner B Lamminmäki A Staes A Gevaert K Tuominen H Van Breusegem F Helariutta Y and Kangasjärvi J 2015 GRIM REAPER peptide binds to receptor kinase PRK5 to trigger cell death in Arabidopsis EMBO J 34 55 66 Bollhöner B Zhang B Stael S Denancé N Overmyer K Goffner D Van Breusegem F and Tuominen H 2013 Post mortem function of AtMC9 in xylem vessel elements New Phytol 200 498 510 Tsiatsiani L Timmerman E De Bock P J Vercammen D Stael S van de Cotte B Staes A Goethals M Beunens T Van Damme P Gevaert K and Van Breusegem F 2013 The Arabidopsis METACASPASE9 degradome Plant Cell 25 2831 2847 Tsiatsiani L Gevaert K and Van Breusegem F 2012 Natural substrates of plant proteases how can protease degradomics extend our knowledge Physiol plant 145 28 40 Turk B Turk D and Turk V 2012 Protease signalling the cutting edge EMBO J 31 1630 1643 Staes A Impens F Van Damme P Ruttens B Goethals M Demol H Timmerman E Vandekerckhove J and
