Calendar Name: seminars Scheduled for: Thursday, March 22 2012, 11:00 - 12:30 Event text: Prof Bruno Cammue Faculty of Bioscience Engineering Centre of Microbial and Plant Genetics Department of Microbial & Molecular Systems K.U.Leuven Leuven BELGIUM Details: �From basic plant pathology research to fungal disease control in plants and humans� ABSTRACT Early research at the �Plant-Fungus Interaction� group of the Center of Microbial and Plant Genetics (CMPG-PFI) on novel antifungal plant proteins has led to the discovery of the so-called plant defensins (PDFs), basic peptides with antimicrobial activities. Subsequent research at CMPG-PFI focused in one research unit on the function of these PDFs in planta, including their possible role in the plant�s defense against necrotrophic fungi, and was recently extended to other novel stress-induced peptides. In the other research unit, the mode of antifungal activity of these PDFs was studied. Based on that expertise CMPG-PFI developed a platform for the discovery of novel antifungals with potential applications in agriculture, material protection and medical applications. The latter include treatment of fungal biofilms and the development of next-generation implants.

Calendar Name: seminars Scheduled for: Monday, March 12 2012, 11:00 - 11:30 Event text: Prof Silke Robatzek The Sainsbury Laboratory Norwich UNITED KINGDOM Details: �Plants communicating with pathogens: membranes in motion and cellular defense� ABSTRACT Cell surface receptors of plant cells constitute recognition sites to detect invading pathogens and to active defenses. Arabidopsis FLS2 encodes the receptor kinase for bacterial flagellin (flg22) and is required for immunity against a broad-spectrum of potentially pathogenic bacteria. Upon flg22 perception FLS2 accumulates at plasma membrane microdomains and is internalized. Although receptor trafficking became a focus of research in the past years, there is largely nothing known about downstream molecules and regulatory components of receptor endocytosis. I will present quantitative high throughput confocal imaging in plants and will discuss results from our current research, which addresses the identity of the FLS2 endosome, molecular components regulating FLS2 endocytosis, and the interception of FLS2 endocytosis and flg22 signaling. These results provide good evidences for a role of late endosomes/multivesicular bodies in plant immunity. To further study cellular defenses we focus on stomatal closure as a first layer of plant immunity. I will describe approaches using high throughput confocal imaging for the genetic dissection of stomata response pathways, and present exciting data how pathogens inhibit stomatal closure by interference with hormonal signaling. Altogether, these studies allow us to better understand the molecular mechanisms underlying the subcellular changes in plant-pathogen interactions.

Calendar Name: seminars Scheduled for: Friday, March 9 2012, 14:00 - 15:30 Event text: Prof Wout Boerjan VIB, Dept. of Plant Systems Biology Ghent University Gent BELGIUM Details: �Engineering lignin for biofuels� ABSTRACT Lignin is an aromatic polymer that is abundantly present in secondarily-thickened plant cell walls. It confers rigidity to the wall and allows transport of water and solutes through the vascular system. However, lignin plays a negative role in a number of agro-industrial processes, such as pulping and forage digestibility and it is also one of the most important limiting factors in the conversion of plant cell walls to fermentable sugars in the process to liquid bio-fuels. Hence, significant research efforts have been devoted to understand the lignin biosynthesis pathway and the effects of down-regulation of individual steps of this pathway on lignin amount and composition, and on wood properties. These studies have shown that lignin amount and composition can be altered, often without apparent negative consequences for plant health. The first results obtained from poplar field trials will be used to illustrate how lignin engineering can improve biomass processing. Furthermore, we have taken a systems biology approach involving transcriptomics and metabolomics in Arabidopsis to study how the plant, as a biological system, copes with perturbations in the lignin biosynthesis pathway, to reveal regulation within this pathway and to identifying novel genes with potential economic value. Finally, an example will be presented how natural variation in the poplar germplasm can be exploited in a reverse genetics strategy to identify gene function and to accelerate tree genetic improvement.
