Calendar Name: seminars Scheduled for: Tuesday, April 17 2012, 14:00 - 15:30 Event text: Prof Jaideep Mathur Laboratory of Plant Development and Interactions Department of Molecular and Cellular Biology University of Guelph Guelph Ontario CANADA Details: �Organelle Extensions: Uncovering new facets of subcellular behaviour for maintaining homeostasis in plants� ABSTRACT Despite their inability to move away from stressful conditions, plants, in comparison to animals, have much longer life spans. How do plants manage stress while remaining 'rooted' to a spot? Perhaps, plant cells are able to respond to environmental stimuli rapidly and minimize subcellular stress levels before they become intolerable. Perhaps they do not need to move away! This fundamental thinking forms the basis for research in my lab. Using a judicious combination of molecular-genetic techniques including a wide range of targeted fluorescent protein probes, normal and mutant transgenic plants we have started uncovering the rapid sub-cellular response machinery in plants. We find that instead of dividing, many organelles extend their surfaces transiently by creating thin protrusions that can extend for considerable distances within the cell. This �primary� membrane-aided response prevents the build up of toxic by-products within the cell. Alternatively, organelle extensions are used for metabolite dispersal and exchange, as well as for �squeezing� past other organelles in narrow vacuole-dominated intracellular spaces. Notably, persistent stress acting on membranes does trigger molecular cascades that over a longer time scale result in division of organelles. Live-imaging of organelle extensions and their dynamic interactions challenges our view of the static plant cell built up using snapshots from fixed tissues and paves the way for a better understanding of plants and their rapid subcellular responses.

Calendar Name: seminars Scheduled for: Friday, April 13 2012, 14:00 - 15:30 Event text: Prof Enrico P� Institute of Life Sciences Scuola Superiore Sant'Anna di Pisa Pisa ITALY Details: �Quantitative Genomics: Exploring the genetic architecture of heterosis in maize� ABSTRACT The seminar will describe the approaches of quantitative genetics and genomics applied to identify heterotic QTL in maize and the difficult and somehow frustrating effort in trying to physically isolate the corresponding loci. In this seminar the development and fine genotypic characterization of near-isogenic lines for selected heterotic QTL will be described. Finally it will be presented a new large multi-parental population recently produced in maize and the challenge posed by its characterization.

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.
