Calendar Name: seminars Scheduled for: Tuesday, March 12 2013, 14:00 - 15:30 Event text: Dr Staffan Persson Max-Planck-Institute for Molecular Plant Physiology Potsdam GERMANY Details: �A blueprint for cellulose synthesis in higher plants� ABSTRACT Cellulose is one of the most abundant and important biopolymer on our planet. It provides rigidity for anisotropic cell growth and plant morphology, and constitutes an essential raw material for many important industrial applications, including biofuels and materials. Cellulose is synthesized by plasma membrane located cellulose synthase (CesA) proteins that track along cortical microtubules in elongating interphase cells. We discovered the protein (CSI1/POM2) that provides the functional link between the CesAs and the microtubules. This discovery was partly based on the similar expression, or co-expression of the CSI1/POM2 gene and the CesA genes. Interestingly, we have found that many genes that are co-expressed with the CesA genes indeed are important for cellulose production. We extended this analysis and found that certain patterns of functionally related genes formed co-expressed gene modules, and that these modules have been duplicated and subsequently sub-functionalized many times. Through evolutionary estimates we could furthermore conclude that these duplication events were associated with specific events during plant evolution. We propose that plants use the duplication of co-expressed gene modules to create new functions through neo- or sub-functionalization of members in the modules, and that this may serve as a basis for the development of new biological processes in plants.

Calendar Name: seminars Scheduled for: Thursday, February 28 2013, 11:00 - 12:30 Event text: Dr Wolfgang Busch Gregor Mendel Institute Vienna AUSTRIA Details: �Genome-wide association study at the cellular level reveals novel regulators of root development� ABSTRACT Development is ultimately regulated at the cellular level. The coordinated growth and development of cells underlie both form and function of tissues and eventually the whole organism. Assuming that assessing natural variation at the cell type level might facilitate the identification of novel developmental regulators using quantitative genetics, we set out to quantify the cellular architecture of the root in more than 200 natural accessions of Arabidopsis thaliana utilizing automated confocal microscopy. We found widespread natural variation of morphology at the cell-type level and used this variation to conduct genome wide association mapping. Using expression data to identify candidate genes in proximity of significantly associated genome regions, and subsequent characterization of T-DNA insertion lines for those genes, we identified two novel regulators of root development. While the F-Box family gene KUK is involved in coordinating meristem length and terminal cell size, another novel gene, which we designated AUT, encodes a small protein that regulates the width of the root vasculature. Our work not only uncovered two novel players in root development but also demonstrated the feasibility of GWA at the cellular level to identify causal genes for basic biological processes such as development.

Calendar Name: seminars Scheduled for: Thursday, February 21 2013, 11:00 - 12:30 Event text: Prof Geert De Jaeger VIB, Dept. of Plant Systems Biology Ghent University Gent BELGIUM Details: �Targeted interactomics in plants through protein complex isolation� ABSTRACT TAPtag technology is the most widely applied tool to pick up in situ protein interactions in a proteome wide setting. Our research team has developed a versatile TAP technology platform for protein complex isolation from plants. We isolated complexes for hundreds of proteins and extensively demonstrated the power of our technology for protein discovery, functional analysis of proteins and protein complexes, and the modelling of protein networks. Complexes are purified from Arabidopsis cell suspension cultures or seedlings and we are currently translating the technology towards crop plants to bring complex purification in a developmental context.
