Calendar Name: seminars Scheduled for: Wednesday, December 16 2009, 15:00 - 16:30 Event text: Dr M. Madan Babu MRC Laboratory of Molecular Biology University of Cambridge UK Details: ABSTRACT Altered abundance of several intrinsically unstructured proteins (IUPs) has been associated with perturbed cellular signaling that may lead to pathological conditions such as cancer. Therefore, it is important to understand how cells precisely regulate the availability of IUPs. We observed that regulation of transcript clearance, proteolytic degradation, and translational rate contribute to controlling the abundance of IUPs, some of which are present in low amounts and for short periods of time. Abundant phosphorylation and low stochasticity in transcription and translation indicate that the availability of IUPs can be finely tuned. Fidelity in signaling may require that most IUPs be available in appropriate amounts and not present longer than needed.

Calendar Name: seminars Scheduled for: Monday, December 7 2009, 11:00 - 12:30 Event text: Prof Cris Kuhlemeier Institute of Plant Sicences University of Bern Bern Switzerland Details: �Auxin and Phyllotaxis� ABSTRACT Phyllotaxis, the regular arrangement of leaves or flowers around a plant stem, is an example of developmental pattern formation and organogenesis. Phyllotaxis is characterized by the divergence angles between the organs, the most common angle being 137.5�, the golden angle. Models of phyllotaxis must explain its de novo establishment in the radially symmetric embryo, the stable maintenance of the different arrangements and the observed transitions between phyllotactic patterns. Most importantly, they must explain the specific divergence angles of 180�, 90�, 137.5� and in rarer cases other angles as well. This quantitative aspect makes phyllotaxis an unusual developmental problem. It has traditionally attracted the interest of mathematicians and computer scientists, who have constructed a wide variety of simulation models. To the biologist it is surprising that only minimal assumptions about the underlying molecular mechanisms are sufficient to arrive at mathematical models that correctly and robustly recreate phyllotactic patterns. In this presentation I will give an overview of the experimental work on phyllotaxis and how these experiments form the basis for a new generation of simulation models. The interplay between modeling and experiment will be discussed. Kuhlemeier, C., Phyllotaxis. Trends Plant Sci., 2007. 12: p. 143-150.
