Abstract:
A fascinating aim of current research is the understanding
of the developmental processes through which multicellular
organisms acquire their form. Mathematical models and
computer simulations are an emerging methodology assisting
in these studies. The talk will describe the work in
progress aimed at creating an integrative model of
Arabidopsis thaliana. The model takes into account the
spiral phyllotaxis, apical dominance, flowering sequences,
and architecture of wild type and selected mutant
Arabidopsis plants. By combining computational models and
simulations operating at different scales, we have begun to
synthesize developmental processes from the level of
molecules to the level of the whole plant architecture. This
makes it possible to appreciate the link between the
relatively simple mechanisms operating at the levels of
plant modules and tissues and the resulting complex plant
structures. These results have been obtained in
collaboration with Enrico Coen, Cris Kuhlemeier, and
Ottoline Leyser.
Biography
Przemyslaw Prusinkiewicz is a Professor of Computer Science
at the University of Calgary. He has been conducting
research in computer graphics since the late 1970s. In 1985,
he originated a method for simulating and visualizing plants
based on L-systems, a mathematical model of development. He
is a co-author of two books, "Lindenmayer Systems, Fractals
and Plants" and "The Algorithmic Beauty of Plants", as well
as numerous research papers. In 1997, he received the ACM
SIGGRAPH Computer Graphics Achievement Award for his work on
the modeling and visualization of biological structures.
