Biomathematics Seminar: Mathematical Modelling of the Phargmoplast

Presented by Bernard Piette, University of Durham

13 December 2011 14:00 in CM105

In my talk I will be describing joined work with Andrei Smertenko and Patrick Hussey where we have combined new experimental results and mathematical modelling to propose a new model of phragmoplast formation.

The phragmoplast is a structure made out principally of microtubules and that
most plant cells generate after mitosis to form a membrane than joins the opposite ends of a cell before it divides in 2.

Following the experimental work of Asada et al. in 1992, the phragmoplast
was widely accepted as being made out of long treadmilling microtubules
sliding from the middle section of the phragmoplast towards its edges.

Using our experimental results and mathematical Modelling we have shown that Asada's model is incorrect: the microtubules in the phragmoplast
are dynamics, shorter than the phragmoplast width, do not slide and most of them treadmill from both ends.
