Movie 5

Animation time course (300 time steps) showing auxin, cytokinin (ck), PIN (pin) and the generic cytokinin response gene that drives division (div) in the simulation of the LHW induction line. Starting from an eight cell template, growth is activated after 100 time steps, then to simulate the induction of LHW the production rate of cytokinin is increased after 200 time steps for the remainder of the time course. The induction of LHW promotes cell division, growth, and the formation of an additional xylem pole. Growth is limited by limiting the number of cells at 16.
