	Auxin and Auxinic Herbicide Mechanisms of Action This animation illustrates how auxins and auxinic herbicides may elicit responses in plant cells. It describes basipetal transport of auxins via influx and efflux carriers and displays a scenario of auxin action where auxin receptors recognize auxins and auxinic herbicides, which then induce a signal transduction cascade to turn on various gene products. The role of these gene products in plant response is shown as well. View
