Movie 1: Movement of the LFY Transcription Factor in the Meristem through Plasmodesmata

This animation shows how the LFY transcription factor is synthesized only in Layer 1 of this genetically altered meristem and then moves through plasmodesmata into the underlying layers (L2 and L3) to influence gene transcription of the meristem. That LFY is functional after moving through plasmodesmata is demonstrated by the activation of a reporter gene and is shown by the appearance of a blue color when X-Gluc is added to the plant. Animation created by Carin Cain with scientific input from Richard A. Jorgensen/University of Arizona and William J. Lucas/University of California at Davis.
