Intercellular communication by the direct trafficking of transcription factors has been reported in plant developmental events such as root radial or epidermal cell patterning and shoot organogenesis. Investigations of this novel communication system have just begun and have highlighted the structural requirements for and mechanisms of transcription factor movement. Early studies suggest that plants employ both targeted (selective) and non-targeted (non-selective) intercellular movement of transcription factors. Factors that affect the intercellular movement of transcription factors through plasmodesmata have been explored.
