Role of intercellular movement of transcription factors in plant growth and development

The growth and development of multicellular organisms relies on substance exchange and signal transmission between cells. Cell fate specification is tightly controlled by signals from adjacent cells. Intracellular protein transport is widely involved in various developmental processes in plants. In this review, we summarize recent advances in the intercellular movement of key transcription factors controlling plant development. We also review the cellular basis and molecular regulatory models of movement. Finally, we discuss challenges and new techniques for studying intercellular protein movement.
