Abstract: In order to adapt to the changes of environment, plants have evolved unique signaling mechanisms, almost each organ and tissue can form efficient signal transduction system. Intercellular movement refers to mechanisms that are specifically implemented during pattern formation in organs, tissues or between neighboring cells, in which transcription factors, peptides, small RNAs(sRNAs)and hormones have involved. The four types of mobile molecules mediate different signal transduction pathways, but they can interact with each other and constitute the entire intercellular signaling networks. As a kind of particular protein, transcription factors especially non-cell-autonomous transcription factors, play important roles in processes related to the formation and development of plant organs. This paper mainly summarizes the non-cell-autonomous transcription factors in plant and the mechanisms that transcription factors and other mobile molecules co-regulate plant meristem development.

Key words: Non-cell-autonomous transcription factors, Intercellular movement, Signal transduction, Meristem
