Cell-to-cell signaling is essential for normal development and physiology. In both plants and animals, cells secrete proteins or peptides that influence the behavior or fate of neighboring cells. However in plants, signaling is also possible through direct transport of transcription factors between cells. Here we discuss some of the signaling pathways mediated by mobile transcription factors and their implications for plant growth and development.
细胞间信号转导对于正常的发育和生理功能至关重要。在植物和动物中，细胞分泌的蛋白质或肽类物质会影响邻近细胞的行为或命运。然而，在植物中，信号转导也可以通过转录因子在细胞间的直接运输来实现。本文讨论了一些由可移动转录因子介导的信号通路及其对植物生长发育的影响。
