摘要胞间连丝（Plasmodesmata，PD）在器官的发育和形成中起着重要作用。定位和/或相互作用调节PD的蛋白质已经被鉴定出来。新的移动的转录因子和RNA支持PD在器官形成中的作用。还讨论了共质体运输在生长素信号传导中的重要性。细胞之间的通信是协调器官形成和组织形成的关键步骤。在植物中，代谢物和信号分子的细胞间运输通过穿过细胞壁连接相邻细胞的细胞质和内质网的膜结构（称为胞间连丝）共质体地发生。本文综述了共质体通讯在植物发育中的重要作用。我们回顾了目前的文献报道的影响，不断变化的胞间连丝在细胞形态发生，器官的启动和分生组织的维护和评论最近的工作，涉及到新的胞间连丝监管机构和移动的发展蛋白质和RNA分子的鉴定。还讨论了解开胞间连丝的动态调节和功能的新机会。
HighlightsPlasmodesmata (PD) play a role in organ development and patterning.Proteins that localize and/or interact to regulate PD have been identified.Novel mobile transcription factors and RNAs support PD role in organ formation.The importance of symplastic transport in auxin signalling is also discussed.Communication between cells is a crucial step to coordinate organ formation and tissue patterning. In plants, the intercellular transport of metabolites and signalling molecules occur symplastically through membranous structures (named plasmodesmata) that traverse the cell wall to connect the cytoplasm and endoplasmic reticulum of neighbouring cells. This review aims to highlight the importance of symplastic communication in plant development. We revisit current literature reporting the effects of changing plasmodesmata in cell morphogenesis, organ initiation and meristem maintenance and comment on recent work involving the identification of novel plasmodesmata regulators and of mobile developmental proteins and RNA molecules. New opportunities for unravelling the dynamic regulation and function of plasmodesmata are also discussed.
