Abstract

Highlights: Plasmodesmata (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. Abstract : 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.
