“…This implies the presence of specific host machinery guiding or directly facilitating the movement of the PSTVd through the cytoplasm [ 59 ]. The cytoskeleton, a dynamic network of protein filaments, imparts structural support to cells and participates in various cellular processes, including that of intracellular transport [ 60 , 61 ]. Myosins, motor proteins responsible for movement along actin filaments, have long been considered key players in the movement of certain viral proteins in plant cells [ 62 , 63 , 64 ].…”

Viroids represent distinctive infectious agents composed solely of short, single-stranded, circular RNA molecules. In contrast to viruses, viroids do not encode for proteins and lack a protective coat protein. Despite their apparent simplicity, viroids have the capacity to induce diseases in plants. Currently, extensive research is being conducted on the replication cycle of viroids within both the Pospiviroidae and Avsunviroidae families, shedding light on the intricacies of the associated host factors. Utilizing the potato spindle tuber viroid as a model, investigations into the RNA structural motifs involved in viroid trafficking between different cell types have been thorough. Nevertheless, our understanding of the host factors responsible for the intra- and inter-cellular movement of viroids remains highly incomplete. This review consolidates our current knowledge of viroid replication and movement within both families, emphasizing the structural basis required and the identified host factors involved. Additionally, we explore potential host factors that may mediate the intra- and inter-cellular movement of viroids, addressing gaps in our understanding. Moreover, the potential application of viroids and the emergence of novel viroid-like cellular parasites are also discussed.

“…Cell identity in plants is primarily governed by a range of mobile signals, including proteins, RNAs, and hormones that travel through the symplastic route, made up of plasmodesmata connecting cytosols of adjacent cells (6)(7)(8)(9). For example, the transcription factor SHORTROOT (SHR) is produced in the root internal stele and actively transported through plasmodesmata to the surrounding endodermis and quiescent center (QC) tissues, where it enters the nucleus (10)(11)(12).…”

The excision of the root tip, including the stem cell niche, triggers rapid regeneration from remnant cells in the stump. In plants, cell identity relies on positional information transported through cytoplasmatic bridges known as plasmodesmata. However, how such information is reset to allow the regeneration of lost identities is unknown. Here, we show that the movement of mobile signals is temporarily restricted near the incision site and that regeneration-induced members of the LATERAL ORGAN DOMAIN (LBD) plant-specific developmental regulators are necessary and sufficient for this restriction. Regeneration was disrupted in high-orderlbdmutants but was restored by transient localized plasmodesmata closure. We propose that LBD-mediated modulation of intercellular connectivity is crucial for plant regeneration and may have widespread roles inde novopattern formation.One Sentence SummaryPlant-specific DNA binding genes mediate a transient restriction of intercellular communication to allow root regeneration
