Mechanisms of plant virus cell-to-cell transport: new lessons from complementation studies.

This article, published in Frontiers in Plant Science, discusses the mechanisms of plant virus cell-to-cell transport. The authors focus on complementation studies involving viral movement proteins (MPs) and movement-deficient plant viruses. They provide examples of complementation studies with different plant viruses and discuss the potential mechanisms behind these complementations. The article emphasizes the importance of viral MPs in facilitating the transport of viral genomes through plasmodesmata, the channels connecting neighboring plant cells. The document also explores the ability of certain proteins to complement the transport of RNA viruses, specifically geminivirus C5 and P3 of the fungal virus. These proteins modify plasmodesmata, leading to actin remodeling and inhibition of callose deposition. The document also covers the specificity of transport through plasmodesmata and the mechanisms by which viral movement proteins provide selective intercellular transport. Additionally, the document provides a list of references for various scientific articles related to virology and plant viruses, which can be valuable for researchers studying plant viruses and their interactions with host plants.
