Virus spread through plasmodesmata (Pd) is mediated by virus-encoded movement proteins (MPs) that modify Pd structure and function. The MP of Tobacco mosaic virus (TMVMP) is an endoplasmic reticulum (ER) integral membrane protein that binds viral RNA (vRNA). forming a vRNA:MP:ER complex. It has been hypothesized that TMVMP causes Pd to dilate. https://www.bekindtopets.com/quick-offer-Foil-Organza-p5733-flash-choice/
