The types of cells and tissues infected by a virus define its tissue tropism. Determinants of tissue tropism in animal-infecting viruses have been extensively investigated, but little is known about plant viruses in this regard. Some geminiviruses in the genus Begomovirus exhibit phloem limitation and are restricted to cells of the vascular system, whereas others can invade mesophyll tissue. To identify viral genetic determinants of tissue tropism, we established a model system using two… CONTINUE READING
