Describe how plant viruses are transmitted
WebPlant viruses, in general, do not have any specific mechanism for attachment to host cells. They are transmitted passively by several means. Tobacco mosaic virus (TMV) and some other plant viruses are carried by wind, rain drops, gardening equipment and grazing animals to host plants. WebSeed transmission of plant viruses results from the three-way interplay of the genetic components of the virus, the maternal host and its progeny. The challenge is to use genetic and cell biological analyses, integrated with our knowledge of plant reproduction and embryo development, to dissect this complex and rather poorly understood process.
