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. Viruses are known to infect both plant cells and animal cells. Since viruses are obligate intracellular parasites they must develop direct methods of transmission, between hosts, in order to survive. The mobility of animals increases the mechanisms of viral transmission that have evolved, whereas plants remain immobile, and thus plant viruses must rely on environmental factors to be transmitted between hosts.
