Natural Resistance Mechanisms of Plants to Viruses

捕鯨魚叉

Applied Aspects of Induced Resistance to Plant Virus Infectionor its “survival”. The efficiency and extent of spread of infection within a plant are important factors for allowing the virus to be accessible to its vector(s), which in turn allows for dispersal of the virus to new plants and crops. If dispersal by a vector, such as an insect, is not part of the

Once a virus enters the cell, it must be able to express each of its proteins, replicate its genome, move from one cell to another, and then gain access to the host vascular system to move out of the initially infected leaf to other parts of the plant. At each ste

However, in those instances when a virus is able to infect a plant, host survival relies on quick recognition of the invading virus and rapid signaling of a defense response. On
