Protease Types and Functions of Plant Pathogenic Viruses

There are numerous virus that infect the plants. After the plant viruses penetrated in to the host plant cells, they uncoat from coat protein for surviving and genome expression. Then viruses use the enzymes for replication and genome expression. The important enzymes for genome expression are proteases and replication enzymes. The proteases have important role for replication. In the review, structure of plant pathogenic viruses and functions are discussed
