Biochemical studies on plant virus RNA replication have advanced considerably since 2000, primarily because of new genetic, molecular, biochemical, and enzymatic studies. This book generates understanding of multiplication of plus-sense RNA plant viruses, especially at molecular level. Certain virus-encoded essential proteins, nucleotide sequence motifs, and RNA secondary structures are central to virus RNA replication, which has a number of stages. Each is a complex phenomenon requiring specific factors and conditions.
