Multiplication of RNA Plant Viruses [Paperback]

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.

Multiplication is the basic biological function of all organisms and is dependent upon replication of genomes. This is also true of plant viruses even though they possess a minimum of essential genetic information. Phylogenetically, replication-associated genes constitute the core elements of RNA virus genomes while other gene modules are considered as accessory elements. However, the biochemical studies on plant virus RNA replication were in their infancy even in 1999-2000. The picture has improved much since structural and sequence requirements of viral RNA replication, and synthesis are beginning to be understood, primarily because of the genetic, molecular, biochemical, and enzymatic studies conducted during the last six years. 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 stage is a complex phenomenon requiring specific factors and conditions. All this has generated much new information so that replication of plus-sense RNA plant viruses has now emerged as a rapidly developing field. However a lot of distance still has to be covered and traversing this distance could prove difficult because no one organised corpus of knowledge is available. Hopefully, this book fills the niche and generates understanding of multiplication of plus-sense RNA plant viruses, especially at molecular level. Nearly alll3)
