Book Description

Learn to produce healthier crops and better harvests!

This uniquely valuable book highlights the tremendous progress of knowledge in different areas of the field over the last decade. Here you'll find new and useful information about plant molecular virology and how the field can improve the world food situation in the coming years.

The last decade has seen remarkable advances in plant virological research, owing mainly to the rapid progress made in molecular biology and genetic engineering in recent years. While recombinant DNA technology has significantly contributed to our understanding of plant viruses, new findings are being accumulated every day as reported in various publications. Plant Viruses As Molecular Pathogens is the only book to bring you all of this information--22 chapters--in a single volume, compiled by specialists around the globe!

Use Plant Viruses As Molecular Pathogens to enhance your knowledge of:

  • current virus taxonomy
  • the molecular basis of virus transmission
  • movement of plant viruses
  • replication and gene expression of RNA/DNA viruses
  • resistance to viruses
  • molecular epidemiology
  • recombination events and possible mechanisms
  • molecular diversity
  • novel aspects of plant virus detection technologies
With helpful illustrations, photos, figures, models that explain viral mechanisms, and easy-to-understand reference tables, Plant Viruses As Molecular Pathogens will stimulate your thinking on this fascinating area of plant science!
