Some control measures are nonselective affecting a wide range of viral pathogens or their vectors, but othe
Klug, 2010), and many 'firsts': the first plant virus RNA sequenced, the first defined movement protein (MP), the first demonstration of the efficacy of transgenic coat protein (CP) expression for protection from infection, the first plant breeding and molecular evidence of a gene-for-gene resistance interaction and, more recently,
the overall understanding of viruses in many aspects. II. HISTORY. Although many early written and pictorial records of diseases caused by plant viruses are available, they are do not go back as far as records of human viruses. The earliest known written record of what was very likely a plant. 3. Comparative Plant Virology
This is the fifth fact sheet in a series of ten designed to provide an overview of key concepts in plant pathology. Plant pathology is the study of plant disease including the reasons why plants get sick and how to control or manage healthy plants.

Management of plant virus and viroid diseases is a matter of vital importance and concern to the farmer, horticulturist, forester and gardener.

This chapter focuses on those living organisms that cause disease: fungi, water molds, bacteria, viruses, nematodes, phytoplasmas, and parasitic plants. History & Significance. Plant loss to homeowners may result in frustration and minor monetary cost. However, on a global scale, plant diseases cause an estimated $38.

Viroid- and virus-like sy.rnptoms have been recognised in plants for a very long time. Viroid-like symptoms were described in citrus fruit
