Viruses can infect all types of organisms‚ from animals and plants to bacteria and archaea.[1] Since Dmitri Ivanovsky’s 1892 article describing a non-bacterial pathogen infecting tobacco plants‚ and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898‚[2] about 5‚000 viruses have been described in detail‚[3] although there are millions of different types.[4] Viruses are found in almost every ecosystem on Earth and are the

Gene Cloning of Cucumber Mosaic Virus and Some Related Viral Agents 1.1 Introduction Cucumber mosaic virus (CMV) is a typical member of the genus Cucumovirus. It has infected more than 1‚000 species of monocots and dicots‚ including many economically important crops (Palukaitis and García-Arenal‚ 2003; Palukaitis et al.‚ 1992). In China‚ CMV is commonly detected as the principal virus infecting field crops in the families Solanaceae (including tobacco‚ tomato‚ potato‚ pepper‚ etc.)‚ Brassicaceae

Edible plant vaccine against diarrhoea‚ expressed in potato‚ and antibody against dental caries‚ expressed in tobacco‚ is already in pre-clinical human trials. Attempts are being made to express many proteins of immunotherapeutic use at high levels in plants and to use them as bio-reactors of the modern era. MOST of the drugs used by man‚ until very recently‚ were

Chapter 18 The Genetics of Viruses and Bacteria Lecture Outline Overview: Microbial Model Systems Viruses and bacteria are the simplest biological systems—microbial models in which scientists find life’s fundamental molecular mechanisms in their most basic‚ accessible forms. Molecular biology was born in the laboratories of microbiologists studying viruses and bacteria. Microbes such as E. coli and its viruses are called model systems because of their use in studies that reveal broad biological

His main discovery was the structure of DNA‚ but he also discovered the helical construction of tobacco mosaic virus. The discovery of the molecular structure of DNA was a ginormous scientific breakthrough. Watsons current research includes the role of RNA in protein synthesis and invitro fertalization studies.

As weeds have grown resistant to glyphosate and other herbicides used in concert with resistant GM crops‚ companies are developing crops engineered to become resistant to multiple herbicides to allow farmers to use a mixed group of two‚ three‚ or four different chemicals.[71] Pathogen resistance – insects or viruses Tobacco‚ and
