It deals mainly with concepts rather than detail. The focus will be on plant viruses but due to the changing environment of how virology is taught, comparisons will be drawn with viruses of other kingdomes, animals, fungi and bacteria. It has been written for students of plant virology, plant pathology, virology and microbiology who have no previous knowledge of plant viruses or of virology in general.
- Boxes highlight important information such as virus definition and taxonomy
- Includes profiles of 32 plant viruses that feature extensively in the text
- Full color throughout
Advanced undergraduate and graduate students in basic and applied plant virology, plant pathology, microbiology, genetics and molecular biology, biological control, ecology, evolution, and related aspects of plant science

Roger Hull
Roger Hull graduated in botany from Cambridge University and undertook his graduate studies in plant virus diagnostics and epidemiology at London University. He lectured on agricultural botany there and at Makerere University in Uganda. In 1965 he moved to fundamental studies of plant viruses, first at Cambridge in the United Kingdom and then at the John Innes Institute (now Centre) in Norwich. He spent a sabbatical year (1974) at University of California, Davis, where he learnt the fundamentals of the newly developing molecular biology technology. He applied to this to plant virus characterisation, diagnostics and virus control, especially in tropical crops such as rice and plantain bananas. He retired in 1997 but continued research, lecturing and book writing. Dr Hull was an honorary professor at University of East Anglia in the UK and Peking and Fudan Universities in China, a Doctoris Honoris Causa at the University of Perpignan in France, and a Fellow of the American Phytopathological Society. He has published over 250 peer-reviewed papers on plant virology and more than 40 reviews in scientific journals, and has authored five books. In retirement Roger Hull also became involved in promoting the uptake of transgenic technology by developing countries as one approach to alleviating food insecurity. He was on the International faculty of the e-learning diploma course training decision makers, mainly in developing countries, in plant biotechnology regulation.
