Genetic engineering (GE) approaches have been effectively deployed to incorporate
foreign genes of economic and/or agricultural importance in crops. Ever
since Powell et al. in 1986 showed virus resistance through GE approach, numerous
crop plants have been genetically modified to impart virus resistance. Greater
understanding of host-virus interactions in the wake of RNA silencing phenomenon
have further opened up small non-coding RNAs based virus management
strategies. This chapter discusses research priorities, approaches and accomplishments
in the field of virus resistant transgenic plants in India. Various genetic
modification strategies namely coat protein mediated resistance through RNA
silencing have been successfully deployed to develop virus resistance. Transgenic
lines have been licensed to private sector, in crops like tomato, and significant
progress has been made in crops like potato, rice etc. However, a major bottle-neck
in developing successful transgenic crop in legumes, cucurbits and other
crops, where viral infection is a serious menace is the lack of suitable regeneration
and transformation protocols. Hence, this chapter also deliberates upon
potential pitfalls of genetic engineering approaches that require intensive research
efforts. Further, as a way forward, it is also proposed to explore recently emerging
genome editing tools to combat phytopathogenic viruses.
