ABSTRACT:

Plant viruses are obligate parasites infecting specific plant hosts. They infect their hosts either singly or in combination, concurrently or at intervals. The latter condition is referred to as mixed or multiple infection and it is most common phenomenon in nature, where a single host is found to have many viruses infecting itat a point in time. The viruses in mixed infection phenomenon may be homogenous in nature, sharing similar characteristics in common; a situation that often results in antagonism between or among the viruses. On the other hand, synergism occurs when heterologous viruses with dissimilar traits infect a host plant. Plants defend themselves when infected by plant viruses by using pre-existing and induced structural and biochemical defence mechanisms such as hypersensitive response (HR) and Ribonucleic acid (RNA)silencing among others. The details of the afore mentioned highlighted items and insights for further research have been discussed.
