Role of aptamers in plant defense mechanism against viral diseases

Abstract

The diseases of plants caused by viruses are always in main concern for researchers because they reduced the yield and quality of food grains or horticultural products like fruits, vegetables and flowers which will leads a major economic loss of agricultural stakeholders. Presently there is no direct control strategy for viral infection in plants. Advancement in technology leads a novel approach which uses peptide aptamers for controlling plant virus. This technology is effective because the peptide aptamers are specific and binds directly with the capsid protein (CP), nucleoproteins (N) and movement proteins (MP) and affect viral replication machinery of plant virus. In this chapter, we reviewed the about role of peptide aptamers for inhibiting the viral infection in plants.
