Antiviral activity of ribosome inactivating proteins for management of plant viral infection

Abstract

In nature, plants exhibit various defense mechanisms to protect themselves from viral infection. Reported to harbor virus-inhibiting compounds like Ribosome inactivating proteins (RIPs). It's a matter of how we explore, identify, and utilize RIPs in managing a given stress. RIPs have been found to contain antiviral, anticancer, and neurotoxic effects and are used in various biomedical and agricultural fields. The expression of RIPs could be enhanced in plants to improve their defense against biotic and abiotic stresses. Identification of new RIPs and genetic sequencing led to the development of new phylogenetic theories. Studies on the interaction between RIPs and cells have increased the knowledge regarding the handling of exogenous proteins by cells. The review provides a brief historical preview, classification, mode of action, and broader applications with a special focus on managing plant viral diseases and concerns to mankind.
