Abstract

Plants, animals, and other microorganisms are provided, in their genetic makeup, with a certain range of antimicrobial compounds. With respect to viruses, a few plants show resistance to their infection. This resistance, in many cases, has been associated with the protective chemicals within the plant cells which are known for their antifungal or antimicrobial property and reported to be proteinaceous in nature. Many higher plants have developed a variety of defense systems to combat pathogen attack which is essential for their survival. Some of these plants possess endogenous proteins that act as virus inhibitors. They are generally basic proteins with molecular weight ranging from 24 to 32 kDa and effective against a wide range of plant viruses. The viral inhibitors are well studied in Phytolacca americana, Dianthus caryophyllus, Boerhaavia diffusa, Cuscuta reflexa, Mirabilis jalapa, Bougainvillea spectabilis, and Celosia cristata. These viral inhibitors are most effective when mixed with the virus inoculum or when they are applied one day before or shortly after mechanical inoculation.
