ABSTRACT

Abstract | Crops are threatened by plant viruses worldwide as they hack the host machinery for their reproduction. Plants have undergone continuous evolution and have equipped themselves with counter defense and tolerant strategies against viral infections. In the 21st century, considerable progress has been made in understanding the available natural resistance in plants against viral threats. The review aims to explain the molecular mechanisms involved in triggering the antiviral resistance in plants. Antiviral RNA silencing, R-gene mediated resistance and host factor related recessive resistance are categorized as most beneficial plant defense approaches used by plants. The review also briefly explains about introgression of durable resistance to generate virus resistant cultivars for economically important crops through molecular breeding techniques via utilizing advanced molecular markers involving cis and trans genetics. The review adhere recent research findings regarding disease resistance against viral diseases and concludes via shedding light upon the future prospects in this exciting field of research.
