Abstract:
Plant viruses cause crop losses in agronomically and economically important crops, making global food
security a challenge. Although traditional plant breeding has been effective in controlling plant viral diseases, it is
unlikely to solve the problems associated with the frequent emergence of new and more virulent virus species or strains.
As a result, there is an urgent need to develop alternative virus control strategies that can be used to more easily contain
viral diseases. A better understanding of plant defence mechanisms will open up new avenues for research into plantpathogen interactions and the development of broad-spectrum virus resistance.
The scientific literature was evaluated and structured in this review, and the results of the reliability of the methods of
analysis used were filtered. As a result, we described the molecular mechanisms by which viruses interact with host plant cells.
To develop an effective strategy for the control of plant pathogens with a significant intensity on the agricultural
market, clear and standardised recommendations are required. The current review will provide key insights into the
molecular underpinnings underlying the coordination of plant disease resistance, such as main classes of resistance
genes, RNA interference, and the RNA-mediated adaptive immune system of bacteria and archaea – clustered regularly
interspaced short palindromic repeats (CRISPR) and CRISPR-associated Cas proteins – CRISPR/Cas.
Future issues related to resistance to plant viral diseases will largely depend on integrated research to transfer
fundamental knowledge to applied problems, bridging the gap between laboratory and field work.
