Summary
RNA interference (RNAi) offers powerful gene silencing for crop protection. This technology develops resilient crops against pests and pathogens, enhancing sustainable agriculture.
Area of Science:
- Molecular Biology
- Plant Science
- Genetics
Background:
- RNA interference (RNAi) is a conserved gene silencing mechanism in eukaryotes.
- Small RNAs (siRNAs and miRNAs) are key regulators of RNAi.
- RNAi is crucial for physiological and developmental processes.
Purpose of the Study:
- To review recent advances in RNAi-mediated crop protection strategies.
- To highlight RNAi's role in developing crops resistant to biotic stresses.
- To discuss future research directions for RNAi in agriculture.
Main Methods:
- Review of current literature on RNAi applications in crop protection.
- Analysis of RNAi-based strategies against various biotic stresses (viruses, bacteria, fungi, insects, nematodes).
- Synthesis of findings on RNAi-induced crop resilience.
Main Results:
- RNAi technology enables targeted gene suppression in crops.
- RNAi has been successfully applied to develop crops resistant to diverse biotic threats.
- Significant progress has been made in utilizing RNAi for sustainable crop production.
Conclusions:
- RNAi is a vital tool for enhancing crop protection and resilience.
- Continued research in RNAi holds promise for future agricultural advancements.
- RNAi contributes to food security by mitigating crop losses from biotic stresses.

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...
