RNA Interference in Plants

RNA interference (RNAi) is a pivotal mechanism in plants for regulating gene expression and protecting against viral infections. This process involves the degradation of specific mRNA molecules through small interfering RNAs (siRNAs) or microRNAs (miRNAs), leading to a decrease in the expression of target genes. RNAi technology has been harnessed in agricultural biotechnology to develop crops with improved traits, such as resistance to pests and diseases. By designing RNAi constructs targeting specific genes, researchers can enhance plant resilience without altering the entire genome. Additionally, RNAi has applications in functional genomics, allowing scientists to investigate gene functions and regulatory networks in plants.
