According to a review of gene editing techniques, the CRISPR/Cas method has the potential to be a 'savior' for rice crops facing challenges from climate change and high food demand. A study on gene editing shows CRISPR/Cas may be the answer to saving rice crops facing challenges from climate chan
CRISPR is a revolutionary gene editing tool that allows scientists to make precise changes to the DNA of an organism with remarkable ease and accuracy. By using an enzyme called Cas9 guided by a small RNA molecule, CRISPR enables the targeting and modification of specific genes, opening up new possibilities for research and applications in fields such as medicine, agriculture, and biotechnology.
The study, published in CABI Reviews, highlights that rice, a cereal consumed by billions worldwide, is facing production and quality challenges due to climate stressors. Despite rice providing sustenance for three billion people, it is being impacted by both biotic and abiotic stress caused by the changing climate.
“Although great progress has already been achieved by conventional breeding, biotechnological tools, such as transgenics and genome editing, can aid in meeting future demands. The study outlines that a 50% increase in the current consumption of rice is projected for 2050 – which would mean a demand as high as 1.125 billion tonnes.
Dr. Costa de Oliveira added, “The high potential of CRISPR/Cas9 editing, for instance, has aided in the development of broad-spectrum resistance against bacteria, fungi, and viruses by silencing susceptibility genes and the insertion of resistance genes.
