Researchers use CRISPR/Cas9 to alter upstream DNA, boosting gene expression and photosynthesis in a food crop for the first time.
A team of researchers has exhibited, for the first time, the ability of CRISPR-based gene editing to alter photosynthesis.
According to researchers, the research marks the first unbiased attempt to elevate gene expression and enhance downstream photosynthetic activity. In contrast to synthetic biology techniques that employ genes from other living forms to enhance photosynthesis, all plants naturally possess the genes responsible for photoprotection.
The strategy of the lab was to modify the DNA upstream of the target gene, which regulates the amount and timing of gene expression, using CRISPR/Cas9. They intended to analyze how much those modifications would affect downstream activities.“We were a little bit surprised, but I think it goes to show how much plasticity plants and crops have. They’re used to these big changes in their DNA from millions of years of evolution and thousands of years of domestication,” said Patel-Tupper.
