A new application of the CRISPR/Cas molecular scissors promises progress in crop cultivation. At Karlsruhe Institute of Technology (KIT), researchers have succeeded in modifying the sequence of genes on a chromosome using CRISPR/Cas. For the first time, they took a known chromosome modification in the thale cress model plant and demonstrated how inversions of the gene sequence can be undone and inheritance can thus be controlled. The results are published in Nature Communications (DOI: 10.1038/s41467-020-18277-z).
