Council and Parliament reach provisional deal on a set of rules for new genomic techniques, aiming to improve the competitiveness of European agriculture and support the sustainability of our food sys...

The activity of the eukaryotic OMEGA-Fanzor genome editing system remains limited in plants. We engineered the Fanzor nucleases SpuFz1, GtFz1, NlovFz2, and MmeFz2 in plants, with NlovFz2 being the mo...

Custom DNA constructs have never been more common or important in the life sciences. Many researchers therefore devote substantial time and effort to molecular cloning, aided by abundant computer-aide...

Genome editing is a technology that enables targeted mutagenesis. Notably, site-directed nucleation (SDN)-1 genome editing, which does not involve the incorporation of foreign DNA sequences and can introduce the same mutations as naturally occurring mutations, is not subject to genetically modified organism (GMO) regulations in many countries if transgenes are segregated out. This makes it an attractive strategy for crop improvement. Multiple DNA double-strand breaks introduced via genome editing may lead to inversions or translocations. If these genomic alterations involve promoter regions, a promoter/enhancer replacement may occur, thereby altering target gene expression as desired. Because conventional SDN-1 genome editing primarily induces loss-of-function mutations, promoter/enhancer replacement by genome editing (PERGE) represents a new paradigm in genome editing for crop improvement.

Although metagenomic sequencing has revealed a rich microbial biodiversity in the mammalian gut, methods to genetically alter specific species in the microbiome are highly limited. Here, we introduce ...
